php-encryption
|
||||
===============
|
||||
|
||||
[](https://travis-ci.org/defuse/php-encryption)
|
||||
|
||||
This is a library for encrypting data with a key or password in PHP. **It
|
||||
requires PHP 5.4 or newer.** The current version is v2.0.0, which is expected to
|
||||
remain stable and supported by its authors with security and bugfixes until at
|
||||
least January 1st, 2019.
|
||||
|
||||
The library is a joint effort between [Taylor Hornby](https://defuse.ca/) and
|
||||
[Scott Arciszewski](https://paragonie.com/blog/author/scott-arcizewski) as well
|
||||
as numerous open-source contributors.
|
||||
|
||||
What separates this library from other PHP encryption libraries is, firstly,
|
||||
that it is secure. The authors used to encounter insecure PHP encryption code on
|
||||
a daily basis, so they created this library to bring more security to the
|
||||
ecosystem. Secondly, this library is "difficult to misuse." Like
|
||||
[libsodium](https://github.com/jedisct1/libsodium), its API is designed to be
|
||||
easy to use in a secure way and hard to use in an insecure way.
|
||||
|
||||
Dependencies
|
||||
------------
|
||||
|
||||
This library requres no special dependencies except for PHP 5.4 or newer with
|
||||
the OpenSSL extensions enabled (this is the default). It uses
|
||||
[random\_compat](https://github.com/paragonie/random_compat), which is bundled
|
||||
in with this library so that your users will not need to follow any special
|
||||
installation steps.
|
||||
|
||||
Getting Started
|
||||
----------------
|
||||
|
||||
Start with the [**Tutorial**](docs/Tutorial.md). You can find instructions for
|
||||
obtaining this library's code securely in the [Installing and
|
||||
Verifying](docs/InstallingAndVerifying.md) documentation.
|
||||
|
||||
After you've read the tutorial and got the code, refer to the formal
|
||||
documentation for each of the classes this library provides:
|
||||
|
||||
- [Crypto](docs/classes/Crypto.md)
|
||||
- [File](docs/classes/File.md)
|
||||
- [Key](docs/classes/Key.md)
|
||||
- [KeyProtectedByPassword](docs/classes/KeyProtectedByPassword.md)
|
||||
|
||||
If you encounter difficulties, see the [FAQ](docs/FAQ.md) answers. The fixes to
|
||||
the most commonly-reported problems are explained there.
|
||||
|
||||
If you're a cryptographer and want to understand the nitty-gritty details of how
|
||||
this library works, look at the [Cryptography Details](docs/CryptoDetails.md)
|
||||
documentation.
|
||||
|
||||
If you're interested in contributing to this library, see the [Internal
|
||||
Developer Documentation](docs/InternalDeveloperDocs.md).
|
||||
|
||||
Examples
|
||||
---------
|
||||
|
||||
If the documentation is not enough for you to understand how to use this
|
||||
library, then you can look at an example project that uses this library:
|
||||
|
||||
- [encutil](https://github.com/defuse/encutil)
|
||||
- [fileencrypt](https://github.com/tsusanka/fileencrypt)
|
||||
|
||||
Security Audit Status
|
||||
---------------------
|
||||
|
||||
This code has not been subjected to a formal, paid, security audit. However, it
|
||||
has received lots of review from members of the PHP security community, and the
|
||||
authors are experienced with cryptography. In all likelihood, you are safer
|
||||
using this library than almost any other encryption library for PHP.
|
||||
|
||||
If you use this library as a part of your business and would like to help fund
|
||||
a formal audit, please [contact Taylor Hornby](https://defuse.ca/contact.htm).
|
||||
|
||||
Public Keys
|
||||
------------
|
||||
|
||||
The GnuPG public key used to sign releases is available in
|
||||
[dist/signingkey.asc](https://github.com/defuse/php-encryption/raw/master/dist/signingkey.asc). Its fingerprint is:
|
||||
|
||||
```
|
||||
2FA6 1D8D 99B9 2658 6BAC 3D53 385E E055 A129 1538
|
||||
```
|
||||
|
||||
You can verify it against the Taylor Hornby's [contact
|
||||
page](https://defuse.ca/contact.htm) and
|
||||
[twitter](https://twitter.com/DefuseSec/status/723741424253059074).

Cryptography Details
|
||||
=====================
|
||||
|
||||
Here is a high-level description of how this library works. Any discrepancy
|
||||
between this documentation and the actual implementation will be considered
|
||||
a security bug.
|
||||
|
||||
Let's start with the following definitions:
|
||||
|
||||
- HKDF-SHA256(*k*, *n*, *info*, *s*) is the key derivation function specified in
|
||||
RFC 5869 (using the SHA256 hash function). The parameters are:
|
||||
- *k*: The initial keying material.
|
||||
- *n*: The number of output bytes.
|
||||
- *info*: The info string.
|
||||
- *s*: The salt.
|
||||
- AES-256-CTR(*m*, *k*, *iv*) is AES-256 encryption in CTR mode. The parameters
|
||||
are:
|
||||
- *m*: An arbitrary-length (possibly zero-length) message.
|
||||
- *k*: A 32-byte key.
|
||||
- *iv*: A 16-byte initialization vector (nonce).
|
||||
- PBKDF2-SHA256(*p*, *s*, *i*, *n*) is the password-based key derivation
|
||||
function defined in RFC 2898 (using the SHA256 hash function). The parameters
|
||||
are:
|
||||
- *p*: The password string.
|
||||
- *s*: The salt string.
|
||||
- *i*: The iteration count.
|
||||
- *n*: The output length in bytes.
|
||||
- VERSION is the string `"\xDE\xF5\x02\x00"`.
|
||||
- AUTHINFO is the string `"DefusePHP|V2|KeyForAuthentication"`.
|
||||
- ENCRINFO is the string `"DefusePHP|V2|KeyForEncryption"`.
|
||||
|
||||
To encrypt a message *m* using a 32-byte key *k*, the following steps are taken:
|
||||
|
||||
1. Generate a random 32-byte string *salt*.
|
||||
2. Derive the 32-byte authentication key *akey* = HKDF-SHA256(*k*, 32, AUTHINFO, *salt*).
|
||||
3. Derive the 32-byte encryption key *ekey* = HKDF-SHA256(*k*, 32, ENCRINFO, *salt*).
|
||||
4. Generate a random 16-byte initialization vector *iv*.
|
||||
5. Compute *c* = AES-256-CTR(*m*, *ekey*, *iv*).
|
||||
6. Combine *ctxt* = VERSION || *salt* || *iv* || *c*.
|
||||
7. Compute *h* = HMAC-SHA256(*ctxt*, *akey*).
|
||||
8. Output *ctxt* || *h*.
|
||||
|
||||
Decryption is roughly the reverse process (see the code for details, since the
|
||||
security of the decryption routine is highly implementation-dependent).
|
||||
|
||||
For encryption using a password *p*, steps 1-3 above are replaced by:
|
||||
|
||||
1. Generate a random 32-byte string *salt*.
|
||||
2. Compute *k* = PBKDF2-SHA256(SHA256(*p*), *salt*, 100000, 32).
|
||||
3. Derive the 32-byte authentication key *akey* = HKDF-SHA256(*k*, 32, AUTHINFO, *salt*)
|
||||
4. Derive the 32-byte encryption key *ekey* = HKDF-SHA256(*k*, 32, ENCRINFO, *salt*)
|
||||
|
||||
The remainder of the process is the same. Notice the reuse of the same *salt*
|
||||
for PBKDF2-SHA256 and HKDF-SHA256. The prehashing of the password in step 2 is
|
||||
done to prevent a [DoS attack using long
|
||||
passwords](https://github.com/defuse/php-encryption/issues/230).
|
||||
|
||||
For `KeyProtectedByPassword`, the serialized key is encrypted according to the
|
||||
password encryption defined above. However, the actual password used for
|
||||
encryption is the SHA256 hash of the password the user provided. This is done in
|
||||
order to provide domain separation between the message encryption in the user's
|
||||
application and the internal key encryption done by this library. It fixes
|
||||
a [key replacement chosen-protocol
|
||||
attack](https://github.com/defuse/php-encryption/issues/240).

Frequently Asked Questions
|
||||
===========================
|
||||
|
||||
How do I use this library to encrypt passwords?
|
||||
------------------------------------------------
|
||||
|
||||
Passwords should not be encrypted, they should be hashed with a *slow* password
|
||||
hashing function that's designed to slow down password guessing attacks. See
|
||||
[How to Safely Store Your Users' Passwords in
|
||||
2016](https://paragonie.com/blog/2016/02/how-safely-store-password-in-2016).
|
||||
|
||||
How do I give it the same key every time instead of a new random key?
|
||||
----------------------------------------------------------------------
|
||||
|
||||
A `Key` object can be saved to a string by calling its `saveToAsciiSafeString()`
|
||||
method. You will have to save that string somewhere safe, and then load it back
|
||||
into a `Key` object using `Key`'s `loadFromAsciiSafeString` static method.
|
||||
|
||||
Where you store the string depends on your application. For example if you are
|
||||
using `KeyProtectedByPassword` to encrypt files with a user's login password,
|
||||
then you should not store the `Key` at all. If you are protecting sensitive data
|
||||
on a server that may be compromised, then you should store it in a hardware
|
||||
security module. When in doubt, consult a security expert.
|
||||
|
||||
Why is an EnvironmentIsBrokenException getting thrown?
|
||||
-------------------------------------------------------
|
||||
|
||||
Either you've encountered a bug in this library, or your system doesn't support
|
||||
the use of this library. For example, if your system does not have a secure
|
||||
random number generator, this library will refuse to run, by throwing that
|
||||
exception, instead of falling back to an insecure random number generator.
|
||||
|
||||
Why am I getting a BadFormatException when loading a Key from a string?
|
||||
------------------------------------------------------------------------
|
||||
|
||||
If you're getting this exception, then the string you're giving to
|
||||
`loadFromAsciiSafeString()` is *not* the same as the string you got from
|
||||
`saveToAsciiSafeString()`. Perhaps your database column isn't wide enough and
|
||||
it's truncating the string as you insert it?

|
|||
Getting The Code
|
||||
=================
|
||||
|
||||
There are two ways to use this library in your applications. You can either:
|
||||
|
||||
1. Use [Composer](https://getcomposer.org/), or
|
||||
2. `require_once` a single `.phar` file in your application.
|
||||
|
||||
If you are not using either option (for example, because you're using Git submodules), you may need to write your own autoloader ([example](https://gist.github.com/paragonie-scott/949daee819bb7f19c50e5e103170b400)).
|
||||
|
||||
Option 1: Using Composer
|
||||
-------------------------
|
||||
|
||||
Run this inside the directory of your composer-enabled project:
|
||||
|
||||
```sh
|
||||
composer require defuse/php-encryption
|
||||
```
|
||||
|
||||
Unfortunately, composer doesn't provide a way for you to verify that the code
|
||||
you're getting was signed by this library's authors. If you want a more secure
|
||||
option, use the `.phar` method described below.
|
||||
|
||||
Option 2: Including a PHAR
|
||||
----------------------------
|
||||
|
||||
The `.phar` option lets you include this library into your project simply by
|
||||
calling `require_once` on a single file. Download `defuse-crypto.phar` and
|
||||
`defuse-crypto.phar.sig` from this project's
|
||||
[releases](https://github.com/defuse/php-encryption/releases) page.
|
||||
|
||||
You should verify the integrity of the `.phar`. The `defuse-crypto.phar.sig`
|
||||
contains the signature of `defuse-crypto.phar`. It is signed with Taylor
|
||||
Hornby's PGP key. You can find Taylor's public key in `dist/signingkey.asc`. You
|
||||
can verify the public key's fingerprint against the Taylor Hornby's [contact
|
||||
page](https://defuse.ca/contact.htm) and
|
||||
[twitter](https://twitter.com/DefuseSec/status/723741424253059074).
|
||||
|
||||
Once you have verified the signature, it is safe to use the `.phar`. Place it
|
||||
somewhere in your file system, e.g. `/var/www/lib/defuse-crypto.phar`, and then
|
||||
pass that path to `require_once`.
|
||||
|
||||
```php
|
||||
<?php
|
||||
|
||||
require_once('/var/www/lib/defuse-crypto.phar');
|
||||
|
||||
// ... the Crypto, File, Key, and KeyProtectedByPassword classes are now
|
||||
// available ...
|
||||
|
||||
// ...
|
||||
```

Information for the Developers of php-encryption
|
||||
=================================================
|
||||
|
||||
Status
|
||||
-------
|
||||
|
||||
This library is currently frozen under a long-term support release. We do not
|
||||
plan to add any new features. We will maintain the library by fixing any bugs
|
||||
that are reported, or security vulnerabilities that are found.
|
||||
|
||||
Development Environment
|
||||
------------------------
|
||||
|
||||
Development is done on Linux. To run the tests, you will need to have the
|
||||
following tools installed:
|
||||
|
||||
- `php` (with OpenSSL enabled, if you're compiling from source).
|
||||
- `gpg`
|
||||
- `composer`
|
||||
|
||||
Running the Tests
|
||||
------------------
|
||||
|
||||
First do `composer install` and then you can run the tests by running
|
||||
`./test.sh`. This will download a PHPUnit PHAR, verify its cryptographic
|
||||
signatures, and then use it to run the tests in `test/unit`.
|
||||
|
||||
Getting and Using Psalm
|
||||
-----------------------
|
||||
|
||||
[Psalm](https://github.com/vimeo/psalm) is a static analysis suite for PHP projects.
|
||||
We use Psalm to ensure type safety throughout our library.
|
||||
|
||||
To install Psalm, you just need to run one command:
|
||||
|
||||
composer require --dev "vimeo/psalm:dev-master"
|
||||
|
||||
To verify that your code changes are still strictly type-safe, run the following
|
||||
command:
|
||||
|
||||
vendor/bin/psalm
|
||||
|
||||
Reporting Bugs
|
||||
---------------
|
||||
|
||||
Please report bugs, even critical security vulnerabilities, by opening an issue
|
||||
on GitHub. We recommend disclosing security vulnerabilities found in this
|
||||
library *publicly* as soon as possible.
|
||||
|
||||
Philosophy
|
||||
-----------
|
||||
|
||||
This library is developed around several core values:
|
||||
|
||||
- Rule #1: Security is prioritized over everything else.
|
||||
|
||||
> Whenever there is a conflict between security and some other property,
|
||||
> security will be favored. For example, the library has runtime tests,
|
||||
> which make it slower, but will hopefully stop it from encrypting stuff
|
||||
> if the platform it's running on is broken.
|
||||
|
||||
- Rule #2: It should be difficult to misuse the library.
|
||||
|
||||
> We assume the developers using this library have no experience with
|
||||
> cryptography. We only assume that they know that the "key" is something
|
||||
> you need to encrypt and decrypt the messages, and that it must be kept
|
||||
> secret. Whenever possible, the library should refuse to encrypt or decrypt
|
||||
> messages when it is not being used correctly.
|
||||
|
||||
- Rule #3: The library aims only to be compatible with itself.
|
||||
|
||||
> Other PHP encryption libraries try to support every possible type of
|
||||
> encryption, even the insecure ones (e.g. ECB mode). Because there are so
|
||||
> many options, inexperienced developers must decide whether to use "CBC
|
||||
> mode" or "ECB mode" when both are meaningless terms to them. This
|
||||
> inevitably leads to vulnerabilities.
|
||||
|
||||
> This library will only support one secure mode. A developer using this
|
||||
> library will call "encrypt" and "decrypt" methods without worrying about
|
||||
> how they are implemented.
|
||||
|
||||
- Rule #4: The library should require no special installation.
|
||||
|
||||
> Some PHP encryption libraries, like libsodium-php, are not straightforward
|
||||
> to install and cannot packaged with "just download and extract"
|
||||
> applications. This library will always be just a handful of PHP files that
|
||||
> you can copy to your source tree and require().
|
||||
|
||||
Publishing Releases
|
||||
--------------------
|
||||
|
||||
To make a release, you will need to install [composer](https://getcomposer.org/)
|
||||
and [box](https://github.com/box-project/box2) on your system. They will need to
|
||||
be available in your `$PATH` so that running the commands `composer` and `box`
|
||||
in your terminal run them, respectively. You will also need the private key for
|
||||
signing (ID: 7B4B2D98) available.
|
||||
|
||||
Once you have those tools installed and the key available follow these steps:
|
||||
|
||||
**Remember to set the version number in `composer.json`!**
|
||||
|
||||
Make a fresh clone of the repository:
|
||||
|
||||
```
|
||||
git clone <url>
|
||||
```
|
||||
|
||||
Check out the branch you want to release:
|
||||
|
||||
```
|
||||
git checkout <branchname>
|
||||
```
|
||||
|
||||
Check that the version number in composer.json is correct:
|
||||
|
||||
```
|
||||
cat composer.json
|
||||
```
|
||||
|
||||
Run the tests:
|
||||
|
||||
```
|
||||
composer install
|
||||
./test.sh
|
||||
```
|
||||
|
||||
Generate the `.phar`:
|
||||
|
||||
```
|
||||
cd dist
|
||||
make build-phar
|
||||
```
|
||||
|
||||
Test the `.phar`:
|
||||
|
||||
```
|
||||
cd ../
|
||||
./test.sh dist/defuse-crypto.phar
|
||||
```
|
||||
|
||||
Sign the `.phar`:
|
||||
|
||||
```
|
||||
cd dist
|
||||
make sign-phar
|
||||
```
|
||||
|
||||
Tag the release:
|
||||
|
||||
```
|
||||
git -c user.signingkey=7B4B2D98 tag -s "<TAG NAME>" -m "<TAG MESSAGE>"
|
||||
```
|
||||
|
||||
`<TAG NAME>` should be in the format `v2.0.0` and `<TAG MESSAGE>` should look
|
||||
like "Release of v2.0.0."
|
||||
|
||||
Push the tag to github, then use the
|
||||
[releases](https://github.com/defuse/php-encryption/releases) page to draft
|
||||
a new release for that tag. Upload the `.phar` and the `.phar.sig` file to be
|
||||
included as part of that release.

Tutorial
|
||||
=========
|
||||
|
||||
Hello! If you're reading this file, it's because you want to add encryption to
|
||||
one of your PHP projects. My job, as the person writing this documentation, is
|
||||
to help you make sure you're doing the right thing and then show you how to use
|
||||
this library to do it. To help me help you, please read the documentation
|
||||
*carefully* and *deliberately*.
|
||||
|
||||
A Word of Caution
|
||||
------------------
|
||||
|
||||
Encryption is not magic dust you can sprinkle on a system to make it more
|
||||
secure. The way encryption is integrated into a system's design needs to be
|
||||
carefully thought out. Sometimes, encryption is the wrong thing to use. Other
|
||||
times, encryption needs to be used in a very specific way in order for it to
|
||||
work as intended. Even if you are sure of what you are doing, we strongly
|
||||
recommend seeking advice from an expert.
|
||||
|
||||
The first step is to think about your application's threat model. Ask yourself
|
||||
the following questions. Who will want to attack my application, and what will
|
||||
they get out of it? Are they trying to steal some information? Trying to alter
|
||||
or destroy some information? Or just trying to make the system go down so people
|
||||
can't access it? Then ask yourself how encryption can help combat those threats.
|
||||
If you're going to add encryption to your application, you should have a very
|
||||
clear idea of exactly which kinds of attacks it's helping to secure your
|
||||
application against. Once you have your threat model, think about what kinds of
|
||||
attacks it *does not* cover, and whether or not you should improve your threat
|
||||
model to include those attacks.
|
||||
|
||||
**This isn't for storing user login passwords:** The most common use of
|
||||
cryptography in web applications is to protect the users' login passwords. If
|
||||
you're trying to use this library to "encrypt" your users' passwords, you're in
|
||||
the wrong place. Passwords shouldn't be *encrypted*, they should be *hashed*
|
||||
with a slow computation-heavy function that makes password guessing attacks more
|
||||
expensive. See [How to Safely Store Your Users' Passwords in
|
||||
2016](https://paragonie.com/blog/2016/02/how-safely-store-password-in-2016).
|
||||
|
||||
**This isn't for encrypting network communication:** Likewise, if you're trying
|
||||
to encrypt messages sent between two parties over the Internet, you don't want
|
||||
to be using this library. For that, set up a TLS connection between the two
|
||||
points, or, if it's a chat app, use the [Signal
|
||||
Protocol](https://whispersystems.org/blog/advanced-ratcheting/).
|
||||
|
||||
What this library provides is symmetric encryption for "data at rest." This
|
||||
means it is not suitable for use in building protocols where "data is in motion"
|
||||
(i.e. moving over a network) except in limited set of cases.
|
||||
|
||||
Getting the Code
|
||||
-----------------
|
||||
|
||||
There are several different ways to obtain this library's code and to add it to
|
||||
your project. Even if you've already cloned the code from GitHub, you should
|
||||
take steps to verify the cryptographic signatures to make sure the code you got
|
||||
was not intercepted and modified by an attacker.
|
||||
|
||||
Please head over to the [**Installing and
|
||||
Verifying**](InstallingAndVerifying.md) documentation to get the code, and then
|
||||
come back here to continue the tutorial.
|
||||
|
||||
Using the Library
|
||||
------------------
|
||||
|
||||
I'm going to assume you know what symmetric encryption is, and the difference
|
||||
between symmetric and asymmetric encryption. If you don't, I recommend taking
|
||||
[Dan Boneh's Cryptography I course](https://www.coursera.org/learn/crypto/) on
|
||||
Coursera.
|
||||
|
||||
To give you a quick introduction to the library, I'm going to explain how it
|
||||
would be used in two sterotypical scenarios. Hopefully, one of these sterotypes
|
||||
is close enough to what you want to do that you'll be able to figure out what
|
||||
needs to be different on your own.

||||

|
||||
|
||||
While this tutorial should get you up and running fast, it's important to
|
||||
understand how this library behaves. Please make sure to read the formal
|
||||
documentation of all of the functions you're using, since there are some
|
||||
important security warnings there.
|
||||
|
||||
The following classes are available for you to use:
|
||||
|
||||
- [Crypto](classes/Crypto.md): Encrypting and decrypting strings.
|
||||
- [File](classes/File.md): Encrypting and decrypting files.
|
||||
- [Key](classes/Key.md): Represents a secret encryption key.
|
||||
- [KeyProtectedByPassword](classes/KeyProtectedByPassword.md): Represents
|
||||
a secret encryption key that needs to be "unlocked" by a password before it
|
||||
can be used.
|
||||
|
||||
### Scenario #1: Keep data secret from the database administrator
|
||||
|
||||
In this scenario, our threat model is as follows. Alice is a server
|
||||
administrator responsible for managing a trusted web server. Eve is a database
|
||||
administrator responsible for managing a database server. Dave is a web
|
||||
developer working on code that will eventually run on the trusted web server.
|
||||
|
||||
Let's say Alice and Dave trust each other, and Alice is going to host Dave's
|
||||
application on her server. But both Alice and Dave don't trust Eve. They know
|
||||
Eve is a good database administrator, but she might have incentive to steal the
|
||||
data from the database. They want to keep some of the web application's data
|
||||
secret from Eve.
|
||||
|
||||
In order to do that, Alice will use the included `generate-defuse-key` script
|
||||
which generates a random encryption key and prints it to standard output:
|
||||
|
||||
```sh
|
||||
$ composer require defuse/php-encryption
|
||||
$ vendor/bin/generate-defuse-key
|
||||
```
|
||||
|
||||
Alice will run this script once and save the output to a configuration file, say
|
||||
in `/etc/daveapp-secret-key.txt` and set the file permissions so that only the
|
||||
user that the website PHP scripts run as can access it.
|
||||
|
||||
Dave will write his code to load the key from the configuration file:
|
||||
|
||||
```php
|
||||
<?php
|
||||
use Defuse\Crypto\Key;
|
||||
|
||||
function loadEncryptionKeyFromConfig()
|
||||
{
|
||||
$keyAscii = // ... load the contents of /etc/daveapp-secret-key.txt
|
||||
return Key::loadFromAsciiSafeString($keyAscii);
|
||||
}
|
||||
```
|
||||
|
||||
Then, whenever Dave wants to save a secret value to the database, he will first
|
||||
encrypt it:
|
||||
|
||||
```php
|
||||
<?php
|
||||
use Defuse\Crypto\Crypto;
|
||||
|
||||
// ...
|
||||
$key = loadEncryptionKeyFromConfig();
|
||||
// ...
|
||||
$ciphertext = Crypto::encrypt($secret_data, $key);
|
||||
// ... save $ciphertext into the database ...
|
||||
```
|
||||
|
||||
Whenever Dave wants to get the value back from the database, he must decrypt it
|
||||
using the same key:
|
||||
|
||||
```php
|
||||
<?php
|
||||
use Defuse\Crypto\Crypto;
|
||||
|
||||
// ...
|
||||
$key = loadEncryptionKeyFromConfig();
|
||||
// ...
|
||||
$ciphertext = // ... load $ciphertext from the database
|
||||
try {
|
||||
$secret_data = Crypto::decrypt($ciphertext, $key);
|
||||
} catch (\Defuse\Crypto\Exception\WrongKeyOrModifiedCiphertextException $ex) {
|
||||
// An attack! Either the wrong key was loaded, or the ciphertext has
|
||||
// changed since it was created -- either corrupted in the database or
|
||||
// intentionally modified by Eve trying to carry out an attack.
|
||||
|
||||
// ... handle this case in a way that's suitable to your application ...
|
||||
}
|
||||
```
|
||||
|
||||
Note that if anyone ever steals the key from Alice's server, they can decrypt
|
||||
all of the ciphertexts that are stored in the database. As part of our threat
|
||||
model, we are assuming Alice's server administration skills and Dave's secure
|
||||
coding skills are good enough to stop Eve from being able to steal the key.
|
||||
Under those assumptions, this solution will prevent Eve from seeing data that's
|
||||
stored in the database.
|
||||
|
||||
However, notice that our threat model says nothing about what could happen if
|
||||
Eve wants to *modify* the data. With this solution, Eve will not be able to
|
||||
alter any individual ciphertext (because each ciphertext has its own
|
||||
cryptographic integrity check), but Eve *will* be able to swap ciphertexts for
|
||||
one another, and revert ciphertexts to what they used to be at previous times.
|
||||
If we needed to defend against such attacks, we would have to re-design our
|
||||
threat model and come up with a different solution.
|
||||
|
||||
### Scenario #2: Encrypting account data with the user's login password
|
||||
|
||||
This scenario is like Scenario 1, but subtly different. The threat model is as
|
||||
follows. We have Alice, a server administrator, and Dave, the developer. Alice
|
||||
and Dave trust each other, and Alice wants to host Dave's web application,
|
||||
including its database, on her server. Alice is worried about her server getting
|
||||
hacked. The application will store the users' credit card numbers, and Alice
|
||||
wants to protect them in case the server gets hacked.
|
||||
|
||||
We can model the situation like this: after the server gets hacked, the attacker
|
||||
will have read and write access to all data on it until the attack is detected
|
||||
and Alice rebuilds the server. We'll call the time the attacker has access to
|
||||
the server the *exposure window.* One idea to minimize loss is to encrypt the
|
||||
users' credit card numbers using a key made from their login password. Then, as
|
||||
long as the users all have strong passwords, and they are never logged in during
|
||||
the exposure window, their credit cards will be protected from the attacker.
|
||||
|
||||
To implement this, Dave will use the `KeyProtectedByPassword` class. When a new
|
||||
user account is created, Dave will save a new key to their account, one that's
|
||||
protected by their login password:
|
||||
|
||||
```php
|
||||
<?php
|
||||
use Defuse\Crypto\KeyProtectedByPassword;
|
||||
|
||||
function CreateUserAccount($username, $password)
|
||||
{
|
||||
// ... other user account creation stuff, including password hashing
|
||||
|
||||
$protected_key = KeyProtectedByPassword::createRandomPasswordProtectedKey($password);
|
||||
$protected_key_encoded = $protected_key->saveToAsciiSafeString();
|
||||
// ... save $protected_key_encoded into the user's account record
|
||||
}
|
||||
```
|
||||
|
||||
Then, when the user logs in, Dave's code will load the protected key from the
|
||||
user's account record, unlock it to get a `Key` object, and save the `Key`
|
||||
object somewhere safe (like temporary memory-backed session storage). Note that
|
||||
wherever Dave's code saves the key, it must be destroyed once the user logs out,
|
||||
or else the attacker might be able to find users' keys even if they were never
|
||||
logged in during the attack.
|
||||
|
||||
```php
|
||||
<?php
|
||||
use Defuse\Crypto\KeyProtectedByPassword;
|
||||
|
||||
// ... authenticate the user using a good password hashing scheme
|
||||
// keep the user's password in $password
|
||||
|
||||
$protected_key_encoded = // ... load it from the user's account record
|
||||
$protected_key = KeyProtectedByPassword::loadFromAsciiSafeString($protected_key_encoded);
|
||||
$user_key = $protected_key->unlockKey($password);
|
||||
$user_key_encoded = $user_key->saveToAsciiSafeString();
|
||||
// ... save $user_key_encoded in the session
|
||||
```
|
||||
|
||||
```php
|
||||
<?php
|
||||
// ... when the user is logging out ...
|
||||
// ... securely wipe the saved $user_key_encoded from the system ...
|
||||
```
|
||||
|
||||
When a user adds their credit card number, Dave's code will get the key from the
|
||||
session and use it to encrypt the credit card number:
|
||||
|
||||
```php
|
||||
<?php
|
||||
use Defuse\Crypto\Crypto;
|
||||
use Defuse\Crypto\Key;
|
||||
|
||||
// ...
|
||||
|
||||
$user_key_encoded = // ... get it out of the session ...
|
||||
$user_key = Key::loadFromAsciiSafeString($user_key_encoded);
|
||||
|
||||
// ...
|
||||
|
||||
$credit_card_number = // ... get credit card number from the user
|
||||
$encrypted_card_number = Crypto::encrypt($credit_card_number, $user_key);
|
||||
// ... save $encrypted_card_number in the database
|
||||
```
|
||||
|
||||
When the application needs to use the credit card number, it will decrypt it:
|
||||
|
||||
```php
|
||||
<?php
|
||||
use Defuse\Crypto\Crypto;
|
||||
use Defuse\Crypto\Key;
|
||||
|
||||
// ...
|
||||
|
||||
$user_key_encoded = // ... get it out of the session
|
||||
$user_key = Key::loadFromAsciiSafeString($user_key_encoded);
|
||||
|
||||
// ...
|
||||
|
||||
$encrypted_card_number = // ... load it from the database ...
|
||||
try {
|
||||
$credit_card_number = Crypto::decrypt($encrypted_card_number, $user_key);
|
||||
} catch (Defuse\Crypto\Exception\WrongKeyOrModifiedCiphertextException $ex) {
|
||||
// Either there's a bug in our code, we're trying to decrypt with the
|
||||
// wrong key, or the encrypted credit card number was corrupted in the
|
||||
// database.
|
||||
|
||||
// ... handle this case ...
|
||||
}
|
||||
```
|
||||
|
||||
With all caveats carefully heeded, this solution limits credit card number
|
||||
exposure in the case where Alice's server gets hacked for a short amount of
|
||||
time. Remember to think about the attacks that *aren't* included in our threat
|
||||
model. The attacker is still free to do all sorts of harmful things like
|
||||
modifying the server's data which may go undetected if Alice doesn't have secure
|
||||
backups to compare against.

Upgrading From Version 1.2
|
||||
===========================
|
||||
|
||||
With version 2.0.0 of this library came major changes to the ciphertext format,
|
||||
algorithms used for encryption, and API.
|
||||
|
||||
In version 1.2, keys were represented by 16-byte string variables. In version
|
||||
2.0.0, keys are represented by objects, instances of the `Key` class. This
|
||||
change was made in order to make it harder to misuse the API. For example, in
|
||||
version 1.2, you could pass in *any* 16-byte string, but in version 2.0.0 you
|
||||
need a `Key` object, which you can only get if you're "doing the right thing."
|
||||
|
||||
This means that for all of your old version 1.2 keys, you'll have to:
|
||||
|
||||
1. Generate a new version 2.0.0 key.
|
||||
2. For all of the ciphertexts encrypted under the old key:
|
||||
1. Decrypt the ciphertext using the old version 1.2 key.
|
||||
2. Re-encrypt it using the new version 2.0.0 key.
|
||||
|
||||
Use the special `Crypto::legacyDecrypt()` method to decrypt the old ciphertexts
|
||||
using the old key and then re-encrypt them using `Crypto::encrypt()` with the
|
||||
new key. Your code will look something like the following. To avoid data loss,
|
||||
securely back up your keys and data before running your upgrade code.
|
||||
|
||||
```php
|
||||
<?php
|
||||
|
||||
// ...
|
||||
|
||||
$legacy_ciphertext = // ... get the ciphertext you want to upgrade ...
|
||||
$legacy_key = // ... get the key to decrypt this ciphertext ...
|
||||
|
||||
// Generate the new key that we'll re-encrypt the ciphertext with.
|
||||
$new_key = Key::createNewRandomKey();
|
||||
// ... save it somewhere ...
|
||||
|
||||
// Decrypt it.
|
||||
try {
|
||||
$plaintext = Crypto::legacyDecrypt($legacy_ciphertext, $legacy_key);
|
||||
} catch (Defuse\Crypto\Exception\WrongKeyOrModifiedCiphertextException $ex)
|
||||
{
|
||||
// ... TODO: handle this case appropriately ...
|
||||
}
|
||||
|
||||
// Re-encrypt it.
|
||||
$new_ciphertext = Crypto::encrypt($plaintext, $new_key);
|
||||
|
||||
// ... replace the old $legacy_ciphertext with the new $new_ciphertext
|
||||
|
||||
// ...

Class: Defuse\Crypto\Crypto
|
||||
============================
|
||||
|
||||
The `Crypto` class provides encryption and decryption of strings either using
|
||||
a secret key or secret password. For encryption and decryption of large files,
|
||||
see the `File` class.
|
||||
|
||||
This code for this class is in `src/Crypto.php`.
|
||||
|
||||
Instance Methods
|
||||
-----------------
|
||||
|
||||
This class has no instance methods.
|
||||
|
||||
Static Methods
|
||||
---------------
|
||||
|
||||
### Crypto::encrypt($plaintext, Key $key, $raw\_binary = false)
|
||||
|
||||
**Description:**
|
||||
|
||||
Encrypts a plaintext string using a secret key.
|
||||
|
||||
**Parameters:**
|
||||
|
||||
1. `$plaintext` is the string to encrypt.
|
||||
2. `$key` is an instance of `Key` containing the secret key for encryption.
|
||||
3. `$raw_binary` determines whether the output will be a byte string (true) or
|
||||
hex encoded (false, the default).
|
||||
|
||||
**Return value:**
|
||||
|
||||
Returns a ciphertext string representing `$plaintext` encrypted with the key
|
||||
`$key`. Knowledge of `$key` is required in order to decrypt the ciphertext and
|
||||
recover the plaintext.
|
||||
|
||||
**Exceptions:**
|
||||
|
||||
- `Defuse\Crypto\Exception\EnvironmentIsBrokenException` is thrown either when
|
||||
the platform the code is running on cannot safely perform encryption for some
|
||||
reason (e.g. it lacks a secure random number generator), or the runtime tests
|
||||
detected a bug in this library.
|
||||
|
||||
**Side-effects and performance:**
|
||||
|
||||
This method runs a small and very fast set of self-tests if it is the very first
|
||||
time one of the `Crypto` methods has been called. The performance overhead is
|
||||
negligible and can be safely ignored in all applications.
|
||||
|
||||
**Cautions:**
|
||||
|
||||
The ciphertext returned by this method is decryptable by anyone with knowledge
|
||||
of the key `$key`. It is the caller's responsibility to keep `$key` secret.
|
||||
Where `$key` should be stored is up to the caller and depends on the threat
|
||||
model the caller is designing their application under. If you are unsure where
|
||||
to store `$key`, consult with a professional cryptographer to get help designing
|
||||
your application.
|
||||
|
||||
### Crypto::decrypt($ciphertext, Key $key, $raw\_binary = false)
|
||||
|
||||
**Description:**
|
||||
|
||||
Decrypts a ciphertext string using a secret key.
|
||||
|
||||
**Parameters:**
|
||||
|
||||
1. `$ciphertext` is the ciphertext to be decrypted.
|
||||
2. `$key` is an instance of `Key` containing the secret key for decryption.
|
||||
3. `$raw_binary` must have the same value as the `$raw_binary` given to the
|
||||
call to `encrypt()` that generated `$ciphertext`.
|
||||
|
||||
**Return value:**
|
||||
|
||||
If the decryption succeeds, returns a string containing the same value as the
|
||||
string that was passed to `encrypt()` when `$ciphertext` was produced. Upon
|
||||
a successful return, the caller can be assured that `$ciphertext` could not have
|
||||
been produced except by someone with knowledge of `$key`.
|
||||
|
||||
**Exceptions:**
|
||||
|
||||
- `Defuse\Crypto\Exception\EnvironmentIsBrokenException` is thrown either when
|
||||
the platform the code is running on cannot safely perform encryption for some
|
||||
reason (e.g. it lacks a secure random number generator), or the runtime tests
|
||||
detected a bug in this library.
|
||||
|
||||
- `Defuse\Crypto\Exception\WrongKeyOrModifiedCiphertextException` is thrown if
|
||||
the `$key` is not the correct key for the given ciphertext, or if the
|
||||
ciphertext has been modified (possibly maliciously). There is no way to
|
||||
distinguish between these two cases.
|
||||
|
||||
**Side-effects and performance:**
|
||||
|
||||
This method runs a small and very fast set of self-tests if it is the very first
|
||||
time one of the `Crypto` methods has been called. The performance overhead is
|
||||
negligible and can be safely ignored in all applications.
|
||||
|
||||
**Cautions:**
|
||||
|
||||
It is impossible in principle to distinguish between the case where you attempt
|
||||
to decrypt with the wrong key and the case where you attempt to decrypt
|
||||
a modified (corrupted) ciphertext. It is up to the caller how to best deal with
|
||||
this ambiguity, as it depends on the application this library is being used in.
|
||||
If in doubt, consult with a professional cryptographer.
|
||||
|
||||
### Crypto::encryptWithPassword($plaintext, $password, $raw\_binary = false)
|
||||
|
||||
**Description:**
|
||||
|
||||
Encrypts a plaintext string using a secret password.
|
||||
|
||||
**Parameters:**
|
||||
|
||||
1. `$plaintext` is the string to encrypt.
|
||||
2. `$password` is a string containing the secret password used for encryption.
|
||||
3. `$raw_binary` determines whether the output will be a byte string (true) or
|
||||
hex encoded (false, the default).
|
||||
|
||||
**Return value:**
|
||||
|
||||
Returns a ciphertext string representing `$plaintext` encrypted with a key
|
||||
derived from `$password`. Knowledge of `$password` is required in order to
|
||||
decrypt the ciphertext and recover the plaintext.
|
||||
|
||||
**Exceptions:**
|
||||
|
||||
- `Defuse\Crypto\Exception\EnvironmentIsBrokenException` is thrown either when
|
||||
the platform the code is running on cannot safely perform encryption for some
|
||||
reason (e.g. it lacks a secure random number generator), or the runtime tests
|
||||
detected a bug in this library.
|
||||
|
||||
**Side-effects and performance:**
|
||||
|
||||
This method is intentionally slow, using a lot of CPU resources for a fraction
|
||||
of a second. It applies key stretching to the password in order to make password
|
||||
guessing attacks more computationally expensive. If you need a faster way to
|
||||
encrypt multiple ciphertexts under the same password, see the
|
||||
`KeyProtectedByPassword` class.
|
||||
|
||||
This method runs a small and very fast set of self-tests if it is the very first
|
||||
time one of the `Crypto` methods has been called. The performance overhead is
|
||||
negligible and can be safely ignored in all applications.
|
||||
|
||||
**Cautions:**
|
||||
|
||||
PHP stack traces display (portions of) the arguments passed to methods on the
|
||||
call stack. If an exception is thrown inside this call, and it is uncaught, the
|
||||
value of `$password` may be leaked out to an attacker through the stack trace.
|
||||
We recommend configuring PHP to never output stack traces (either displaying
|
||||
them to the user or saving them to log files).
|
||||
|
||||
### Crypto::decryptWithPassword($ciphertext, $password, $raw\_binary = false)
|
||||
|
||||
**Description:**
|
||||
|
||||
Decrypts a ciphertext string using a secret password.
|
||||
|
||||
**Parameters:**
|
||||
|
||||
1. `$ciphertext` is the ciphertext to be decrypted.
|
||||
2. `$password` is a string containing the secret password used for decryption.
|
||||
3. `$raw_binary` must have the same value as the `$raw_binary` given to the
|
||||
call to `encryptWithPassword()` that generated `$ciphertext`.
|
||||
|
||||
**Return value:**
|
||||
|
||||
If the decryption succeeds, returns a string containing the same value as the
|
||||
string that was passed to `encryptWithPassword()` when `$ciphertext` was
|
||||
produced. Upon a successful return, the caller can be assured that `$ciphertext`
|
||||
could not have been produced except by someone with knowledge of `$password`.
|
||||
|
||||
**Exceptions:**
|
||||
|
||||
- `Defuse\Crypto\Exception\EnvironmentIsBrokenException` is thrown either when
|
||||
the platform the code is running on cannot safely perform encryption for some
|
||||
reason (e.g. it lacks a secure random number generator), or the runtime tests
|
||||
detected a bug in this library.
|
||||
|
||||
- `Defuse\Crypto\Exception\WrongKeyOrModifiedCiphertextException` is thrown if
|
||||
the `$password` is not the correct password for the given ciphertext, or if
|
||||
the ciphertext has been modified (possibly maliciously). There is no way to
|
||||
distinguish between these two cases.
|
||||
|
||||
**Side-effects:**
|
||||
|
||||
This method is intentionally slow. It applies key stretching to the password in
|
||||
order to make password guessing attacks more computationally expensive. If you
|
||||
need a faster way to encrypt multiple ciphertexts under the same password, see
|
||||
the `KeyProtectedByPassword` class.
|
||||
|
||||
This method runs a small and very fast set of self-tests if it is the very first
|
||||
time one of the `Crypto` methods has been called. The performance overhead is
|
||||
negligible and can be safely ignored in all applications.
|
||||
|
||||
**Cautions:**
|
||||

call stack. If an exception is thrown inside this call, and it is uncaught, the

value of `$password` may be leaked out to an attacker through the stack trace.

them to the user or saving them to log files).

It is impossible in principle to distinguish between the case where you attempt

### Crypto::legacyDecrypt($ciphertext, $key)
|
||||
|
||||
**Description:**
|
||||
|
||||
Decrypts a ciphertext produced by version 1 of this library so that the
|
||||
plaintext can be re-encrypted into a version 2 ciphertext. See [Upgrading from
|
||||
v1.2](../UpgradingFromV1.2.md).
|
||||
|
||||
**Parameters:**
|
||||
|
||||
1. `$ciphertext` is a ciphertext produced by version 1.x of this library.
|
||||
2. `$key` is a 16-byte string (*not* a Key object) containing the key that was
|
||||
used with version 1.x of this library to produce `$ciphertext`.
|
||||
|
||||
**Return value:**
|
||||
|
||||
If the decryption succeeds, returns the string that was encrypted to make
|
||||
`$ciphertext` by version 1.x of this library. Upon a successful return, the
|
||||
caller can be assured that `$ciphertext` could not have been produced except by
|
||||
someone with knowledge of `$key`.
|
||||
|
||||
**Exceptions:**
|
||||
|
||||
- `Defuse\Crypto\Exception\EnvironmentIsBrokenException` is thrown either when
|
||||
the platform the code is running on cannot safely perform encryption for some
|
||||
reason (e.g. it lacks a secure random number generator), or the runtime tests
|
||||
detected a bug in this library.
|
||||
|
||||
- `Defuse\Crypto\Exception\WrongKeyOrModifiedCiphertextException` is thrown if
|
||||
the `$key` is not the correct key for the given ciphertext, or if the
|
||||
ciphertext has been modified (possibly maliciously). There is no way to
|
||||
distinguish between these two cases.
|
||||
|
||||
**Side-effects:**
|
||||
|
||||
This method runs a small and very fast set of self-tests if it is the very first
|
||||
time one of the `Crypto` methods has been called. The performance overhead is
|
||||
negligible and can be safely ignored in all applications.
|
||||
|
||||
**Cautions:**
|
||||
|
||||
PHP stack traces display (portions of) the arguments passed to methods on the
|
||||
call stack. If an exception is thrown inside this call, and it is uncaught, the
|
||||
value of `$key` may be leaked out to an attacker through the stack trace. We
|
||||
recommend configuring PHP to never output stack traces (either displaying them
|
||||
to the user or saving them to log files).
|
||||

|

|
||||

|
||||
this ambiguity, as it depends on the application this library is being used in.

||||

### File::encryptFile($inputFilename, $outputFilename, Key $key)
|
||||
|
||||
**Description:**
|
||||
|
||||
Encrypts a file using a secret key.
|
||||
|
||||
**Parameters:**
|
||||
|
||||
1. `$inputFilename` is the path to a file containing the plaintext to encrypt.
|
||||
2. `$outputFilename` is the path to save the ciphertext file.
|
||||
3. `$key` is an instance of `Key` containing the secret key for encryption.
|
||||
|
||||
**Behavior:**
|
||||
|
||||
Encrypts the contents of the input file, writing the result to the output file.
|
||||
If the output file already exists, it is overwritten.
|
||||
|
||||
**Return value:**
|
||||
|
||||
Does not return a value.
|
||||
|
||||
**Exceptions:**
|
||||
|
||||
- `Defuse\Crypto\Exception\IOException` is thrown if there is an I/O error.
|
||||
|
||||
- `Defuse\Crypto\Exception\EnvironmentIsBrokenException` is thrown either when
|
||||
the platform the code is running on cannot safely perform encryption for some
|
||||
reason (e.g. it lacks a secure random number generator), or the runtime tests
|
||||
detected a bug in this library.
|
||||
|
||||
**Side-effects and performance:**
|
||||
|
||||
None.
|
||||
|
||||
**Cautions:**
|
||||
|
||||
The ciphertext output by this method is decryptable by anyone with knowledge of
|
||||
the key `$key`. It is the caller's responsibility to keep `$key` secret. Where
|
||||
`$key` should be stored is up to the caller and depends on the threat model the
|
||||
caller is designing their application under. If you are unsure where to store
|
||||
`$key`, consult with a professional cryptographer to get help designing your
|
||||
application.

||||
|
||||
### File::decryptFile($inputFilename, $outputFilename, Key $key)
|
||||
|
||||
**Description:**
|
||||
|
||||
Decrypts a file using a secret key.
|
||||
|
||||
**Parameters:**
|
||||
|
||||
1. `$inputFilename` is the path to a file containing the ciphertext to decrypt.
|
||||
2. `$outputFilename` is the path to save the decrypted plaintext file.
|
||||
3. `$key` is an instance of `Key` containing the secret key for decryption.
|
||||
|
||||
**Behavior:**
|
||||
|
||||
Decrypts the contents of the input file, writing the result to the output file.
|
||||
If the output file already exists, it is overwritten.
|
||||
|
||||
**Return value:**
|
||||
|
||||
Does not return a value.
|
||||
|
||||
**Exceptions:**
|
||||
|
||||
- `Defuse\Crypto\Exception\IOException` is thrown if there is an I/O error.
|
||||
|
||||
- `Defuse\Crypto\Exception\EnvironmentIsBrokenException` is thrown either when
|
||||
the platform the code is running on cannot safely perform encryption for some
|
||||
reason (e.g. it lacks a secure random number generator), or the runtime tests
|
||||
detected a bug in this library.
|
||||
|
||||
- `Defuse\Crypto\Exception\WrongKeyOrModifiedCiphertextException` is thrown if
|
||||
the `$key` is not the correct key for the given ciphertext, or if the
|
||||
ciphertext has been modified (possibly maliciously). There is no way to
|
||||
distinguish between these two cases.
|
||||
|
||||
**Side-effects and performance:**
|
||||
|
||||
The input ciphertext is processed in two passes. The first pass verifies the
|
||||
integrity and the second pass performs the actual decryption of the file and
|
||||
writing to the output file. This is done in a streaming manner so that only
|
||||
a small part of the file is ever loaded into memory at a time.
|
||||
|
||||
**Cautions:**
|
||||
|
||||
Be aware that when `Defuse\Crypto\WrongKeyOrModifiedCiphertextException` is
|
||||
thrown, some partial plaintext data may have been written to the output. Any
|
||||
plaintext data that is output is guaranteed to be a prefix of the original
|
||||
plaintext (i.e. at worst it was truncated). This can only happen if an attacker
|
||||
modifies the input between the first pass (integrity check) and the second pass
|
||||
(decryption) over the file.
|
||||
|
||||
It is impossible in principle to distinguish between the case where you attempt
|
||||
to decrypt with the wrong key and the case where you attempt to decrypt
|
||||
a modified (corrupted) ciphertext. It is up to the caller how to best deal with
|
||||
this ambiguity, as it depends on the application this library is being used in.
|
||||
If in doubt, consult with a professional cryptographer.
|
||||
|
||||
### File::encryptFileWithPassword($inputFilename, $outputFilename, $password)
|
||||
|
||||
**Description:**
|
||||
|
||||
Encrypts a file with a password.
|
||||
|
||||
**Parameters:**
|
||||
|
||||
1. `$inputFilename` is the path to a file containing the plaintext to encrypt.
|
||||
2. `$outputFilename` is the path to save the ciphertext file.
|
||||
3. `$password` is the password used for decryption.
|
||||
|
||||
**Behavior:**
|
||||
|
||||
Encrypts the contents of the input file, writing the result to the output file.
|
||||
If the output file already exists, it is overwritten.
|
||||
|
||||
**Return value:**
|
||||
|
||||
Does not return a value.
|
||||
|
||||
**Exceptions:**
|
||||
|
||||
- `Defuse\Crypto\Exception\IOException` is thrown if there is an I/O error.
|
||||
|
||||
- `Defuse\Crypto\Exception\EnvironmentIsBrokenException` is thrown either when
|
||||
the platform the code is running on cannot safely perform encryption for some
|
||||
reason (e.g. it lacks a secure random number generator), or the runtime tests
|
||||
detected a bug in this library.
|
||||
|
||||
**Side-effects and performance:**
|
||||
|
||||
This method is intentionally slow, using a lot of CPU resources for a fraction
|
||||
of a second. It applies key stretching to the password in order to make password
|
||||
guessing attacks more computationally expensive. If you need a faster way to
|
||||
encrypt multiple ciphertexts under the same password, see the
|
||||
`KeyProtectedByPassword` class.
|
||||
|
||||
**Cautions:**
|
||||
|
||||
PHP stack traces display (portions of) the arguments passed to methods on the
|
||||
call stack. If an exception is thrown inside this call, and it is uncaught, the
|
||||
value of `$password` may be leaked out to an attacker through the stack trace.
|
||||
We recommend configuring PHP to never output stack traces (either displaying
|
||||
them to the user or saving them to log files).

|
||||
2. `$outputFilename` is the path to save the decrypted plaintext file.
|
||||
3. `$password` is the password used for decryption.
|
||||
|
||||
**Behavior:**
|
||||
|
||||
Decrypts the contents of the input file, writing the result to the output file.
|
||||
If the output file already exists, it is overwritten.
|
||||
|
||||
**Return value:**
|

encrypt multiple ciphertexts under the same password, see the
|
||||
`KeyProtectedByPassword` class.
|
||||
|
||||
The input ciphertext is processed in two passes. The first pass verifies the
|
||||
integrity and the second pass performs the actual decryption of the file and
|
||||
writing to the output file. This is done in a streaming manner so that only
|
||||
a small part of the file is ever loaded into memory at a time.
|
||||
|
||||
**Cautions:**
|
||||
|
||||
PHP stack traces display (portions of) the arguments passed to methods on the
|
||||
call stack. If an exception is thrown inside this call, and it is uncaught, the
|
||||
value of `$password` may be leaked out to an attacker through the stack trace.
|
||||
We recommend configuring PHP to never output stack traces (either displaying
|
||||
them to the user or saving them to log files).
|
||||
|
||||
Be aware that when `Defuse\Crypto\WrongKeyOrModifiedCiphertextException` is
|
||||
thrown, some partial plaintext data may have been written to the output. Any
|
||||
plaintext data that is output is guaranteed to be a prefix of the original
|
||||
plaintext (i.e. at worst it was truncated). This can only happen if an attacker
|
||||
modifies the input between the first pass (integrity check) and the second pass
|
||||
(decryption) over the file.
|
||||
|
||||
It is impossible in principle to distinguish between the case where you attempt
|
||||
to decrypt with the wrong password and the case where you attempt to decrypt
|
||||
a modified (corrupted) ciphertext. It is up to the caller how to best deal with
|
||||
this ambiguity, as it depends on the application this library is being used in.
|
||||
If in doubt, consult with a professional cryptographer.

Class: Defuse\Crypto\Key
|
||||
=========================
|
||||
|
||||
The `Key` class represents a secret key used for encrypting and decrypting. Once
|
||||
you have a `Key` instance, you can use it with the `Crypto` class to encrypt and
|
||||
decrypt strings and with the `File` class to encrypt and decrypt files.
|
||||
|
||||
Instance Methods
|
||||
-----------------
|
||||
|
||||
### saveToAsciiSafeString()
|
||||
|
||||
**Description:**
|
||||
|
||||
Saves the encryption key to a string of printable ASCII characters, which can be
|
||||
loaded again into a `Key` instance using `Key::loadFromAsciiSafeString()`.
|
||||
|
||||
**Parameters:**
|
||||
|
||||
This method does not take any parameters.
|
||||
|
||||
**Return value:**
|
||||
|
||||
Returns a string of printable ASCII characters representing this `Key` instance,
|
||||
which can be loaded back into an instance of `Key` using
|
||||
`Key::loadFromAsciiSafeString()`.
|
||||
|
||||
**Exceptions:**
|
||||
|
||||
- `Defuse\Crypto\Exception\EnvironmentIsBrokenException` is thrown either when
|
||||
the platform the code is running on cannot safely perform encryption for some
|
||||
reason (e.g. it lacks a secure random number generator), or the runtime tests
|
||||
detected a bug in this library.
|
||||
|
||||
**Side-effects and performance:**
|
||||
|
||||
None.
|
||||
|
||||
**Cautions:**
|
||||
|
||||
This method currently returns a hexadecimal string. You should not rely on this
|
||||
behavior. For example, it may be improved in the future to return a base64
|
||||
string.

### Key::createNewRandomKey()
|
||||
|
||||
**Description:**
|
||||
|
||||
Generates a new random key and returns an instance of `Key`.
|
||||
|
||||
**Parameters:**
|
||||
|
||||
This method does not take any parameters.
|
||||
|
||||
**Return value:**
|
||||
|
||||
Returns an instance of `Key` containing a randomly-generated encryption key.
|
||||
|
||||
**Exceptions:**
|
||||
|
||||
- `Defuse\Crypto\Exception\EnvironmentIsBrokenException` is thrown either when
|
||||
the platform the code is running on cannot safely perform encryption for some
|
||||
reason (e.g. it lacks a secure random number generator), or the runtime tests
|
||||
detected a bug in this library.
|
||||
|
||||
**Side-effects and performance:**
|
||||
|
||||
None.
|
||||
|
||||
**Cautions:**
|
||||
|
||||
None.
|
||||
|
||||
### Key::loadFromAsciiSafeString($saved\_key\_string, $do\_not\_trim = false)
|
||||
|
||||
**Description:**
|
||||
|
||||
Loads an instance of `Key` that was saved to a string by
|
||||
`saveToAsciiSafeString()`.
|
||||
|
||||
By default, this function will call `Encoding::trimTrailingWhitespace()`
|
||||
to remove trailing CR, LF, NUL, TAB, and SPACE characters, which are commonly
|
||||
appended to files when working with text editors.
|
||||
|
||||
**Parameters:**
|
||||
|
||||
1. `$saved_key_string` is the string returned from `saveToAsciiSafeString()`
|
||||
when the original `Key` instance was saved.
|
||||
2. `$do_not_trim` should be set to `TRUE` if you do not wish for the library
|
||||
to automatically strip trailing whitespace from the string.
|
||||
|
||||
**Return value:**
|
||||
|
||||
Returns an instance of `Key` representing the same encryption key as the one
|
||||
that was represented by the `Key` instance that got saved into
|
||||
`$saved_key_string` by a call to `saveToAsciiSafeString()`.
|
||||
|
||||
**Exceptions:**
|
||||
|
||||
- `Defuse\Crypto\Exception\EnvironmentIsBrokenException` is thrown either when
|
||||
the platform the code is running on cannot safely perform encryption for some
|
||||
reason (e.g. it lacks a secure random number generator), or the runtime tests
|
||||
detected a bug in this library.
|
||||
|
||||
- `Defuse\Crypto\Exception\BadFormatException` is thrown whenever
|
||||
`$saved_key_string` does not represent a valid `Key` instance.
|
||||
|
||||
**Side-effects and performance:**
|
||||
|
||||
None.
|
||||
|
||||
**Cautions:**
|
||||
|
||||
None.

Class: Defuse\Crypto\KeyProtectedByPassword
|
||||
============================================
|
||||
|
||||
The `KeyProtectedByPassword` class represents a key that is "locked" with
|
||||
a password. In order to obtain an instance of `Key` that you can use for
|
||||
encrypting and decrypting, a `KeyProtectedByPassword` must first be "unlocked"
|
||||
by providing the correct password.
|
||||
|
||||
`KeyProtectedByPassword` provides an alternative to using the
|
||||
`encryptWithPassword()`, `decryptWithPassword()`, `encryptFileWithPassword()`,
|
||||
and `decryptFileWithPassword()` methods with several advantages:
|
||||
|
||||
- The slow and computationally-expensive key stretching is run only once when
|
||||
you unlock a `KeyProtectedByPassword` to obtain the `Key`.
|
||||
- You do not have to keep the original password in memory to encrypt and decrypt
|
||||
things. After you've obtained the `Key` from a `KeyProtectedByPassword`, the
|
||||
password is no longer necessary.
|
||||
|
||||
Instance Methods
|
||||
-----------------
|
||||
|
||||
### saveToAsciiSafeString()
|
||||
|
||||
**Description:**
|
||||
|
||||
Saves the protected key to a string of printable ASCII characters, which can be
|
||||
loaded again into a `KeyProtectedByPassword` instance using
|
||||
`KeyProtectedByPassword::loadFromAsciiSafeString()`.
|
||||
|
||||
**Parameters:**
|
||||
|
||||
This method does not take any parameters.
|
||||
|
||||
**Return value:**
|
||||
|
||||
Returns a string of printable ASCII characters representing this
|
||||
`KeyProtectedByPassword` instance, which can be loaded back into an instance of
|
||||
`KeyProtectedByPassword` using
|
||||
`KeyProtectedByPassword::loadFromAsciiSafeString()`.
|
||||
|
||||
**Exceptions:**
|
||||
|
||||
- `Defuse\Crypto\Exception\EnvironmentIsBrokenException` is thrown either when
|
||||
the platform the code is running on cannot safely perform encryption for some
|
||||
reason (e.g. it lacks a secure random number generator), or the runtime tests
|
||||
detected a bug in this library.
|
||||
|
||||
**Side-effects and performance:**
|
||||
|
||||
None.
|
||||
|
||||
**Cautions:**
|
||||
|
||||
This method currently returns a hexadecimal string. You should not rely on this
|
||||
behavior. For example, it may be improved in the future to return a base64
|

|
||||
|
||||
### unlockKey($password)
|
||||
|
||||
**Description:**
|
||||
|
||||
Unlocks the password-protected key, obtaining a `Key` which can be used for
|
||||
encryption and decryption.
|
||||
|
||||
**Parameters:**
|
||||
|
||||
1. `$password` is the password required to unlock this `KeyProtectedByPassword`
|
||||
to obtain the `Key`.
|
||||
|
||||
**Return value:**
|
||||
|
||||
If `$password` is the correct password, then this method returns an instance of
|
||||
the `Key` class.
|
||||
|
||||
**Exceptions:**
|
||||
|
||||
- `Defuse\Crypto\Exception\EnvironmentIsBrokenException` is thrown either when
|
||||
the platform the code is running on cannot safely perform encryption for some
|
||||
reason (e.g. it lacks a secure random number generator), or the runtime tests
|
||||
detected a bug in this library.
|
||||
|
||||
- `Defuse\Crypto\Exception\WrongKeyOrModifiedCiphertextException` is thrown if
|
||||
either the given `$password` is not the correct password for this
|
||||
`KeyProtectedByPassword` or the ciphertext stored internally by this object
|
||||
has been modified, i.e. it was accidentally corrupted or intentionally
|
||||
corrupted by an attacker. There is no way for the caller to distinguish
|
||||
between these two cases.
|
||||
|
||||
**Side-effects and performance:**
|
||||
|
||||
This method runs a small and very fast set of self-tests if it is the very first
|
||||
time this method or one of the `Crypto` methods has been called. The performance
|
||||
overhead is negligible and can be safely ignored in all applications.
|
||||
|
||||
**Cautions:**
|
||||
|
||||
PHP stack traces display (portions of) the arguments passed to methods on the
|
||||
call stack. If an exception is thrown inside this call, and it is uncaught, the
|
||||
value of `$password` may be leaked out to an attacker through the stack trace.
|
||||
We recommend configuring PHP to never output stack traces (either displaying
|
||||
them to the user or saving them to log files).
|
||||
|
||||
It is impossible in principle to distinguish between the case where you attempt
|
||||
to unlock with the wrong password and the case where you attempt to unlock
|
||||
a modified (corrupted) `KeyProtectedByPassword. It is up to the caller how to
|
||||
best deal with this ambiguity, as it depends on the application this library is
|
||||
being used in. If in doubt, consult with a professional cryptographer.

|

|
||||
### KeyProtectedByPassword::createRandomPasswordProtectedKey($password)
|
||||
|
||||
**Description:**
|
||||
|
||||
Generates a new random key that's protected by the string `$password` and
|
||||
returns an instance of `KeyProtectedByPassword`.
|
||||
|
||||
**Parameters:**
|
||||
|
||||
1. `$password` is the password used to protect the random key.
|
||||
|
||||
**Return value:**
|
||||
|
||||
Returns an instance of `KeyProtectedByPassword` containing a randomly-generated
|
||||
encryption key that's protected by the password `$password`.
|
||||
|
||||
**Exceptions:**
|
||||
|
||||
- `Defuse\Crypto\Exception\EnvironmentIsBrokenException` is thrown either when
|
||||
the platform the code is running on cannot safely perform encryption for some
|
||||
reason (e.g. it lacks a secure random number generator), or the runtime tests
|
||||
detected a bug in this library.
|

**Side-effects and performance:**
|

|

This method runs a small and very fast set of self-tests if it is the very first
|

time this method or one of the `Crypto` methods has been called. The performance
|

overhead is negligible and can be safely ignored in all applications.
|

**Cautions:**
|
||||
|

value of `$password` may be leaked out to an attacker through the stack trace.
|
||||
We recommend configuring PHP to never output stack traces (either displaying
|
||||
them to the user or saving them to log files).
|
||||
|
||||
Be aware that if you protecting multiple keys with the same password, an
|
||||
attacker with write access to your system will be able to swap the protected
|
||||
keys around so that the wrong key gets used next time it is unlocked. This could
|
||||
lead to data being encrypted with the wrong key, perhaps one that the attacker
|
||||
knows.

|
||||
### KeyProtectedByPassword::loadFromAsciiSafeString($saved\_key\_string)
|
||||
|
||||
**Description:**
|
||||
|
||||
Loads an instance of `KeyProtectedByPassword` that was saved to a string by
|
||||
`saveToAsciiSafeString()`.
|
||||
|
||||
**Parameters:**
|
||||

||||
1. `$saved_key_string` is the string returned from `saveToAsciiSafeString()`
|
||||
when the original `KeyProtectedByPassword` instance was saved.
|
||||
|
||||
**Return value:**
|
||||
|
||||

|
||||
password-protected key as the one that was represented by the
|
||||
`KeyProtectedByPassword` instance that got saved into `$saved_key_string` by
|
||||
a call to `saveToAsciiSafeString()`.
|
||||
|
||||
**Exceptions:**
|
||||
|
||||
- `Defuse\Crypto\Exception\EnvironmentIsBrokenException` is thrown either when
|
||||
the platform the code is running on cannot safely perform encryption for some
|
||||
reason (e.g. it lacks a secure random number generator), or the runtime tests

* The checksum introduces a potential security weakness. For example,
|

* suppose we apply a checksum to a key, and that an adversary has an
|
||||
* exploit against the process containing the key, such that they can
|
||||
* overwrite an arbitrary byte of memory and then cause the checksum to
|
||||
* be verified and learn the result.
|
||||
*
|
||||
* In this scenario, the adversary can extract the key one byte at
|
||||
* a time by overwriting it with their guess of its value and then
|
||||
* asking if the checksum matches. If it does, their guess was right.
|
||||
* This kind of attack may be more easy to implement and more reliable
|
||||
* than a remote code execution attack.
|
||||
*
|
||||
* This attack also applies to authenticated encryption as a whole, in
|
||||
* the situation where the adversary can overwrite a byte of the key
|
||||
* and then cause a valid ciphertext to be decrypted, and then
|
||||
* determine whether the MAC check passed or failed.
|
||||
*
|
||||
* By using the full SHA256 hash instead of truncating it, I'm ensuring
|
||||
* that both ways of going about the attack are equivalently difficult.
|
||||
* A shorter checksum of say 32 bits might be more useful to the
|
||||
* adversary as an oracle in case their writes are coarser grained.
|
||||
*
|

* Because the scenario assumes a serious vulnerability, we don't try
