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)
|
||||
|
||||
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:

|

* SECURITY NOTE ON APPLYING CHECKSUMS TO SECRETS:
|
||||
*
|
||||
* 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
|
||||
* to prevent attacks of this style.
