Openwall Phpass, namespaced with composer

Openwall Phpass, modernized

This is Openwall's Phpass, based on the 0.3 release, but modernized slightly:

• Namespaced
• Composer support (Autoloading)
• PHP 5 style
• Unit Tested

The changes are minimal and mostly stylistic. The source code is in the public domain. We claim no ownership, but needed it for one of our projects, and wanted to make it available to other people as well.

• 1.1.0 - Modified to add random_bytes hook function.
• 1.0.0 - Modified to use hash_equals to be resistant to timing attacks. This requires php >= 5.6.0.
• 0.3.x - Very close to the original version. Requires php >= 5.3.3.

Customizing the Source of Randomness

In version 1.1.0, the get_random_bytes function checks for the presence of a random_bytes function. If a random_bytes function is callable, then random_bytes will be used as the source for random bytes output. Otherwise, the original get_random_bytes code will be used.

Installation

Add this requirement to your composer.json file and run composer.phar install:

{
    "require": {
        "hautelook/phpass": "1.0.0"
    }
}

Usage

The following example shows how to hash a password (to then store the hash in the database), and how to check whether a provided password is correct (hashes to the same value):

<?php

namespace Your\Namespace;

use Hautelook\Phpass\PasswordHash;

require_once(__DIR__ . "/vendor/autoload.php");

$passwordHasher = new PasswordHash(8,false);

$password = $passwordHasher->HashPassword('secret');
var_dump($password);

$passwordMatch = $passwordHasher->CheckPassword('secret', "$2a$08$0RK6Yw6j9kSIXrrEOc3dwuDPQuT78HgR0S3/ghOFDEpOGpOkARoSu");
var_dump($passwordMatch);
