Apache's APR1 MD5 Hashing Algorithm in PHP
==========================================

[](#apaches-apr1-md5-hashing-algorithm-in-php)

[![Build Status](https://camo.githubusercontent.com/0f342c2dbbb4af0e2632a898fba5603d8d2656ab5b0d9b24f0f3f5ce9c4005c3/68747470733a2f2f7472617669732d63692e6f72672f77686974656861743130312f617072312d6d64352e737667)](https://travis-ci.org/whitehat101/apr1-md5)

There is no way that the best way to generate Apache's apr1-md5 password hashes is from a [7-year-old comment on php.net](http://www.php.net/manual/en/function.crypt.php#73619). Only a n00b would trust a crypto algorithm from a non-security website's forum. Sadly, that is how the PHP community has accessed this algorithm, until now.

Here is a tested, referenced, documented, and packaged implementation of Apache's APR1 MD5 Hashing Algorithm in pure PHP.

Install
-------

[](#install)

composer.json:

```
{
    "require": {
        "zonuexe/apr1-md5": "~1.0"
    }
}
```

Use
---

[](#use)

```
use zonuexe\Apr1md5;

// Check plaintext password against an APR1-MD5 hash
echo Apr1md5::check('plaintext', '$apr1$PVWlTz/5$SNkIVyogockgH65nMLn.W1');

// Hash a password with a known salt
echo Apr1md5::hash('PASSWORD', '__SALT__');

// Hash a password with a secure random salt
echo Apr1md5::hash('PASSWORD');

// Generate a secure random salt
echo Apr1md5::salt();
```

The ideal `__SALT__` is an 8 character string. Valid salts are alphanumeric and `.` or `/`. Shorter salts are allowed. Longer salts are truncated after the 8th character.
