Build Status

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. 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

composer.json:

{
    "require": {
        "whitehat101/apr1-md5": "~1.0"
    }
}

Use

use WhiteHat101\Crypt\APR1_MD5;

// Check plaintext password against an APR1-MD5 hash
echo APR1_MD5::check('plaintext', '$apr1$PVWlTz/5$SNkIVyogockgH65nMLn.W1');

// Hash a password with a known salt
echo APR1_MD5::hash('PASSWORD', '__SALT__');

// Hash a password with a secure random salt
echo APR1_MD5::hash('PASSWORD');

// Generate a secure random salt
echo APR1_MD5::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.
