Django's password hashing ported to PHP

hash_password.php

<?php
    private function set_password($raw_password) {
        /*
            Sets the password to a string of random sha1 salt
            and encrypted password.

            Separated by '$'
        */
        $salt = substr(sha1(genRandomString().genRandomString()), 0, 5);
        $hash = sha1($salt.$raw_password);
        $enc_password = $salt.'$'.$hash;
        $this->password = $enc_password;
    }

    public function check_password($raw_password, $enc_password) {
        /*
            Returns a boolean of whether the raw_password was correct.
        */
        $pieces = explode('$', $enc_password);
        $salt = $pieces[0];
        $hash = $pieces[1];

        if ($hash == sha1($salt.$raw_password))
            return true;
        else
            return false;
    }

function genRandomString($length = 5) {
    $retval = "";
    for ($i=0; $i < $length; $i++) { 
        $retval .= chr(rand(97,122));
    }
    return $retval;
}

this just saved me a ton of time. THANK YOU so much!

Thank you so much !

This doesn't work on Django 1.9+
