SSHA and friends

[rudi.hatheyer at alphanova.at (Rudolf Hatheyer)]

Hi Gerrad,

I use php in my self written usermanagement webapp.

Here a code snippet (part of a utility class) which works for me:

protected function generateSSHAHash($plaintext) {
        mt_srand((double)microtime()*1000000);
              
        $salt = $this->myhash_keygen_s2k(
                                    $plaintext,
                                    substr(pack('h*', md5(mt_rand())), 
0, 8),
                                    4 );
        $hash = "{SSHA}".base64_encode(hash('sha1', $plaintext.$salt, 
TRUE).$salt);

        return $hash;    
 }

protected function myhash_keygen_s2k($pass, $salt, $bytes ){
      return substr(pack("h*", sha1($salt . $pass)), 0, $bytes);
}

Cheers, Rudolf
