PHP difference between mcrypt and openssl?

Why have these two methods of using blowfish in ecb-mode different outputs?

<?php

echo bin2hex(mcrypt_encrypt("blowfish", "test", "test", "ecb"))."\n";
echo bin2hex(openssl_encrypt("test", "bf-ecb", "test", true))."\n";

?>
Solution

  • Because of different password-to-encryption-key derivation methods.
