here is an example using this function with mode cfb: function decrypt_normal($key, $c_t) { // incoming: should be the $key that you encrypted // with and the $c_t (encrypted text) // returns plain text // decode it first :) $c_t = trim(chop(base64_decode($c_t))); /* generate an initialization vector */ $iv = substr(md5($key), 0,mcrypt_get_iv_size (MCRYPT_CAST_256,MCRYPT_MODE_CFB)); /* now we do our normal decrypting */ $p_t = mcrypt_decrypt (MCRYPT_CAST_256, $key, $c_t, "cfb", $iv); return trim(chop($p_t)); }
