This solution was by @dataclickes on eusonlito/redsys-TPV#14 meaby it help you to fix that.

function encrypt_3DES($message, $key) {

     $l = ceil(strlen($message) / 8) * 8;
    return substr(openssl_encrypt($message . str_repeat("\0", $l - strlen($message)), 'des-ede3-cbc', $key, OPENSSL_RAW_DATA, "\0\0\0\0\0\0\0\0"), 0, $l);
}

I tested on my integration with Redsys and work fine. jesusangel/wc-sermepa@9e0a013
