Hi,

I have a few issues with the following php functions (part of a bigger class).

    //encode
    public function acc_pw_enc($text, $key) {
    $text_num = str_split($text, 8);
    $text_num = 8 - strlen($text_num[count($text_num)-1]);

    for ($i=0; $i < $text_num; $i++) {
        $text = $text . chr($text_num);
    }

    $cipher = mcrypt_module_open(MCRYPT_TRIPLEDES, '', 'cbc', '');
    mcrypt_generic_init($cipher, $key, 'fYfhHeDm');
    $decrypted = mcrypt_generic($cipher, $text);
    mcrypt_generic_deinit($cipher);
    return base64_encode($decrypted);
}

    //decode
public function acc_pw_dec($encrypted_text, $key) {
    $cipher = mcrypt_module_open(MCRYPT_TRIPLEDES, '', 'cbc', '');
    mcrypt_generic_init($cipher, $key, 'fYfhHeDm');
    $decrypted = mdecrypt_generic($cipher, base64_decode($encrypted_text));
    mcrypt_generic_deinit($cipher);
    $last_char = substr($decrypted, -1);

    for($i=0; $i < 8-1; $i++) {
        if(chr($i) == $last_char) {      
            $decrypted = substr($decrypted, 0, strlen($decrypted)-$i);
            break;
        }
    }
    return rtrim($decrypted); //str_replace("?", "", $decrypted);
}

So for exampe if i encrypt the string 'liloMIA01' with the salt/key 'yBevuZoMy' i will get '7A30ZkEjYbDcAXLgGE/6nQ=='.

I get liloMIA01 as the decrypted value, i tried using rtrim but it didn't work.
