how to make phalcon 128 character encryption?

Hi, I'm still new to Phalcon and I was wondering on how to make a 128 character encryption.

Many thanks in advance.

I don't think Phalcon has any built-in encryption functionality. You might as well just use the native PHP functions.

If you're refering to 128-bit encryption, you can use native functions:

$iv_size = mcrypt_get_iv_size(MCRYPT_RIJNDAEL_128, MCRYPT_MODE_CBC);
$iv = mcrypt_create_iv($iv_size, MCRYPT_RAND);

# creates a cipher text compatible with AES (Rijndael block size = 128)
# to keep the text confidential 
# only suitable for encoded input that never ends with value 00h
# (because of default zero padding)
$ciphertext = mcrypt_encrypt(MCRYPT_RIJNDAEL_128, $key, $plaintext, MCRYPT_MODE_CBC, $iv);

# prepend the IV for it to be available for decryption
$ciphertext = $iv . $ciphertext;

# encode the resulting cipher text so it can be represented by a string
echo base64_encode($ciphertext);

With Phalcon\Crypt:

<?php

//Create an instance
$crypt = new Phalcon\Crypt();

$key = 'le password';
$text = 'This is a secret text';

$crypt->setMode(MCRYPT_MODE_CBC);
$crypt->setCipher(MCRYPT_RIJNDAEL_128);
$encrypted = $crypt->encrypt($text, $key);

thanks a lot mr. @Phalcon.
