AES128 / AES256 CBC with PKCS7Padding in PHP

gistfile1.php

function aes256EcbPkcs7PaddingEncrypt($key, $data) {
    $padding = 16 - (strlen($data) % 16);
    $data .= str_repeat(chr($padding), $padding);
    return mcrypt_encrypt(MCRYPT_RIJNDAEL_128, hash('SHA256', $key, true), $data, MCRYPT_MODE_ECB);
}

function aes256EcbPkcs7PaddingDecrypt($key, $data) {
    $data = mcrypt_decrypt(MCRYPT_RIJNDAEL_128, hash('SHA256', $key, true), $data, MCRYPT_MODE_ECB);
    $padding = ord($data[strlen($data) - 1]); 
    return substr($data, 0, -$padding); 
}

Nice ,,, keep it up

I'm not sure if there's another page explaining the context of this gist. For anyone who got here without context (e.g. from Google) - like I did - please note that creating an IV using str_repeat("\0", 16) makes this code absolutely not production-ready! See Block cipher mode of operation at Wikipedia for more details. In short, "In CBC mode, the IV must... be unpredictable at encryption time."

@bojanmartin Yes, you must create it with http://php.net/manual/en/function.mcrypt-create-iv.php

Superb!

Nice ty !

it's deprecated on php 7+
