Algoritmo Rijndael de 128 bits en php

[walterdevel]

Con ecb:

Código PHP:

function decrypt($code, $key) {
 
  //$code = hex2bin($code);
  $td = mcrypt_module_open("rijndael-128", "", "ecb", "fedcba9876543210");
 
  mcrypt_generic_init($td, $key, "fedcba9876543210");
  $decrypted = mdecrypt_generic($td, $code);
 
  mcrypt_generic_deinit($td);
  mcrypt_module_close($td);
 
  return $decrypted;
}
 
function encrypt($str, $key) {
  $td = mcrypt_module_open("rijndael-128", "", "ecb", "fedcba9876543210");
 
  mcrypt_generic_init($td, $key, "fedcba9876543210");
  $encrypted = mcrypt_generic($td, $str);
 
  mcrypt_generic_deinit($td);
  mcrypt_module_close($td);
 
  return $encrypted;
}
 

Lo acabo de probar y funciona. Saludos!
