Here are my functions to do a 128 bit aes encryption which is transmitted
to the dachser parcel tracking system via url. They expect a true aes
128 bit encryption an process the reqest by a java script. The decrypt
function is just a giveaway.
function aes_128_encrypt($text,$password) {
$size = mcrypt_get_iv_size(MCRYPT_RIJNDAEL_128, MCRYPT_MODE_CBC);
$iv = mcrypt_create_iv($size, MCRYPT_DEV_RANDOM);
// The following line was needed because I didn't get the same hex value as expected by
forwarding agency
// I think its their bug
// Try to remove the line. If it works, too - fine!
$text .= chr(3).chr(3).chr(3);
return bin2hex(mcrypt_encrypt(MCRYPT_RIJNDAEL_128, $password, $text, MCRYPT_MODE_ECB, $iv));
} // End of function
function aes_128_decrypt($encrypted_text,$password) {
$size = mcrypt_get_iv_size(MCRYPT_RIJNDAEL_128, MCRYPT_MODE_CBC);
$iv = mcrypt_create_iv($size, MCRYPT_DEV_RANDOM);
return mcrypt_decrypt(MCRYPT_RIJNDAEL_128, $password, pack("H*", $encrypted_text),
MCRYPT_MODE_ECB, $iv);
} // End of function
