Mcrypt

[Anon]

Hi Everyone,
When I try to execute the code below, I don't get any errors, but the data is never decrypted. I have tried tons of different people's code, but to no avail. Any help would be appreciated. Here is my code:

$data= mcrypt_ecb(MCRYPT_TripleDES, $key, $data, ENCRYPT);
echo "data: $data";

$data= mcrypt_ecb(MCRYPT_TripleDES, $key, $data, DECRYPT);
echo "data: $data";

And here is the output:

Warning: attempt to use an empty IV, which is NOT recommend in ../../includes/scripts/admin_functions.inc on line 52
data is: áyp)l)©>¤IÔNþ&ñ¸«Ø¼{j<{’Â]Ƹ«Ø¼{j<{’Â]Ƹ«Ø¼{j<{’Â]Ƹ«Ø¼{j<{’Â]Ƹ«Ø¼{j<{’Â]Ƹ«Ø¼{j<{’Â]Æ—¶µßÛKš á×½ÄeDÜ

Even when I try to use an IV, it still doesn't ever decrypt, or sometimes it will give me an error about the key being too long.

Thanks very much in advance,
