Bug description: possible bad padding
I noticed something quite strange when using the mcrypt library to encrypt
data.
say i would encrypt $data in mode ECB:
$l = mcrypt_encrypt(MCRYPT_BLOWFISH, $key, $data, MCRYPT_MODE_ECB, $iv);
then decrypt it:
$l = mcrypt_decrypt(MCRYPT_BLOWFISH, $key, $data, MCRYPT_MODE_ECB, $iv);
It seems like the padding prevents me from using the variable correctly in
some conditions.
As explained in the documentation, the padding is made of '\0' and in the
following example:
<? exec("echo.sh $l foobar", $value, $return);
exec would actually stop at $l because of the '\0' and not pass the
'foobar' arg.
I don't know if this is a known bug or a "supposed" behaviour, but it is
surely annoying :)
