if you use blowfish and somehow when you compare strings before and after it was (usually when
it's shorter than 8 or 16 bytes) you might notice the difference, it comes out that this
function does not remove padding, as a result you get a bunch of nulls at the end.
use
$decrypted = rtrim($decrypted,"\0");
to fix it
