How in the F*** do you understand that nonsense
Base64 encoding where the base message is 3*n+1 characters ends in ==, while Base64 encoding where the base message is 3*n+2 characters ends in =.
After using a base64 decoder, I got a string of 1s and 0s, which a binary translator gave me the text equivalent.
P.S. I didn't solve csmith's code, but the other code was a Freedom Force one, not sure if it's taken or not yet.
