encrypting save game data

anyone know of a simple way to encrypt decrypt text files so the average person cant edit the save game files?

or is it not worth the bother?

Check out Xor command in the help files...

I was about to write an example and needed to check that Xor was available - turns out there is already one in there for lightweight encryption :-)

I wrote something to do this recently. It's in the code archives :
