Are you sure you just don't want someone to write the program for you?

Wait...oh never mind.

Piece of code from an app i wrote a while back to pack and unpack patch files.

XOREn and StringCipher is part of a custom library i made for client data files.

This is the zlib library I used.

P.S.
The code he posted is not the correct string cipher. Mine is a custom written class for resource file names. Look up a project i released a while back called DataBurner the class is called something different but its still the same methods.

And it will also have the XOR method although it may or may not be in its own class in that version.
