[casual_games] Encrypting text files

[Ricky Haggett]

Hey folks,

 

Our engine makes extensive use of xml and lua to mark up GUI, provide
scripting, level data, save game files etc.

 

This is all great, but one issue we have is that these text files can be
opened and edited, to hack the save game file and otherwise muck around with
the internal gubbins of the game.

 

What I’m after is a software layer that sits between the engine and the file
system, encrypting text files on write (for writing save data) and
decrypting on read. There’d also need to be an offline tool which encrypts
text files generated by hand (e.g. those containing scripting).

 

Can anyone recommend something suitable (in c / c++)?

 

Cheers,

 

Ricky Haggett
