we ought to have a AI bot that plants thes posts at the bottom of the appropriate thread since they come around every few weeks, just make your own file extension up to idebtify the file to your program and so it knows that .sav is a savegame and .map is a levelmap etc, you can use bytes or strings or whatever you like, just read em back in the same order as what you wrote em, as for encryption, heres a simple example app that encrypts a bitmap into a .xxx file (an own named filetype), you can`t read the bitmap unless you have the key, for more security you could encrypt it several times with different keys, that way the complexity increases by the power of whatever number range you use for each pass....
