I think that I have encryption all figured out and such, but still, look at my (simple) code that encrypts a single character by flipping bits (a char* can be run through this, as well as int's).
Another question: is there a simple way to split a short into 2 bytes and a long into 4 bytes for the latter?

unsigned long dwLong = 123456;unsigned char* pbyBuff = (unsigned char*)&dwLong Now pbyBuff[0] ... pbyBuff[3] contain the four bytes of dwLong.
