Also,
If you're using the 'od -x' command to look at binary data, it's often
times byte reversed within 16 bit values on x86 architectures. This always
throws me on Linux systems. I beleive that there's an option to od that
tells it you want to deal with byte values rather than byte reversed 16 bit
words.

> My only problem is the incompatibilty between the executables I compiled
under Windows and Unix. As far as I can tell the order of the encrypted
bytes is reversed. For example in Windows the bytes would be 1234 5678
while in Unix they are 4321 8765. Eaach of the for bytes are represented by
unsigned longs

know why this is happening and how do I correct it.
