CRYPTF - Scrambles a file in place on disk. Prompts for a key of up
to 32 bytes. Exit codes are generated to facilitate use in
batch files. The program always scrambles the file using
the specified key, which means that:
1. Processing a file with a key will scramble it.
2. Processing a scrambled file with the same key will
unscramble it.
3. Processing a scrambled file with a different key will
scramble it again. ( This may be repeated ad nauseum
and if you can remember to use the right keys in the
right order, the file can still be unscrambled! ).
To run: cryptf [d:][dir]filename.ext
**WARNING** Since this is an in-place update, termination of the
**WARNING** program during I/O is almost certain file death!
