1For now, read the header comments inside each of these for documentation.
2The programs are simple enough that they don't really need a Makefile any more
3complex than the one given; ymmv. Data and xor may also be useful on DOS,
4which is why there are hooks for it in the code.

5 With no args, xors stdin against 0xFF to stdout. A single argument is a
6 file to read xor-bytes out of. Any zero in the xor-bytes array is treated

8 you're on your own.

10 The indirect file can be generated easily with data.c.
11
12 Written because there are so many lame schemes for "masking" plaintext
