I'm not planning to develop an entire encryption thing in "a few
lines of C", and, as a great believer in learning from Schneier,
have no intention of writing any encryption code at all for any
of this.

I'll be using proven off-the-shelf encryption code (probably
cryptlib) to do the heavy lifting.  My C code will simply be a
wrapper that sits in the existing pipeline to ensure that what
goes to tape is encrypted and in such a way that I will have a
decent chance of extracting it unencrypted should the need for
that arise.

Cheers, Greg
