Hi Frank,

> I guess what I'd like is a tutorial/example that:
The wiki and FAQ have plenty of samples. See
http://www.cryptopp.com/wiki/ and
http://www.cryptopp.com/fom-serve/cache/1.html. As far as the FAQ, see
the entry, "How do I use a block cipher in Crypto++ 5.x?".

The cipher is of little consequence - Crypto++ code is written in such
a way that the objects expose a consistent interface. So there is
nothing special to using 3DES.
