Looking at the problem further, I am getting the idea that
PGP, or GPG (Asymetric encryption) would be better, because
then all of the software that has to *write* CC numbers, would
not have to access the 'secret' key.  You see we have to write
the number often, but almost always only have to access (read)
a masked number (4232********3435).

PGP sounds great, but it seems like a huge subject to cover
in a day or two.  Is there a nice module for python that would
let me do the most usual operations easily?  I just want to make
a key, hide it, and the use the public key to encrypt all future
and past credit card numbers.
