The proper newsgroup for this question is sci.crypt.

Data security is a complex and difficult problem, and you are likely
to fail in the worst possible way: implementing something that is
weak but that you believe to be strong.  Some advice: (1) Use
off-the-shelf products like PGP or GPG; don't write your own.
(2) Read Bruce Schneier's Applied Cryptography to get a feeling
for the dimensions of the problem. (3) Start by composing a
clear statement of what you need, avoiding vague terms like
"security".  If you don't know where you're going, you can't
tell whether you've arrived.
