I've occasionally thought about writing a very simple program that can
handle OpenPGP symmetric encrypted files (i.e. gpg --symmetric).  I
expect it wouldn't be that difficult to do, especially since the
crypto stuff can be trivially pulled in from gcrypt or openssl, or use
the crypto hardware on some platforms like yours.
