Hi Nathan,

Are you sure you're just not misunderstanding how to reverse the
encryption with gnupg?

(Encrypt the ascii file a symmetrically with out any compression.)

(Encrypt the ascii file a.asc symmetrically with out any compression.)

So you're encrypting twice above - but perhaps you where trying to
illustrate something and I missed it?

If you wanted to decrypt the PGP encrypted message/data in the file
a.asc you should use the command `gpg -d a.asc`.

Because IDEA is patented.

Symmetric Encryption works fine for me.  I'm running gnupg 1.0.4 (patched)
on Mandrake 7.2 w/2.4.2, w/gcc 2.9.35 - although my mandrake install has
been rather heavily modified.
