Hmm ... as I mentioned in my other message a few minutes ago, I seem to
need the _recipient's_ passphrase in order to decrypt my archived
copies, even with the latest CVS of Gnus.

Also, I think there's a gap somewhere in my understanding of all this.
How can it be that something encrypted twice, once with the recipient's
public key and once with yours, would only need your private key to be
decrypted?  Wouldn't there have to be two decryptions, one for each of
the previous encryptions?  Or in this case, is the encryption done with
some sort of mathematical combination of both public keys, such that
either corresponding private key can decrypt it?

That's not such a problem for me.  I just want to be able to _read_
these archived copies.
