it is probably a good idea to have the key expire. I imagine there is a lot of keys out there where people did generate a key and then forgot what their passphrase was.

Also when you generate the key make a revocation cert. If you lose the key or it gets compromised you can then revoke the key.

good point, theru

Yes, I had never thought about that use of expiry dates. Thanks.

I also never thought to make the revocation cert at the time of key generation. That's a good idea.

Thanks for listening and thanks for the tips!

I'm pretty sure that encryption is done only with the recipient's public key. You want to use your own private key to save a copy in your 'sent' folder, though. Evolution wants the sender's public key but that is AFAIK just a quirk that is specific to Evolution. Great show!! I would like more people to get into gpg signing and encrypting messages.
