PGP signed messages about pat HOT 3 OPEN

To clarify this a bit. What I'm suggesting here is to support what's known as clear-signing.

The common way to PGP sign emails is using PGP/Mime, but this does not seem to be compatible with the winlink message format.

More on the difference between clear-signing vs. PGP/Mime here:

if pat would act as a regular email transport (#96), this complicated piece of software wouldn't need to be implemented directly in pat.

i've work with PGP for over a decade and wrote various software talking with the main implementation (GnuPG) and I can tell you: it's hard. there are all sorts of corner cases and issues (the message format is one, for sure). GPG is especially hard to interoperate with. i would strongly discourage you from implementing this yourself and instead delegate it to another email client. for example, there's an in-browser plugin called mailvelope which integrates directly in the webmail and could integrate in pat's web interface quite nicely. if pat does allow other email clients to talk to it (#96 again), this would also be neatly resolved.

Thanks for the insight @anarcat, we must definitely consider this when the time comes to look at this again.

mailvelope sounds like a great alternative for the web ui users. We should test it, and possibly figure out what changes are needed in order to support it! One important thing to ensure is that is will function without an internet connection.
