In days gone by I used to use #Enigmail to #ecrypt #e-mail messages where possible (precious few of my correspondents use encryption, sadly). This used to be an addon for #Thunderbird but support for it was dropped some time ago as native support for #OpenPGP was incorporated into it. After a long hiatus, I decided to get back to seeing how to use the new interface, particularly with version 102 of Thunderbird. It looks pretty easy once you've configured the settings.
