@codewiz @thunderbird @mozilla well, I think it's not a regression but quality-of-life change necessistated by using Mozilla's NSS libraries instead of GnuPG.
Also GnuPG has a shitton of UX issues as it doesn't allows to be used like any other CLI tool can.
One can't simply do:
gpg --encrypt ./unencrxpted.file ./public.key
or
gpg --decrypt ./encrypted.file ./private.key
and that alome pisses me off!
Whereas it makes sense for #Thunderbird to maintain the keys and transparently do encryption.
