Send encrypted email in thunderbird

I am trying to send an encrypted email in thunderbird.

gpg --search-keys nous@artixlinux.org
gpg: data source: https://185.125.188.26:443

Code: [Select]

gpg --export -a "<nous@artixlinux.org>" > nous.key

I opened that in thunderbird but still error "No key available".

But I sent you a PM with instructions how to encrypt a text file in the command line...

Good thing those email harvesting bots seem to like my email...

It is NOT certain that the key belongs to the person named
in the user ID.  If you *really* know what you are doing,
you may answer the next question with yes.

Use this key anyway? (y/N) y

no idea how this works

Choosing 606520ACB886B428 does the same

why your master not Ed25519?

After adding also the key 3 I imported the file generated with this in thunderbird and now it shows encryption possible.

Code: [Select]

gpg --export -a "<nous@artixlinux.org>" > nous.key

Edit: When I try to send the email some error happens.

"Sending of the message failed".

Yes, I've verified in person this key has the correct fingerprint.

In Key Manager.

Not sure if I was suppose to verify something.
