Other people's keys
To encrypt for someone, you need their public key. It can arrive:
- attached to an email or through the Autocrypt header: it comes in as “not yet accepted”;
- from a file or the clipboard;
- from the internet, only when you ask: EpistulaMail asks the person’s domain and
keys.openpgp.org.
Acceptance follows Thunderbird’s style: not yet, accepted, verified or rejected.
