Thank you for making it - it's an awesome tool !
If I could make a suggestion, it would be to look at how the person at the other end gets the keys to decrypt a message. Currently, it's fine between two people who are already signed up and familiar with Hive.
Perhaps what is needed is a "standard text" that can be pasted into a (separate) email or (in an ideal case) printed out and passed over by hand beforehand explaining in idiot-proof layman's terms how to sign up and get set up to decrypt. But I can also see the risk that doing that means a bad actor might intercept the instructions as it would have to be sent unencrypted. Is there any kind of receiver verification, so that the encrypted email includes data for the system to recognise behind the scenes whether the user name and keys match those of the expected recipient ?
