Only allow OpenPGP keys that match the provided email in WhisperBack
- Only allow GPG keys that match the provided email, because Schleuder doesn’t allow to write encrypted emails to an address with a different key.
- Force user to provide armored public GPG key instead of just key ID (the keys are sometimes hard or impossible to fetch on the keyservers, and sometimes two keys share the same ID).
Those improvements would greatly simplify Frontdesk work.
