Combined PGP Keys Into One
After finding out today that pgp keys can have multiple email addresses, I revoked all but public key and combined all emails into one key.
Edit a key in the terminal:
> gpg --edit-key KEY_ID Command> adduid
Add name and email address. Then remember to set a primary uid:
Command> uid NUMBER_IN_PARENTHS_TO_SELECT Command> primary Command> save
Should be all good. Remember to revoke the old keys and re-export the public key.
You can share your public key with others easier by uploading it to a key server like MIT
