  "textContent": "One PGP key pair can have multiple identities including email addresses.\n\nSee OpenPGP Key Management (Using the GNU Privacy Guard) --quick-add-uid user-id new-user-id\n\nNo idea if Proton allows to easily do that.\n\nrandomperson:\n\n> It would not ensure that myalias is actually myalias.\n\nIf you add it as a vaild user id it should. Again no idea how well proton supports that. Anyways the question was about encrypting, not signing.\n\nrandomperson:\n\n> It would reveal that myrealidentity is most likely behind myalias.\n\nCorrect, using the same key pair for two or more email addresses allows others to know they are owned by the same entity. Alternatively one could generate a unique key pair for every alias they want to receive encrypted messages on.",
