Subkey usage explanation:

  • ed25519/ABDA5B82F36D3DB2 2019-10-19 [S]
    • Main signing key. Located in a smart card (Yubikey 5 NFC).
  • cv25519/1B318A5615C632D0 2019-10-19 [E]
    • Main encryption key. Located in a smart card (Yubikey 5 NFC).
  • rsa2048/943D73C9AD8AFB50 2019-10-19 [S] [expires: 2021-03-01]
    • (Deprecated) On-card signing key. Located in a smart card (Yubikey 4, which doesn’t support Curve25519). I’m not using it any more.

My old key, 42F6 3E9D 68B9 884B 414D 4185 1029 4E7C 4008 E282, has been revoked. I have switched my PGP key to a newly generated ed25519 / cv25519 one, and I’m applying some best practices I learned after I’ve created my last PGP key. If you have signed on my old key, you can trust my new key since I’ve signed it with my old key in prior to the revocation. (Unfortunately this process is still not a best practice!)
