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.

  • My new key: E6C7 4782 A1FB EE74 1D09 885F D274 286F 672C 800A.

Fetch my key from keys.openpgp.org or SKS keyservers (not recommended).

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!)
