Verify the domain

  1. Fetch the key from this domain via https://cyphertux.net/pgp.txt or WKD (https://cyphertux.net/.well-known/openpgpkey/hu/dj3498u4hyyarh35rkjfnghbjxug6b19). Same fingerprint either way.
  2. Compare the fingerprint to the value on this page.
  3. Confirm the UID matches contact@cyphertux.net and that discovery hits this domain, not a mirror you did not choose.

Write encrypted

  1. Import the public key (file or WKD locate).
  2. Encrypt to contact@cyphertux.net with that fingerprint.
  3. Send with any MUA that can deliver OpenPGP mail to that UID. Matrix is fine for chat; mail is for sealed messages.

Not an identity

  • An X handle, even @Cyphertux
  • A screenshot of a chat, key, or this page
  • “We know each other” without a key check
  • A random DM from a lookalike account
  • Any key that is not served from cyphertux.net
