How PGP Works: Key Management

Adding a key to your keyring: pgp -ka keyfile

• Adds the key in keyfile to your keyring.

• Posits a binding between the key and userID
• Create a hash of the key and userID, and encrypt in signer's private key
• Becomes a part of the public key certificate

• take a key from your keyring and allow you to send it to others.
• It will create a key block:

  -----BEGIN PGP PUBLIC KEY BLOCK-----
  Version: 2.6.2

  -----END PGP PUBLIC KEY BLOCK-----

• It is a hash of the Public key, printed in a means to repeat over the phone:
