How PGP Works

Major parts of PGP:

• Keys
  • Users create their own Public/Private keypairs
  • Users can have multiple keys
  • Users maintain a keyring of cached public keys
• Messages
  • Encrypt messages to people "using their Public Key"
  • Sign messages using your Private Key
  • Decrypt/Verify messages
• Key Management
  • Add/remove keys from the keyring
  • Sign a key
  • Extract public keys to send to others (exchange keys)
  • Fingerprint keys (to help verify keys)

• A way to exchange PGP Public Keys
• Email Interface: Send mail to pgp-public-keys@pgp.mit.edu
