Make shared memory work for you, not against you

Last time I showed you how to exchange and verify public PGP keys with an individual. After you’ve verified a user’s key (KeyID, bits, type, fingerprint, and user’s actual identity) you should sign their key.

Verification is part of any security system. SSH, FTP, POP, and IMAP servers ask for your password before it lets you log into the machine, get your files, or snag your email. NTP can be configured to require keys before it’ll let you mess with it’s clock. CIFS requires a password or kerberos tickets before granting you access to shares.

GnuPG and other PGP implementations allow you to encrypt (scramble the data so only intended recipients can read it) and/or sign (provide proof that the data has been unaltered in transit). As you should remember, PGP keys are made up of two parts, a public key and a private key. The public key can (and in most cases should) be available to anyone – there’s no harm in allowing it out to the entire world. The private key should be kept somewhere secure, protected with a strong passphrase.
