pgp uses a pair of 'keys', 'public' and 'private' . if someone want's to encrypt a message to you they use your public key, that way only you can decrypt it with your private key+passphrase. you could give this public key directly to them or publish it on a pgp keyserver (pgp.mit.edu), that way anyone can look up your public key if they know your email.

your best bet is to read gpg man page, due to the enormous amount of flags and options available. to encrypt a file with tom's public key it would look like

gpg -e -r tomskeyid <filetoencrypt>
