Q. How do I use PGP?

A. PGP is in /usr/local/bin, make sure it is in your path with "which pgp".

To generate a key pair:

pgp -kg

Accept the defaults, and choose the level of security you want. Use your email address in the form user@cs.sunysb.edu for your user ID.

To extract your own public key into a file:

pgp -kx <your_pgp_userid> <keyfilename>

To add someone's public key to your keyring:

pgp -ka <keyfilename>

To encrypt a file:

pgp -seat <filename> <pgp_userid_of_recipient>

This will produce a file called filename.asc suitable for inclusion in an email message.

To decrypt a file:

pgp <filename>

To view the keys on your keyring:

pgp -kv

For more information on these and other options please see the man page or the PGP Documentation.
