Quote from: jojo on November 18, 2012, 01:18 amI have a mac and installed GPG. So does the vendor need to supply me with a key?Yes, the vendor needs to supply you with their PGP key, which you add to your PGP keyring. When you go to encrypt a message, you encrypt it to the vendor's key as well as your own. If you wish to communicate securely with your vendor, you also need to supply him/her with your PGP key. Head over to the PGP Club thread to get some practice using the software. Nightcrawler
