Built-in PGP encryption.

Disclaimer: The Bazaar team reminds you that the best practice for using PGP encryption is to encrypt text locally and then transmit the encrypted text over the network.

If the buyer wishes, they can automatically encrypt text messages to the seller using PGP. The system will use the seller's public key and display the encrypted message to the seller.
If the buyer has added a PGP key, the seller will also be able to send them encrypted messages.

If you receive an encrypted message, you can only decrypt it locally using your private key.
