Verifying a message with PGP #

Verifying messages is commonly used to check the authenticity of market links. Markets publish signed messages containing links to their market. If you have the market’s public key you can use it to verify that the message was created by the market and that the links are legitimate.

Markets, vendors and moderators will sometimes sign announcements or warnings. You can also use this to verify those.
