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.

After you have copied it, click on the clipboard icon at the top taskbar and select “Decrypt/Verify Clipboard”.

A new window should pop up which contains “Good signature from ” at the bottom, if the signature was correct.
