Using the GNU Privacy Guard (GnuPG/GPG)
GPG is used to identify yourself and authenticate your communications, including those with people you don't know. GPG allows anyone reading a GPG-signed email to verify its authenticity. In other words, GPG allows someone to be reasonably certain that communications signed by you actually are from you. GPG is useful because it helps prevent third parties from altering code or intercepting conversations and altering the message.
To participate in any part of the Fedora Project,
- You must have a GPG key pair.
- Your public key must be available on pgp.mit.edu.
