- GPG (GNU Privacy Guard) is a free, open-source tool for encrypting and signing data using symmetric-key and public-key cryptography.
- GPG is used to secure email communications, verify software package integrity, and sign git commits to prevent impersonation.
- Generating a GPG key involves choosing algorithms like ED25519, setting key validity, and securing it with a passphrase.
- Git can be configured to sign commits with a GPG key, enhancing repository security by verifying commit authenticity.
- Trust levels for GPG keys can be set to 'ultimate' to ensure the key is fully trusted for signing and encryption.
