Key Differences and Overlaps between SSH keys and GPG keys
Table of Contents
Key Differences and Overlaps
Primary Function
SSH keys are primarily for authentication, while GPG keys are primarily for encryption, decryption, and signing.
Complexity
GPG keys are generally more complex than SSH keys, with features like subkeys and key expiration/revocation.
Interoperability
While distinct, GPG keys can be used for SSH authentication, providing a unified approach to key management for some users.
Commit Signing
Both GPG and SSH keys can be used to sign Git commits and tags for verification on platforms like GitHub. SSH commit signing is a more recent addition and often simpler to set up for this specific purpose.
