Before you generate a GPG key, you can check to see if you have any existing GPG keys.
Supported GPG key algorithms
GitHub Enterprise supports several GPG key algorithms. If you try to add a key generated with an unsupported algorithm, you may encounter an error.
- RSA
- ElGamal
- DSA
- ECDH
- ECDSA
- EdDSA, except Ed25519
Note: GPG does not come installed by default on OS X or Windows. To install GPG command line tools, see GnuPG's Download page.
Open TerminalTerminalGit Bash.
-
Use the
gpg --list-secret-keys --keyid-format LONGcommand to list GPG keys for which you have both a public and private key. A private key is required for signing commits or tags.gpg --list-secret-keys --keyid-format LONGNote: Some GPG installations on Linux may require you to use
gpg2 --list-keys --keyid-format LONGto view a list of your existing keys instead. In this case you will also need to configure Git to usegpg2by runninggit config --global gpg.program gpg2. -
Check the command output to see if you have a GPG key pair.
- If there are no GPG key pairs or you don't want to use any that are available for signing commits and tags, then generate a new GPG key.
- If there's an existing GPG key pair and you want to use it to sign commits and tags, then add your GPG key to your GitHub account.
