Supported GPG key algorithms

GitHub Enterprise Server 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

Generating a GPG key

Note

Before generating a new GPG key, make sure you've verified your email address. If you haven't verified your email address, you won't be able to sign commits and tags with GPG.

  1. Download and install the GPG command line tools for your operating system. We generally recommend installing the latest version for your operating system.

  2. Open TerminalTerminalGit Bash.

  3. Generate a GPG key pair. Since there are multiple versions of GPG, you may need to consult the relevant man page to find the appropriate key generation command.

    • If you are on version 2.1.17 or greater, paste the text below to generate a GPG key pair.

      Shell
      gpg --full-generate-key

    • If you are not on version 2.1.17 or greater, the gpg --full-generate-key command doesn't work. Paste the text below and skip to step 6.

      Shell
      gpg --default-new-key-algo rsa4096 --gen-key

  4. At the prompt, specify the kind of key you want, or press Enter to accept the default.

  5. At the prompt, specify the key size you want, or press Enter to accept the default.

  6. Enter the length of time the key should be valid. Press Enter to specify the default selection, indicating that the key doesn't expire. Unless you require an expiration date, we recommend accepting this default.

  7. Verify that your selections are correct.

  8. Enter your user ID information.

    Note

    When asked to enter your email address, ensure that you enter the verified email address for your GitHub account.

  9. Type a secure passphrase.

  10. Use the gpg --list-secret-keys --keyid-format=long command to list the long form of the GPG keys for which you have both a public and private key. A private key is required for signing commits or tags.

    Shell
    gpg --list-secret-keys --keyid-format=long

    Note

    Some GPG installations on Linux may require you to use gpg2 --list-keys --keyid-format LONG to view a list of your existing keys instead. In this case you will also need to configure Git to use gpg2 by running git config --global gpg.program gpg2.

  11. From the list of GPG keys, copy the long form of the GPG key ID you'd like to use. In this example, the GPG key ID is 3AA5C34371567BD2:

    Shell
    $ gpg --list-secret-keys --keyid-format=long
/Users/hubot/.gnupg/secring.gpg
------------------------------------
sec   4096R/3AA5C34371567BD2 2016-03-10 [expires: 2017-03-10]
uid                          Hubot <hubot@example.com>
ssb   4096R/4BB6D45482678BE3 2016-03-10

  12. Paste the text below, substituting in the GPG key ID you'd like to use. In this example, the GPG key ID is 3AA5C34371567BD2:

    Shell
    gpg --armor --export 3AA5C34371567BD2
# Prints the GPG key ID, in ASCII armor format

  13. Copy your GPG key, beginning with -----BEGIN PGP PUBLIC KEY BLOCK----- and ending with -----END PGP PUBLIC KEY BLOCK-----.

  14. Add the GPG key to your GitHub account.
