Generating a new GPG key

Algoritmos compatibles de llave GPG

GitHub Enterprise es compatible con varios algoritmos GPG. Si tratas de agregar una llave generada con un algoritmo no compatible, puedes llegar a un error.

• RSA
• ElGamal
• DSA
• ECDH
• ECDSA
• EdDSA

Generating a GPG key

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. Abre la 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. Your key must use RSA.

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

     $ 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.

     $ 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 RSA and RSA.

5. Enter the desired key size. Your key must be at least 4096 bits.

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.

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. Utiliza el comando gpg --list-secret-keys --keyid-format LONG para enumerar las llaves GPG para las cuales tienes tanto una llave pública como privada. Se requiere una llave privada para registrar confirmaciones o etiquetas.

    $ gpg --list-secret-keys --keyid-format LONG

    Nota: Algunas instalaciones GPG en Linux pueden requerir que uses gpg2 --list-keys --keyid-format LONG para visualizar una lista de tus llaves existentes en su lugar. En este caso también deberás configurar Git para que use gpg2 by running git config --global gpg.program gpg2.

11. De la lista de llaves GPG, copia la ID de la llave GPG que quieres utilizar. En este ejemplo, el ID de la llave GPG es 3AA5C34371567BD2:

    $ gpg --list-secret-keys --keyid-format LONG
    /Users/hubot/.gnupg/secring.gpg
    ------------------------------------
    sec   4096R/3AA5C34371567BD2 2016-03-10 [expires: 2017-03-10]
    uid                          Hubot 
    ssb   4096R/42B317FD4BA89E7A 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:

    $ 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.
