Связывание адреса электронной почты с ключом GPG

1. Open TerminalTerminalGit Bash.

2. 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.

3. 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
   

4. Enter gpg --edit-key GPG key ID, substituting in the GPG key ID you'd like to use. In the following example, the GPG key ID is 3AA5C34371567BD2:

   gpg --edit-key 3AA5C34371567BD2
   

5. Enter gpg> adduid to add the user ID details.

   gpg> adduid
   

6. Follow the prompts to supply your real name, email address, and any comments. You can modify your entries by choosing N, C, or E.

   Real Name: OCTOCAT
   Email address: "octocat@github.com"
   Comment: GITHUB-KEY
   Change (N)ame, (C)omment, (E)mail or (O)kay/(Q)uit?
   

7. Enter O to confirm your selections.

8. Enter your key's passphrase.

9. Enter gpg> save to save the changes

   gpg> save
   

10. Enter gpg --armor --export GPG key ID, substituting in the GPG key ID you'd like to use. In the following example, the GPG key ID is 3AA5C34371567BD2:

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

11. Upload the GPG key by adding it to your GitHub account.
