Associating an email with your GPG key

Your GPG key must be associated with a GitHub Enterprise Server verified email that matches your committer identity.

If you're using a GPG key that matches your committer identity and your verified email address associated with your account on your GitHub Enterprise Server instance, then you can begin signing commits and signing tags.

  1. 打开终端终端Git Bash

  2. 使用 gpg --list-secret-keys --keyid-format=long 命令列出你拥有其公钥和私钥的长形式 GPG 密钥。 签名提交或标记需要私钥。

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

    注意:Linux 上的某些 GPG 安装可能需要改用 gpg2 --list-keys --keyid-format LONG 查看现有密钥的列表。 在这种情况下,还需要通过运行 git config --global gpg.program gpg2 来配置 Git 以使用 gpg2

  3. 从 GPG 密钥列表中复制您想要使用的 GPG 密钥 ID 的长形式。 在本例中,GPG 密钥 ID 为 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/42B317FD4BA89E7A 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.
