生成&添加 SSH公钥

生成&添加 SSH公钥



生成

  1. 打开 Terminal(终端)

  2. 生成命令

    ssh-keygen -t ed25519 -C "your_email@example.com"
    

    note:如果您使用的是不支持 Ed25519 算法的旧系统,请使用 RSA,感兴趣的可以点击Ed25519和 RSA详情入口了解;

    • 参数解释:

      • -t: 指定使用的数字签名算法;
      • -C: 注释,随便填;
      • -f: 指定文件输出位置,可选默认为 ~/.ssh/
    • 输出日志(三次回车)

    Generating public/private ed25519 key pair.
    Enter file in which to save the key (/home/noname/.ssh/id_ed25519):     # 按回车键, 接受默认文件位置
    Enter passphrase (empty for no passphrase): # 按回车键, 设置空密码
    Enter same passphrase again:    # 按回车键
    Your identification has been saved in /home/noname/.ssh/id_ed25519
    Your public key has been saved in /home/noname/.ssh/id_ed25519.pub
    The key fingerprint is:
    SHA256:3tUVjse1MusYmzxShrReusMp2Rdd2NSTGSi3dBOujHA librarookie
    The key's randomart image is:
    +--[ED25519 256]--+
    |              .+B|
    |           . +=B=|
    |         o E++**+|
    |        . = o+*+ |
    |        So *o+o  |
    |       ...*o*.   |
    |        =+o*..   |
    |       o =o..    |
    |        ..o      |
    +----[SHA256]-----+
    
  3. 查看生成的 SSH keys

    • 查看公钥

      # 不出意外,~/.ssh/目录下应该有了 id_ed25519和 id_ed25519.pub
      # 我们打开 id_ed25519.pub
          cat ~/.ssh/id_ed25519.pub
      
      # 然后就可以看到公钥内容了(一串字符串)
      
    • 添加识别 SSH keys 新的私钥(可选,没识别到执行此步)

      ssh-agent bash
      ssh-add ~/.ssh/id_ed25519
      

      note: 默认只读取 id_rsa,为了让 SSH 识别新的私钥,需要将新的私钥加入到 ssh-agent 中


添加

  1. 进入GitHub 或Gitee平台并打开设置

  2. 选择 SSH公钥

  3. 填写标题和公钥(id_ed25519.pub内容)

  4. 输入密码


验证

打开Git Bash并输入

  • 验证命令

    ssh -T git@github.com   # github
    ssh -T git@gitee.com    # gitee
    
  • 成功输出

        # GitHub
    You've successfully authenticated, but GitHub does not provide shell access.
    
        # Gitee
    You've successfully authenticated, but GITEE.COM does not provide shell access.
