生成&添加 SSH公钥
生成
-
打开 Terminal(终端)
-
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]-----+

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
- Gitee公钥管理页面: https://gitee.com/profile/sshkeys
- GitHub公钥管理页面: https://github.com/settings/keys
-
进入GitHub 或Gitee平台并打开设置
-
选择 SSH公钥
-
填写标题和公钥(id_ed25519.pub内容)
-
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.
