第一次通过 SSH key 免密连接 GitHub 的完整过程

原文：https://ichochy.com/posts/blog/20221107.html

通过密码连接GitHub总是要输入密码，麻烦，现在使用 SSH key 可以轻松实现免密验证.

创建 SSH key

使用 ssh-keygen 命令

  • 打开终端输入命令 ssh-keygen 创建 key
ssh-keygen -t ed25519 -C "ichochy@outlook.com"

注意：将ichochy@outlook.com换成自己的邮箱。

  • 命令构建ed25519 key，并自动保存到.ssh目录
Generating public/private ed25519 key pair.
Enter file in which to save the key (/Users/mleo/.ssh/id_ed25519): 
Created directory '/Users/mleo/.ssh'.
  • 提示输入key的密码
Enter passphrase (empty for no passphrase): 
Enter same passphrase again:

注意：可以输入空和密码

  • 提示key创建成功，并保存在.ssh目录
Your identification has been saved in /Users/mleo/.ssh/id_ed25519
Your public key has been saved in /Users/mleo/.ssh/id_ed25519.pub

配置 SSH key

  • 创建配置文件
touch ~/.ssh/config
  • 配置文件写入GitHub主机信息
Host github.com                           # 别名
	Hostname 	github.com                # GitHub 主机地址
	Port 		22                        # GitHub 主机端口
	User 		git                       # GitHub 主机用户
	Identityfile ~/.ssh/id_ed25519        # ssh-key
  • GitHub帐号中添加公钥key
iChochy(用户) => Settings => SSH and GPG keys => new SSH key

测试 SSH key

  • 测试 GitHub SSH 连接
ssh -T git@github.com
  • 确认是否连接
The authenticity of host 'github.com (20.205.243.166)' can't be established.
ED25519 key fingerprint is SHA256:+DiY3wvvV6TuJJhbpZisF/zLDA0zPMSvHdkr4UvCOqU.
This key is not known by any other names
Are you sure you want to continue connecting (yes/no/[fingerprint])?
  • 输入 yes确认连接
