MAC添加GitHub SSH验证

查看本地是否已经存在SSH文件

ls -al ~/.ssh
# Lists the files in your .ssh directory, if they exist

生成SSH KEY

ssh-keygen -t rsa -b 4096 -C "[email protected]"

-C后面是生成的公有key标识，可以随意写。
生成的文件默认路径是/Users/you/.ssh/id_rsa,此处会询问是否添加密码，我直接跳过了。
you是你电脑的用户名。

添加SSH KEY到ssh-agent

因为我电脑版本是 macOS Sierra 10.12.6,所以直接通过~/.ssh/config管理。
在config中添加以下配置

# github server
# HOST是别名
Host github
# github地址
HostName github.com
# 此处直接填git
User git
# 私有key
IdentityFile ~/.ssh/id_rsa

添加本地公有key到github

复制id_rsa.pub的内容，在github的Setting > SSH and GPG keys > SSH keys按钮下新建一个SSH key，
并将内容粘贴到Key输入框中。至此所有操作完成。

测试SSH连接

ssh -T [email protected]
# Attempts to ssh to GitHub

如果看到以下警告

The authenticity of host 'github.com (IP ADDRESS)' can't be established.
RSA key fingerprint is 16:27:ac:a5:76:28:2d:36:63:1b:56:4d:eb:df:a6:48.
Are you sure you want to continue connecting (yes/no)?

The authenticity of host 'github.com (IP ADDRESS)' can't be established.
RSA key fingerprint is SHA256:nThbg6kXUpJWGl7E1IGOCspRomTxdCARLviKw6E5SY8.
Are you sure you want to continue connecting (yes/no)?

则输入yes。

Hi username! You've successfully authenticated, but GitHub does not
provide shell access.

看到以上提示信息表示连接成功。

此时clone或者提交代码时就不需要再输入密码了。但是要注意的是，clone的代码请选择Clone With SSH。
