由于你的本地 Git 仓库和 GitHub 仓库之间的传输是通过SSH加密的，所以我们需要配置验证信息

ssh-keygen -t rsa -C "youremail@example.com"

your_email@youremail.com 改为你在 Github 上注册的邮箱，之后会要求确认路径和输入密码，一直回车即可

$ ssh-keygen -t rsa -C "your_email@youremail.com"
Generating public/private rsa key pair.
Enter file in which to save the key (/Users/tianqixin/.ssh/id_rsa): 
Enter passphrase (empty for no passphrase):    # 直接回车
Enter same passphrase again:                   # 直接回车
Your identification has been saved in /Users/tianqixin/.ssh/id_rsa.
Your public key has been saved in /Users/tianqixin/.ssh/id_rsa.pub.
The key fingerprint is:                        # 直接回车
SHA256:MDKVidPTDXIQoJwoqUmI4LBAsg5XByBlrOEzkxrwARI 429240967@qq.com
The key's randomart image is:
+---[RSA 3072]----+
|E*+.+=**oo       |
|%Oo+oo=o. .      |
|%**.o.o.         |
|OO.  o o         |

+----[SHA256]-----+

成功的话会在~/下生成.ssh文件夹，进去，打开id_rsa.pub,复制里面的key

 回到github，点进你的头像，进入Settings

 验证成功

$ ssh -T git@github.com
