一、生成密钥
大多数 Git 服务器都会选择使用 SSH 公钥来进行授权。系统中的每个用户都必须提供一个公钥用于授权，没有的话就要生成一个。生成公钥的过程在所有操作系统上都差不多。首先你要确认一下本机是否已经有一个公钥。
.ssh文件夹默认存放位置为：C:\Users\Administrator\.ssh
有的话直接把里面的文件都删了,我是这么做的哈。
然后命令行输入：
#ssh-keygen -t rsa -C "填注册git时的邮箱如12157084@qq.com" 如下表示生成成功
$ ssh-keygen -t rsa -C "dmin@example.co"
Generating public/private rsa key pair.
Enter file in which to save the key (/c/Users/Administrator/.ssh/id_rsa):
Created directory '/c/Users/Administrator/.ssh'.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Passphrases do not match. Try again.
Enter passphrase (empty for no passphrase):

Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /c/Users/Administrator/.ssh/id_rsa.
Your public key has been saved in /c/Users/Administrator/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:XkEhwQH21tRl7EMD6qYTjQA6MIdW/l+I2rumIKzrLi8 a”dmin@example.com
The key's randomart image is:
+---[RSA 3072]----+
