添加ssh密钥

直接运行ssh-keygen，可以不输入密码

$ ssh-keygen
Generating public/private rsa key pair.
Enter file in which to save the key (/c/Users/Administrator/.ssh/id_rsa):
/c/Users/Administrator/.ssh/id_rsa already exists.
Overwrite (y/n)? y
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:OIS9QLytpU09WUT0sMCcMs70JozqWjj1ivcEmadjjKk Administrator@-
The key's randomart image is:
+---[RSA ]----+
|   ..  o.==      |
|   ..o+ +..+     |
|    oOo= o. .    |
|   oooOo*        |
|  =..*+oS.       |
| *.=o ..         |
|=.* o            |
|.=o+             |
|Eo...            |
+----[SHA256]-----+

而后在如下路径/c/Users/Administrator/.ssh会有id_rsa.pub文件，将其中的内容复制添加到如下位置，则可。
