生成密钥对

$ ssh-keygen
Generating public/private rsa key pair.
Enter file in which to save the key (/c/Users/user/.ssh/id_rsa): ./id_rsa_ss1
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in ./id_rsa_ss1.
Your public key has been saved in ./id_rsa_ss1.pub.
The key fingerprint is:
SHA256:YgEqk6O7p8iQYc8Cxxxxxxxxxxzqu0UDCRkXeTJIDs user@DESKTOP-8LB6JPN
The key's randomart image is:
+---[RSA 3072]----+
|.=.o+o           |
|o.=o+..          |
...
