$ ssh-keygen.exe
generating public/private rsa key pair.
enter file in which to save the key (/c/users/17982/.ssh/id_rsa):
enter passphrase (empty for no passphrase):
enter same passphrase again:
your identification has been saved in /c/users/17982/.ssh/id_rsa.
your public key has been saved in /c/users/17982/.ssh/id_rsa.pub.
the key fingerprint is:
sha256:snym89sjwzx/wsdoa6ajyhm5ysayeeagw0l4 1782@desktop-4fr0rkp
the key's randomart image is:
+---[rsa 3072]----+
|==o . oo         |
|.o.. o.+.        |
|+.* o.=          |
|o=.= +.b         |
|+ o.o b.s        |
|o+e= o+= +       |
|..o.*=  + o      |
|  . o.   .       |

将公钥上传到服务器

$ ssh-copy-id zxc@zhangxuechao.top
/usr/bin/ssh-copy-id: info: source of key(s) to be installed: "/c/users/17982/.ssh/id_rsa.pub"
/usr/bin/ssh-copy-id: info: attempting to log in with the new key(s), to filter out any that are already installed
/usr/bin/ssh-copy-id: info: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys
zxc@zhangxuechao.top's password:

number of key(s) added: 1

now try logging into the machine, with:   "ssh 'zxc@zhangxuechao.top'"
and check to make sure that only the key(s) you wanted were added.
