前言

虽然Windows系统提供了凭据功能，但是介绍ssh提交，的免密操作

一、生成密钥

进入当前用户的目录
双击打开或者命令方式

Apple@DESKTOP-ECLNIU2 MINGW64 ~/Desktop
$ cd ~Apple@DESKTOP-ECLNIU2 MINGW64 ~
$ pwd
/c/Users/AppleApple@DESKTOP-ECLNIU2 MINGW64 ~
$

然后在当前文件夹下创建SSH 密钥

Apple@DESKTOP-ECLNIU2 MINGW64 ~
$ ssh-keygen -t rsa -C 18261897435@139.com
Generating public/private rsa key pair.
Enter file in which to save the key (/c/Users/Apple/.ssh/id_rsa):
Created directory '/c/Users/Apple/.ssh'.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /c/Users/Apple/.ssh/id_rsa
Your public key has been saved in /c/Users/Apple/.ssh/id_rsa.pub
The key fingerprint is:
SHA256:QEZzuGzZzFBRmmp+DSu0o1VXEvxp+0KpKjjrWfONv6M 18261897435@139.com
The key's randomart image is:
+---[RSA 3072]----+
|     .=o++o      |
|     ooo o..     |
|     ..Bo ....   |
|      =o+  o+    |
|     .+ S .. o   |
|     + o =  +    |
|     .O o .o .   |
|    o=.* oo . .  |
|   .=o .E++o .   |
+----[SHA256]-----+Apple@DESKTOP-ECLNIU2 MINGW64 ~
$

此时创建了.ssh文件夹和两个文件

二、使用步骤

1.使用VSCODE打开.pub文件复制其中的内容

2.打开github或者gitee进入设置选项设置密钥

选择SSH公钥

标题随便起，但要方便记忆
输入刚才vscode打开的密钥复制的key到公钥
点击确定

输入密码验证后就可以使用了

3.使用密钥

给SSH地址起一个别名
复制地址

给ssh地址起别名
如下（示例）：


Apple@DESKTOP-ECLNIU2 MINGW64 ~/Desktop/git basic operation/GitResp (master)
$ git remote -v
origin  https://gitee.com/gitee18261897435/git-resp.git (fetch)
origin  https://gitee.com/gitee18261897435/git-resp.git (push)Apple@DESKTOP-ECLNIU2 MINGW64 ~/Desktop/git basic operation/GitResp (master)
$ git remote add origin_ssh git@gitee.com:gitee18261897435/git-resp.gitApple@DESKTOP-ECLNIU2 MINGW64 ~/Desktop/git basic operation/GitResp (master)
$ git remote -v
origin  https://gitee.com/gitee18261897435/git-resp.git (fetch)
origin  https://gitee.com/gitee18261897435/git-resp.git (push)
origin_ssh      git@gitee.com:gitee18261897435/git-resp.git (fetch)
origin_ssh      git@gitee.com:gitee18261897435/git-resp.git (push)Apple@DESKTOP-ECLNIU2 MINGW64 ~/Desktop/git basic operation/GitResp (master)
$

别名起成功了
创建一个Test100.txt用于演示登录

注意第一次使用免密登录的时候需要输入一个yes

Apple@DESKTOP-ECLNIU2 MINGW64 ~/Desktop/git basic operation/GitResp (master)
$ git add Test100.txtApple@DESKTOP-ECLNIU2 MINGW64 ~/Desktop/git basic operation/GitResp (master)

因为没有进行远程库拉取，先拉取后再提交

检查远程库查看推送成功

总结

ssh的好处是：不用每次都进行身份验证缺陷：只能针对一个账号
