ssh建立github连接 基于ssh密钥

1. 建立公钥和私钥

ps：公钥放在github上面的，私钥放在自己本地电脑 ；

先生成密钥：打开 gitbash 输入命令：

ssh-keygen -t rsa -b 4096 -C "zhulongxu2022@163.com"

中间会让你输入东西不用管，直接一直回车 ；

结果：

Generating public/private rsa key pair.
Enter file in which to save the key (/c/Users/zhulo/.ssh/id_rsa):
Created directory '/c/Users/zhulo/.ssh'.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /c/Users/zhulo/.ssh/id_rsa
Your public key has been saved in /c/Users/zhulo/.ssh/id_rsa.pub
The key fingerprint is:
SHA256:zrhuxX/87PmZODzZq1lGIn7TTq1Fqzh0v4IlcAscftI zhulongxu2022@163.com
The key's randomart image is:
+---[RSA 4096]----+
|                 |
|         .       |
|        o o      |
|         * E     |
|       .S *... ..|
|       +o .+.o+.o|
|      ..o..o*o+*o|
|      ..  .o=BX*o|
|     oo    o.B@B+|
+----[SHA256]-----+

有如上代码表示成功；

结果就是生成了密钥并保存在  C:\Users\zhulo\.ssh 里面 ；

2. 将SSH密钥添加到ssh-agent

输入 eval 回车

输入 ssh-agent -s 回车

3. 把ssh添加到账户

输入 ssh-agent bash

输入 ssh-add ~/.ssh/id_rsa

如下结果出现则说明成功 ；

4. 把公钥复制到github上面

使用命令 cat ~/.ssh/id_rsa.pub

把这段文字复制到github的新增密钥上面保存即可 ；

终端输入：ssh -T git@github.com

显示：

The authenticity of host 'github.com (20.205.243.166)' can't be established.
ECDSA key fingerprint is SHA256:p2QAMXNIC1TJYWeIOttrVc98/R1BUFWu3/LiyKgUfQM.
Are you sure you want to continue connecting (yes/no/[fingerprint])?

选择  yes 回车 显示如下；

Warning: Permanently added 'github.com,20.205.243.166' (ECDSA) to the list of known hosts.
Hi xxxxxx You've successfully authenticated, but GitHub does not provide shell access.

ps：如果 xxxxx 如果是你的 github 账号名说明ssh建立成功 ；
