Github添加SSH keys

打开终端
1.输入指令：

cd ~/.ssh

2.ls 查看该目录下文件
config id_rsa id_rsa.pub known_hosts
如果有这些说明本地已经有创建SSH
3.创建SSH key

ssh-keygen -t rsa -C "xxx@xxx.com"  填自己GitHub上的邮箱

Generating public/private rsa key pair.
Enter file in which to save the key (/Users/xxx/.ssh/id_rsa):
接下来会提示你输入密码，这个密码是用来每次提交的时候输入确认，(可以不设置，两次回车)

此处因本人已经设置过SSHKey，所以此次操作变成了替换
/Users/xxx/.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 /Users/xxx/.ssh/id_rsa.（id存在的位置）
Your public key has been saved in /Users/xxx/.ssh/id_rsa.pub. (私有key所存在的位置)

5.看到显示结果

The key fingerprint is:
SHA256:5zRejkXCViVHm9xBnRvWEq5eE7swJ8soOexnylXuXB4 xxx@xxx.com
The key's randomart image is:
+---[RSA 3072]----+
|            oo*++|
|         . . =.B+|
|          + . B.+|
|         . o . + |
|        S + O =  |
|       . * % B o |
|        = * * E  |
|       o +oo o . |
|        ++  o .  |
+----[SHA256]-----+

最后成功后会看到类似如下的输出，表示成功生成SSH key了，可以在/.ssh文件夹下看下

6. cat id_rsa.pub
   看到如下结果

ssh-rsa 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 xxx@xxx.com

//这就是你的key值了
