gitHub添加公钥

gitHub添加公钥

1. gitHub是通过SSH公钥连接到现有仓库的

2. 设置SSH Key

   ssh-keygen -t rsa -C "your_email@example.com"
   Generating public/private rsa key pair.
   Enter file in which to save the key (/Users/mouMiFan/.ssh/id_rsa): //Enter 回车
   Enter passphrase (empty for no passphrase): //密码
   Enter same passphrase again: //密码
   

   结果：

   Your identification has been saved in /Users/mouMiFan/.ssh/id_rsa.
   Your public key has been saved in /Users/mouMiFan/.ssh/id_rsa.pub.
   The key fingerprint is:
   SHA256:OkZCZO3AEOTsBILDqS/RZQhmr/YW2KVMExtdFOHmZh0 your_email@example.com
   The key's randomart image is:
   +---[RSA 2048]----+
   |*==B+.o=o        |
   |**ooO.o          |
   |.o+B.+ o E       |
   |ooB.+ + . .      |
   | *.=. .+S.       |
   |o o .oo.         |
   | . o  +          |
   |  .  . .         |
   |                 |
   +----[SHA256]-----+
   

   在~/.ssh 文件夹中便生成了文件:
   id_rsa 文件是私有密钥，id_rsa.pub 是公开密钥。

3. 查看公钥

   cat ~/.ssh/id_rsa.pub
   
   ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQC4y3M40TOWuHhEraguOtunMtzywSre2ZcsvFUIAQ7DDPkp+pX4Su0RpYaqIvKm4JHy2f3+IsnlbThAJQkbJ4UC8YufHsk7h+bvjnb7P4lQGvbgHTu4zt2xrOBc3XiJrO+bCJLHwzdaVR8qE+uzwEaSE5b+VqH4xZt58yOBV4e2/fCBvlSnOqwuCMdaRNi2HnB1C+TEoEWFfJQxrgFWW1eEwbfwA/g4bkL9jNz8VVPnYRI6kZiVHIA6SLHmVzDdVCy0WgqKFUIkUVPSviahWdFV73IyMIvGt+s1FtE90iKIVH4SBIUrhhbxgHgX6Vgpv6qo2o1QJUqMW23cGwUfALrL your_email@example.com
   

4. 提交到gitHub

   打开 https://github.com/settings/ssh，点击New SSH Key按钮，粘贴上面的公钥保持即可
