1.Windows下生成.ssh檔案，若已經生成，則找到該檔案；

   開啟git 命令列：ls -al ~/.ssh    來檢視是否有ssh key存在；

  檢查/.ssh目錄來檢視是否存在公開的ssh key

  一般而言，公開的ssh key的檔名為以下幾種：

• id_dsa.pub
• id_ecdsa.pub
• id_ed25519.pub
• id_rsa.pub 

   建立一個 SSH key ：

   在你檢查過存在的ssh key後，你可以新建一個ssh key：    開啟Git Bash    輸入這一串：“ ” 中的內容為公司分配的個人郵箱/自己的郵箱

$ ssh-keygen -t rsa -C "
 
[email protected]"

生成了之後去你本地c://使用者名稱//.ssh資料夾下找有兩個檔案，把pub打開復制到github上；

2.測試一下該SSH key

ssh -T [email protected] 

[email protected] MINGW64 ~
$ ls -al ~/.ssh
ls: cannot access '/c/Users/hasee/.ssh': No such file or directory

[email protected] MINGW64 ~
$ ssh-keygen -t rsa -C "[email protected]
 
"
Generating public/private rsa key pair.
Enter file in which to save the key (/c/Users/hasee/.ssh/id_rsa):
Created directory '/c/Users/hasee/.ssh'.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /c/Users/hasee/.ssh/id_rsa.
Your public key has been saved in /c/Users/hasee/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:5I/cwhM6Tps4xmgkAislERFhy1xqH0OsSWr5DrXYS9w 
 
[email protected]
The key's randomart image is:
