今天使用git clone命令報錯了，就是祕鑰過期了，重新生成新增到github伺服器就好了，步驟如下：

• 刪除.ssh資料夾）下的known_hosts檔案，在C盤的使用者目錄下，我的路徑

C:\Users\LUMIN\.ssh

• 開啟gitbash工具輸入命令

ssh-keygen -t rsa -C "username"

成功後返回以下確認資訊：

Generating public/private rsa key pair.
Enter file in which to save the key (/c/Users/LUMIN/.ssh/id_rsa):

回車鍵繼續，因為以前有這個檔案儲存了祕鑰資訊，所以會返回覆蓋的確認資訊如下：

/c/Users/LUMIN/.ssh/id_rsa already exists.
Overwrite (y/n)? 

輸入y，回車繼續，因為以前沒有儲存地址，返回以下資訊：

Enter passphrase (empty for no passphrase):

再次回車，返回再次確認資訊：

Enter same passphrase again:

回車確認，返回以下資訊，表示已生成SSH Key

Your identification has been saved in /c/Users/LUMIN/.ssh/id_rsa.
Your public key has been saved in /c/Users/LUMIN/.ssh/id_rsa.pub.
 

找到自動在.ssh資料夾下的id_rsa.pub，把內容複製到github的SSH Key中

最後輸入ssh -T [email protected]，測試是否成功，輸入yes，繼續連線：

The authenticity of host 'github.com (52.74.223.119)' can't be established.
RSA key fingerprint is SHA256:nThbg6kXUpJWGl7E1IGOCspRomTxdCARLviKw6E5SY8.
Are you sure you want to continue connecting (yes/no/[fingerprint])? yes

 

以下資訊成功

Warning: Permanently added 'github.com,52.74.223.119' (RSA) to the list of known hosts.
