最近又是換電腦，又是換硬碟的，來來回回搞了好幾次，遂記錄一下，最簡單的流程。

1.為什麼要用ssh？

平時用的是https連結，所以push等操作都得輸入使用者名稱密碼，很煩，但是認證了ssh連結之後，就可以在此臺機器上隨意操作專案了。

2.本地部署ssh

Windows：

cd ~/.ssh #進入ssh資料夾
ssh-keygen -t rsa -C "[email protected]" #建立ssh key
...
#回車使用預設檔名
Enter file in which to save the key (/c/Users/you/.ssh/id_rsa): [Press enter]
#回車使用空密碼
Enter passphrase (empty 
 
for no passphrase): 
Enter same passphrase again:
...
#出現如下表示建立成功
Your public key has been saved in /c/Users/you/.ssh/id_rsa.pub.

#檢視公鑰
cat id_rsa.pub

#複製命令列顯示的公鑰

3.GitHub新增ssh

進入setting

4.測試ssh

ssh -T [email protected]
...
Are you sure you want to continue connecting (yes/no)?
#輸入yes回車
Enter passphrase for
 
 key '/c/Users/Administrator/.ssh/id_rsa':
#繼續回車
Hi username! You've successfully authenticated, but GitHub does not provide shell access.

大功告成~
