用ssh-keygen生成公匙和私钥
d:\c\learnc>ssh-keygen
Generating public/private rsa key pair.
Enter file in which to save the key (/c/Users/Mize/.ssh/id_rsa):
Created directory ‘/c/Users/Mize/.ssh‘.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /c/Users/Mize/.ssh/id_rsa.
Your public key has been saved in /c/Users/Mize/.ssh/id_rsa.pub.
The key fingerprint is:
d7:67:5a:c8:6a:ba:3a:62:0e:b3:2c:b9:af:62:4c:cf [email protected]
id_rsa.pub是公匙，id_rsa是私匙，粘贴公匙给github
https://github.com/settings/keys
测试ssh连接，核对github的公匙指纹
github的指纹为：https://help.github.com/articles/what-are-github-s-ssh-key-fingerprints/
d:\c\learnc>ssh [email protected]
The authenticity of host ‘github.com (192.30.252.121)‘ can‘t be established.
RSA key fingerprint is 16:27:ac:a5:76:28:2d:36:63:1b:56:4d:eb:df:a6:48.
Are you sure you want to continue connecting (yes/no)? yes

Hi mizegit! You‘ve successfully authenticated, but GitHub does not provide shell
access.
Connection to github.com closed.
如果没添加过远程仓库就添加
git remote add origin https://github.com/user/repo.git
参考：https://help.github.com/articles/adding-a-remote/
如果之前为https方式的仓库就，替换https为ssh，ssh方式地址在github仓库网页上可以复制。
d:\c\learnc>git remote -v
origin https://github.com/mizegit/learnc.git (fetch)
origin https://github.com/mizegit/learnc.git (push)
d:\c\learnc>git remote set-url origin [email protected]:mizegit/learnc.git
d:\c\learnc>git remote -v
origin [email protected]:mizegit/learnc.git (fetch)
origin [email protected]:mizegit/learnc.git (push)
下次git push origin master就不会提示输入账号密码了，
https也可以通过修改配置避免输入账号密码：
git remote set-url origin https://[userName]:[password]@github.com/[username]/project.git
