Windows客户端配置GitHub的SSH公钥

检查SSH keys的设置

$ cd ~/.ssh/

如果显示”No such file or directory”，跳到第三步，否则继续。

备份和移除原来的SSH key设置

如果已经存在key文件，需要备份该数据并删除之

$ ls
id_rsa  id_rsa.pub  known_hosts
$ mkdir key_backup
$ cp id_rsa* key_backup/
$ rm id_rsa*

生成新的SSH key

输入下面的代码，可以生成新的key文件，只需要使用默认的设置即可，当需要输入文件名的时候，回车即可

$ ssh-keygen -t rsa -C "你的邮箱@qq.com"
Generating public/private rsa key pair.
Enter file in which to save the key (/c/Users/WX/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /c/Users/WX/.ssh/id_rsa.
Your public key has been saved in /c/Users/WX/.ssh/id_rsa.pub.
The key fingerprint is:
1d:cc:7e:b3:7e:92:f7:ab:c6:75:56:73:62:30:bc:8c 你的邮箱@qq.com
The key's randomart image is:
+--[ RSA 2048]----+
|           .     |
|         o  +    |
|          +o +   |
|         oE.o o.o|
|        S o o. .+|
|           . o .o|
|            o....|
|           .ooo  |
|            o=.oo|
+-----------------+

Enter passphrase (empty for no passphrase):这里可以输入密码，在登录时验证

添加SSH key到GitHub

用文本编辑工具打开id_rsa.pub文件，如果看不到这个文件，你需要设置显示隐藏文件。准确的复制这个文件的内容，才能保证设置的成功。
在GitHub的主页上点击设置按钮，选择SSH Keys项，把复制的内容粘贴进去，然后点击Add Key按钮即可，Title任意选择。

测试一下

输入下面命令，测试是否设置成功（第一次登录）

$ ssh -T git@github.com
The authenticity of host 'github.com (192.30.255.112)' 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
Warning: Permanently added 'github.com,192.30.255.112' (RSA) to the list of know
n hosts.
Enter passphrase for key '/c/Users/dyf/.ssh/id_rsa':（如果上一步设置密码 这里需要输入）
Hi dyf007! You've successfully authenticated, but GitHub does not provide shell
access.
