当我们想把项目push到GitHub上时，需要为本机添加密钥，下面介绍如何生成SSH密钥
Linux下生成SSH密钥
把邮件地址换成自己的邮件地址，输入命令一路回车就可以了
[fogfore@localhost www]$ ssh-keygen -t rsa -C "你的邮件地址"
Generating public/private rsa key pair.
Enter file in which to save the key (/home/fogfore/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/fogfore/.ssh/id_rsa.
Your public key has been saved in /home/fogfore/.ssh/id_rsa.pub.
The key fingerprint is:
43:ef:9e:42:ea:45:d8:13:dd:41:32:93:8b:e0:50:39 [email protected]
The key's randomart image is:
+--[ RSA 2048]----+
| ... +oo |
| . E ..= . |
| o oo.... |
| .+.o. |
| . S . |
| ..+ |
| o. . |
| .... . |
| .. .o |

Window下生成SSH密钥
window下用Git Bash生成密钥，方法参考Linux下生成密钥
添加密钥到GitHub
将.ssh/id_rsa.pub里的内容复制到GitHub
