Windows下生成GitHub/Gitee SSH key

前提：已安装git。
1、输入以下命令生成ssh key，一路回车即可。（xxxx@xxx.com为你注册GitHub的邮箱）（注意，Gitee只需这一步，然后复制密码就好）
GitHub：ssh-keygen -t rsa -C "xxxx@xxx.com"
Gitee：ssh-keygen -t ed25519 -C "xxxx@xxx.com"

1. $ ssh-keygen -t rsa -C  "xxxx@xxx.com"
2. Generating public/private rsa key pair.
3. Enter file in which to save the key (/c/Users/Administrator/.ssh/id_rsa):
4. Enter passphrase (empty for no passphrase):
5. Enter same passphrase again:
6. Your identification has been saved in /c/Users/Administrator/.ssh/id_rsa
7. Your public key has been saved in /c/Users/Administrator/.ssh/id_rsa.pub
8. The key fingerprint is:
9. SHA256:/ydX+AEdhH+HOukbM2knJNHjaa+vPhctxE70hDJv4ys  "xxxx@xxx.com"
10. The key's randomart image is:
11. +---[RSA 3072]----+
12. |              oo |
13. |           .o.o..|
14. |          . o*o+.|
15. |           o +Oo+|
16. |        S . =O.+o|
17. |         . ++o*.o|
18. |          ..B.o*.|
19. |           oEB= .|
20. |           .*@.  |
21. +----[SHA256]-----+

复制代码

2、输入命令：eval "ssh-agent -s"

1. $ eval "ssh-agent -s"
2. SSH_AUTH_SOCK=/tmp/ssh-pdrfl8Q4DvbK/agent.585; export SSH_AUTH_SOCK;
3. SSH_AGENT_PID=586; export SSH_AGENT_PID;
4. echo Agent pid 586;

复制代码

3、继续输入命令：ssh-add ~/.ssh/id_rsa

1. $ ssh-add ~/.ssh/id_rsa
2. Identity added: /c/Users/Administrator/.ssh/id_rsa (xxxx@xxx.com)

复制代码

如果报错（Could not open a connection to your authentication agent.），则需要先执行命令：ssh-agent bash，再执行上述命令
 
4、复制生成的key到GitHub
查看key：cat ~/.ssh/id_rsa.pub（Gitee：$ cat .ssh/id_ed25519.pub）

1. $ cat ~/.ssh/id_rsa.pub
2. ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABgQCbLVIplXKxgdi2fi2ZhPW6o5dtF/mSeE3CmlFxmfUDoDgPaQDqebEiOaBNBN1GYvcpQxLXTkRuA9g7nf8DnH3qKfUq98QftsxbAcwvH1Xr0EcJFakMx7d0pGFH1RQ/kVr1iU3kKU4wuKhQn73Momje18BormKovP5InObSWNu7TAtkhmgF43W31NJjqS+mJ9v62Y7r65uetUgRwv9+MGJP3CO62TTLjdIom8VpK5uch7EGm3x6FYt8VT3urZS/ji/ixlvKaRJ7X1MJrCbQQ+8EfHejpKhQxZ0HU3p8CIjdbL1d9j1wIc8kz11zrEaoNSPdwK9J8pnl2o+TjoNQIUvNd0JHDsosCZARB0tzmuS0WnA3VvoldcIsMBfGC52bKW/zWuKkSUS0j+BTDvyk3aaS//ITmCnwffQeBo8C3A59KY00bEGDAWjhWhxJvQAhw3Qum7bZTIrC/glhwSxOcFSSEh0gu9hLLLQ2iq5CiNfbNv8/JpTPIDp/G+irUQ7URrE= "xxxx@xxx.com"

复制代码

GitHub位置如下：

 
 
 
5、检查是否成功：
ssh -T "git@github.com" （Gitee：ssh -T git@gitee.com）

1. GitHub的连不上，Gitee倒是连上了

复制代码

$ ssh -T git@gitee.com
The authenticity of host 'gitee.com (212.64.63.215)' can't be established.
ED25519 key fingerprint is SHA256:+ULzij2u99B9eWYFTw1Q4ErYG/aepHLbu96PAUCoV88.
This key is not known by any other names
Are you sure you want to continue connecting (yes/no/[fingerprint])? yes
Warning: Permanently added 'gitee.com' (ED25519) to the list of known hosts.
Hi mikasama! You've successfully authenticated, but GITEE.COM does not provide shell access.
