没有配置ssh之前不能复制ssh链接：

    先到用户的主页目录，删除.ssh文件夹（如果没有.ssh文件夹，忽略此步）：

    在Git里面运行命令ssh-keygen生成.ssh目录：
    -t后面加加密算法，-C（必须大写）后面加邮箱，执行命令后再加三个回车

    1. abc@DESKTOP-R85C9HV MINGW64 ~/Desktop/HelloGit-clone/HelloGit (master)
    2. $ ssh-keygen -t rsa -C abc@123.com
    3. Generating public/private rsa key pair.
    4. Enter file in which to save the key (/c/Users/abc/.ssh/id_rsa):
    5. Created directory '/c/Users/abc/.ssh'.
    6. Enter passphrase (empty for no passphrase):
    7. Enter same passphrase again:
    8. Your identification has been saved in /c/Users/abc/.ssh/id_rsa
    9. Your public key has been saved in /c/Users/abc/.ssh/id_rsa.pub
    10. The key fingerprint is:
    11. SHA256:aeNMB/hP2yiH/Dka2jK9BJciSgA8yKKLlKXX8oei7J0 jallenkwong@163.com
    12. The key's randomart image is:
    13. +---[RSA 3072]----+
    14. |=                |
    15. |++ .   .         |
    16. |+ = . . .        |

    25. abc@DESKTOP-R85C9HV MINGW64 ~
    26. $ ls -a .ssh
    27. ./  ../  id_rsa  id_rsa.pub
    29. # 生成公钥
    30. abc@DESKTOP-R85C9HV MINGW64 ~
    31. $ cat .ssh/id_rsa.pub
    32. ssh-rsa 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 abc@123.com

    然后，将生成的公钥添加至Github账号SSH设置

    添加公钥后，可不用输入Github账号密码便可推送。
    接下来通过SSH方式提交hello.txt。
