C:Usersdphudy>ssh-keygen -t rsa -C "2921832035@qq.com"
'ssh-keygen' 不是内部或外部命令，也不是可运行的程序
或批处理文件。
解决办法一、设置环境变量
参考：https://www.cnblogs.com/e0yu/p/8508009.html
Git安装路径 D:Program FilesGitusrin
设置完成
结果：重新执行失败,可能需要重启变量才会生效或者路径设置错误。
解决办法二、ssh.exe 根目录下执行命令
C:Usersdphudy> cd D:Program FilesGitusrin
C:Usersdphudy>D:
D:Program FilesGitusrin>ssh-keygen -t rsa -C "2921832035@qq.com";
Generating public/private rsa key pair.
Enter file in which to save the key (/c/Users/dphudy/.ssh/id_rsa):
生成/添加SSH公钥
按照提示完成三次回车，即可生成 ssh key。
D:Program FilesGitusrin>ssh-keygen -t rsa -C "2921832035@qq.com";
Generating public/private rsa key pair.
Enter file in which to save the key (/c/Users/dphudy/.ssh/id_rsa):
Created directory '/c/Users/dphudy/.ssh'.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /c/Users/dphudy/.ssh/id_rsa
Your public key has been saved in /c/Users/dphudy/.ssh/id_rsa.pub
The key fingerprint is:
SHA256:Mcook4KNWm5Sge+PUQuVv4q0bR7bvZwlwBCLEFBJHhE 2921832035@qq.com;
The key's randomart image is:
+---[RSA 3072]----+
|=+E+. |
| +.o + |
|. + = o |
|.+ + * . o |
|+ X o * S |
|.* = . o |
|o * o . . . |
| + B.= o + |
| +o* . =. |
+----[SHA256]-----+
使用文本编辑器打开将KEY添加
添加后，在终端（Terminal）中输入 ssh -T git@gitee.com
dphudy@dp071708004 MINGW64 ~
$ ssh -T git@gitee.com
The authenticity of host 'gitee.com (180.97.125.228)' can't be established.
ECDSA key fingerprint is SHA256:FQGC9Kn/eye1W8icdBgrQp+KkGYoFgbVr17bmjey0Wc.
Are you sure you want to continue connecting (yes/no/[fingerprint])? yes

Hi 小岳! You've successfully authenticated, but GITEE.COM does not provide shell access.
首次使用需要确认并添加主机到本机SSH可信列表。若返回 Hi XXX! You've successfully authenticated, but Gitee.com does not provide shell access. 内容，则证明添加成功。
