本文详细介绍了如何使用sshgen生成SSH密钥对，并将其保存于~/.ssh目录下，包括私钥(id_rsa)与公钥(id_rsa.pub)。阐述了如何上传公钥至GitHub服务器，以及通过设置权限确保密钥安全。最后，通过实例展示了如何利用SSH密钥进行GitHub认证，实现免密码克隆仓库。

1. ssh gen saved in ~/.ssh

~/.ssh/

-rw------- 1 lake lake 1743 Mar 2 10:02 id_rsa ==========> Private key
-rw-r--r-- 1 lake lake 401 Mar 2 10:02 id_rsa.pub ============> Public key
-rw-r--r-- 1 lake lake 9946 Mar 2 10:26 known_hosts =================> Know hosts public key files from the 3rd party
2. upload ssh public key into git server

~/.ssh/id_rsa.pub ======> github.com/yourname =====> Setting ===> SSH public key upload

3. Test
