1. 通过命令 ssh-keygen 生成 SSH Key：

ssh-keygen -t ed25519 -C "Gitee SSH Key"

  • -t：key 类型

  • -C： 注释

输出，如：

Generating public/private ed25519 key pair.
Enter file in which to save the key (/home/git/.ssh/id_ed25519):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/git/.ssh/id_ed25519
Your public key has been saved in /home/git/.ssh/id_ed25519.pub
The key fingerprint is:
SHA256:ohDd0OK5WG2dx4gST/j35HjvlJlGHvihyY+Msl6IC8I Gitee SSH Key
The key's randomart image is:
+--[ED25519 256]--+
|    .o           |
|   .+oo          |
|  ...O.o +       |
|   .= * = +.     |
|  .o +..S*. +    |
|. ...o o..+* *   |
|.E. o . ..+.O    |
| . . ... o =.    |
|    ..oo. o.o    |
+----[SHA256]-----+

  • 中间通过三次回车键确定

  1. 查看生成的 SSH 公钥和私钥：

ls ~/.ssh/

输出：

id_ed25519  id_ed25519.pub

  • 私钥文件 id_ed25519

  • 公钥文件 id_ed25519.pub

  1. 读取公钥文件 ~/.ssh/id_ed25519.pub：

cat ~/.ssh/id_ed25519.pub

输出，如：

ssh-ed25519 AAAA***5B Gitee SSH Key
