github设置SSH登录

1. 生成 SSH key

ssh-keygen -t ed25519 -C "your_email@example.com"

etjav@LAPTOP-3DC06KH4 MINGW64 ~/Desktop/finebi_demo (main)
$ ssh-keygen -t ed25519 -C 'xx@xx.com'
Generating public/private ed25519 key pair.
Enter file in which to save the key (/c/Users/etjav/.ssh/id_ed25519):
Created directory '/c/Users/etjav/.ssh'.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /c/Users/etjav/.ssh/id_ed25519.
Your public key has been saved in /c/Users/etjav/.ssh/id_ed25519.pub.
The key fingerprint is:
SHA256:x/3dqAWQZAz/T5o7G3PBA+rXa3h9Alki3etDECJWvAafk xx@xx.com
The key's randomart image is:
+--[ED25519 256]--+
|     ..o+=+      |
|      =. *o.o    |
|     . .o.+o.o   |
|       .E.o=oo.  |

|           .oB+.o|
|            +=...|
+----[SHA256]-----+

2. 将SSH Key添加到github

将生成的公钥（通常在 ~/.ssh/id_ed25519.pub）添加到 GitHub

登录 GitHub → Settings → SSH and GPG keys → New SSH key

3. 修改远程地址为 SSH

git remote set-url origin git@github.com:xxx/xxx.git

例如：git remote set-url origin git@github.com:etjava/etjava_demo.git

4. 推送到github

git push origin main

$ git push origin main
The authenticity of host 'github.com (140.82.112.4)' can't be established.
ECDSA key fingerprint is SHA256:p2QAMXNIC1TJYWeIOttrVc98/R1BUFWu3/LiyKgUfQM.
Are you sure you want to continue connecting (yes/no)? y
Please type 'yes' or 'no': yes
