换电脑没办法使用git 下载项目的问题

换了一台电脑，安装了新的git工具

 

生成id_rsa.pub，把id_rsa.pub的内容加入到账号的ssh配置里面

 

本以为一切顺利，不过一下载就遇见如下问题

The authenticity of host '。。。。' can't be established.
ED25519 key fingerprint is SHA256:k4ViHJBFryacGI+BqHphyjDBaRLwt5eSGRMJGt8CmV0.
This key is not known by any other names

git@192.168.3.252's password:

git@192.168.3.252's password:

git@192.168.3.252's password:
git@192.168.3.252: Permission denied (publickey,password).
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

网上说的配置known_hosts文件，选yes通通不好用

 

经过仔细查看发现新版的加密算法由RSA变成了ED25519

所以他才会询问ED25519 key fingerprint is SHA256:k4ViHJBFryacGI+BqHphyjDBaRLwt5eSGRMJGt8CmV0.

让你确认服务器的ed25519公钥的指纹

而我们一直配置的都是RSA算法，比如名字也叫 id_rsa.pub，id_rsa

本地根本没生成过ed25519的公私钥，所以能通讯才怪

 

在git命令行执行生成ed25519的公私钥

ssh-keygen -t ed25519 -C "xxx@xx.com"

本地会生成id_ed25519.pub和id_ed25519两个文件

把id_ed25519.pub里面的内容配置到后台ssh里面

一切就顺利了
