在Windows上使用Git命令clone项目的时候报错"ERROR: You're using an RSA key with SHA-1, which is no longer allowed."，具体错误如下：

shell 复制代码

$ git clone [email protected]:xxx/xxx.git
Cloning into 'xxx'...
ERROR: You're using an RSA key with SHA-1, which is no longer allowed.
Please use a newer client or a different key type.
Please see https://github.blog/2021-09-01-improving-git-protocol-security-github/ for more information.

fatal: Could not read from remote repository.

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

错误原因是github现在不再支持SHA-1的加密方式了。因此需要将SHA-1的加密方式修改为ECDSA的方式。

执行下面的命令生成ECDSA密钥

shell 复制代码

ssh-keygen -t ecdsa -b 521 -C "[email protected]"

命令执行完成后会在~/.ssh目录中产生两个文件id_ecdsa和id_ecdsa.pub，分别为私钥和公钥。

我们将id_ecdsa.pub文件内容复制到 github -> Settings -> SSH and GPG keys -> New SSH Key

然后运行下面命令验证

shell 复制代码

$ ssh -T [email protected]

Hi kongxx! You've successfully authenticated, but GitHub does not provide shell access.

如果出现上面的提示，说明 ssh key 已经配置成功。
