【问题描述】：

我已经使用 PuTTY 生成了这对密钥，将公共密钥放在 github 上。然后我从 Git Extensions 运行身份验证代理，添加密钥，单击“关闭”按钮，尝试连接到 GitHub，但收到拒绝访问的消息：

WL_Temp@proj ~/Projects/Squeaky (feature/STRINGERV2-182)
$ ssh -T git@github.com
Permission denied (publickey).

WL_Temp@proj ~/Projects/Squeaky (feature/STRINGERV2-182)
$ ssh -aT git@github.com

在那之后，我似乎尝试了一切可能会有所帮助但失败的方法。能解决吗？

标签： git ssh putty

【解决方案1】：

ssh-add -l 验证 ssh 是否可以访问您的代理（它没有权限，因为您没有看到提供这样的密钥）。

openssh 也不适用于 PuTTY 密钥和代理。您需要将密钥从 PuTTY 格式转换为 openssh 格式，以便在终端 ssh 中使用它们。

【解决方案2】：

Git for Windows 附带一个 Windows 版本的 OpenSSH 客户端，默认使用。

它能够与 PuTTY 一起工作 - 这是通过正确设置 GIT_SSH 环境变量来完成的（并在 PuTTY 上进行一点操作以使其信任您连接到的服务器）。

这些事情在this guide中解释得很好。
