Git 克隆。 key_load_public : invalid format Permission denied (publickey)

Question

我在 Windows 10 上使用 puttygen.exe 生成私钥和公钥。我将这些 key 保存在 C:\Users\Alexander\.ssh\

公钥已添加到远程仓库(不是我做的。我没有访问权限)。

然后我在 Git Bash 中使用命令:

git clone git@ipaddress:project_name.git

我得到一个错误:

key_load_public: invalid format
Permission denied (publickey).
fatal: Could not read from remote repository.

示例键(仅为示例而生成)

id_rsa.ppk

这里可能出了什么问题？

Answer 1

Git 使用 OpenSSH，它不支持 PuTTY key 格式。您需要将其转换为 OpenSSH 格式。这在 SO 文档中进行了描述，现在在对 Not able to add SSH key in Jenkins configuration 的回答中进行了描述。 :

• 打开 PuttyGen
• 点击加载
• 加载您的私钥
• 转到Conversions->Export OpenSSH 并导出您的私钥
• 将您的私钥复制到~/.ssh/id_rsa
