我搜索了一种从数字签名的PE文件中检索信息的方法。我需要出版商，出版商链接，发行人名称和主题名称。我需要winapi / c / c ++代码（函数），我需要一个快速的方法，我不需要检查签名是否有效。
答案 0 :(得分：6)
这是我为我的一个项目编写的代码。它返回类型为NSIGINFO的结构中的详细信息。随意使用它 - 没有必要的归属，但如果您保持版权完整，我将不胜感激。
如果缺少任何功能（我必须从几个不同的地方合并，以便我可能遗漏了一些东西），请告诉我，我会进行必要的调整。
让我知道这对你有什么用。祝你好运。

Microsoft提供了一种在此支持链接中执行此操作的方法：How To Get Information from Authenticode Signed Executables
您可以使用WinVerifyTrust（）API验证签名的Authenticode 可执行文件。
虽然签名已经过验证，但程序也可能需要这样做 以下内容：
- 确定签名的证书的详细信息 可执行文件。
- 确定文件时间的日期和时间 冲压而成。
- 检索与该文件关联的网址链接。
- 检索时间戳证书。
本文演示了如何使用 CryptQueryObject（）API从中检索详细信息 Authenticode签署了可执行文件。
