我有一个用 c# 和 Microsoft 的 EncryptedXml 例程加密的 xml 文件。来源是 SamlTool.com 示例响应。下面列出了加密版本，以及公钥和私钥。SamlTool 响应验证器（此处）只是说“解密数据失败”。我可以手动提取加密 xml 的各个部分并使用 c# 库正确解密它（但不是 EncryptedXml，因为它需要证书位于存储而不是文件中）。

我究竟做错了什么？我假设这是一个语法问题，但 SamlTool 模式验证器说没问题。我的下一个想法是在 xml 数据中没有设置一些默认值，这在 SamlTool 和 microsoft 之间是不同的，但我不知道它是什么。

加密的 XML
