System.Security.Cryptography.Pkcs.EnvelopedCms.GetCspParams return 异常 "Cannot find object or property."

Question

我在尝试解密文件时遇到异常：

           var encData = File.ReadAllBytes(encFile);

           var file = File.ReadAllBytes(encFile);
        
           ContentInfo cinf = new ContentInfo(file);

           var ec = new EnvelopedCms(cinf);

           X509Store store = new X509Store(StoreName.My, StoreLocation.CurrentUser);
           store.Open(OpenFlags.ReadOnly);

           ec.Decode(encData);

           ec.Decrypt(store.Certificates);

我完全知道 List store.Certificates 中存在适当的证书，为什么会抛出异常？这段代码在我添加那个新证书之前就已经工作了，除了散列算法之外与以前没有区别...

更新：完全调用堆栈异常是

   at System.Security.Cryptography.Pkcs.EnvelopedCms.GetCspParams(RecipientInfo recipientInfo, X509Certificate2Collection extraStore, CMSG_DECRYPT_PARAM& cmsgDecryptParam)
    at System.Security.Cryptography.Pkcs.EnvelopedCms.DecryptContent(RecipientInfoCollection recipientInfos, X509Certificate2Collection extraStore)
    at System.Security.Cryptography.Pkcs.EnvelopedCms.Decrypt(X509Certificate2Collection extraStore)

Answer 1

此异常的原因 - 不支持哈希算法 - 在俄罗斯标准 GOST R 34.11-2012 或 STREEBOG 中定义。所以因为我有 CryptoPro 许可证，所以我使用 cryptcp.exe 和命令行参数 ...
