SignedCms.ComputeSignature [英] SignedCms.ComputeSignature

问题描述

你好，

我写了一个小程序来签名和加密文件。在x86上一切正常，但在x64上我得到了

System.Security.Cryptography.CryptographicException：找不到证书和解密私钥。

在System.Security.Cryptography。 Pkcs.PkcsUtils.CreateSignerEncodeInfo（CmsSigner签名者，布尔静默）
System.Security.Cryptography.Pkcs.SignedCms.Sign（CmsSigner签名者，布尔静默）
System.Security.Cryptography.Pkcs.SignedCms.ComputeSignature（ CmsSigner signer，Boolean silent）


关键代码是





























-family：Courier New; font-size：11px">

1	ContentInfo content = new ContentInfo（数据）;
2	SignedCms signedMessage = new SignedCms（content）;
3	CmsSigner signer = new CmsSigner（signingCert）;
4	signedMessage .ComputeSignature（签名者）;
5	byte [] signedBytes = signedMessage.Encode（）;

解决方案

CreateSignerEncodeInfo（）是一个P / Invokes的.NET方法本机CryptoAPI功能可以完成工作。您获得的异常表明64位Windows本机加密支持功能有问题。究竟是什么问题很难找到。我不羡慕你的问题。

Hello,

i've written a small program to sign and encrypt files. On x86 everything works fine, but on x64 I get

System.Security.Cryptography.CryptographicException: The certificate and the private key for decryption were not found.

   at System.Security.Cryptography.Pkcs.PkcsUtils.CreateSignerEncodeInfo(CmsSigner signer, Boolean silent)
   at System.Security.Cryptography.Pkcs.SignedCms.Sign(CmsSigner signer, Boolean silent)
   at System.Security.Cryptography.Pkcs.SignedCms.ComputeSignature(CmsSigner signer, Boolean silent)


The critical code is

1	ContentInfo content = new ContentInfo(data);
2	SignedCms signedMessage = new SignedCms(content);
3	CmsSigner signer = new CmsSigner(signingCert);
4	signedMessage.ComputeSignature(signer);
5	byte[] signedBytes = signedMessage.Encode();

解决方案

CreateSignerEncodeInfo() is a .NET method that P/Invokes to the native CryptoAPI functions to get the job done.  The exception you are getting is indicating that there's something wrong with the 64-bit Windows native cryptography support functions.  What exactly is wrong is going to be hard to find out.  I don't envy your problem.
