从SHA1到SHA256的数字标牌 [英] Digital sign From SHA1 to SHA256

问题描述

您好，我正在尝试更新执行数字签名的功能，我想从SHA1切换到SHA256，这是当前功能:

Hello, I'm trying to update a function that performs a digital signature, I want to switch from SHA1 to SHA256 this is the current function:

private byte[] zSignData(Byte[] msg, X509Certificate2 signerCert)
{
 ContentInfo contentInfo = new ContentInfo(msg);
 SignedCms signedCms = new SignedCms(contentInfo, false);
 CmsSigner cmsSigner = new CmsSigner(signerCert);

 cmsSigner.DigestAlgorithm = new Oid("1.3.14.3.2.26"); //SHA1

 signedCms.ComputeSignature(cmsSigner, false);

 return signedCms.Encode();
}

此功能运行良好

要更改为SHA256，我更改了

To update to SHA256, I changed

cmsSigner.DigestAlgorithm =新的Oid("1.3.14.3.2.26"); //SHA1

cmsSigner.DigestAlgorithm = new Oid("1.3.14.3.2.26"); //SHA1

使用

cmsSigner.DigestAlgorithm =新的Oid("2.16.840.1.101.3.4.2.1");//SHA256

cmsSigner.DigestAlgorithm = new Oid("2.16.840.1.101.3.4.2.1");//SHA256

但在

signedCms.ComputeSignature(cmsSigner，false);

signedCms.ComputeSignature(cmsSigner, false);

我收到以下异常System.Security.Cryptography.CryptographicException Message =存在内部错误.

I get the following exception System.Security.Cryptography.CryptographicException Message=There was an internal error.

(InnerException为null，eventviewer中没有消息)

(InnerException is null and no message in eventviewer)

有人有建议吗?

我使用VS2010 Professional 64和Win7 Professional 64以及我安装了智能卡随附的加密服务提供商CSP.

I work with VS2010 Professional 64 and win7 professional 64 and  I installed the crypto service provider CSP provided with the smart card.

非常感谢
