我有以下代码但是当我运行代码时收到错误 System.Security.Cryptography.CryptographicException:找不到原始签名者。, 为什么会这样?是因为我的证书设置不正确吗?
public byte[] GetSignature(string message, X509Certificate2 signingCertificate,
X509Certificate2 encryptionCertificate)
{
byte[] messageBytes = Encoding.ASCII.GetBytes(message);
SignedCms signedCms = new SignedCms(new ContentInfo(messageBytes), true);
CmsSigner cmsSigner = new CmsSigner(SubjectIdentifierType.IssuerAndSerialNumber, signingCertificate);
cmsSigner.IncludeOption = X509IncludeOption.WholeChain;
if (encryptionCertificate != null)
{
cmsSigner.Certificates.Add(encryptionCertificate);
}
Pkcs9SigningTime signingTime = new Pkcs9SigningTime();
cmsSigner.SignedAttributes.Add(signingTime);
signedCms.ComputeSignature(cmsSigner, false);
return signedCms.Encode();
}
答案 0 :(得分:0)
您是否尝试删除此行:
cmsSigner.IncludeOption = X509IncludeOption.WholeChain;
我遇到了与你描述的问题相同的问题,我也使用了WholeChain
选项,省略了它解决了我的问题。我希望它会帮助其他人,即使这个问题是在8个月前发布的。
