c# – 签署并创建一个asn1 signedmessage – Bouncycastle

有没有关于如何签名文件的好教程,并使用bouncycastle将其包装在asn1 pkcs7包中？

解决方法:

过了一段时间,我在bouncyCastle应用程序中的示例中找到了它的完成方式.

实际上,它比我在IText中找到的更简单直接(没有取出框架本身的亲切性).

代码类似于：

        AsymmetricCipherKeyPair signaturePair;
        X509Certificate signatureCert;

        IList certList = new ArrayList();
        IList crlList = new ArrayList();
        CmsProcessable msg = new CmsProcessableByteArray(Encoding.ASCII.GetBytes("I hate hello world!"));

        certList.Add(signatureCert);
        certList.Add(OrigCert);

        crlList.Add(SignCrl);

        IX509Store x509Certs = X509StoreFactory.Create(
            "Certificate/Collection",
            new X509CollectionStoreParameters(certList));
        IX509Store x509Crls = X509StoreFactory.Create(
            "CRL/Collection",
            new X509CollectionStoreParameters(crlList));

        CmsSignedDataGenerator gen = new CmsSignedDataGenerator();

        gen.AddSigner(signaturePair.Private, signatureCert, CmsSignedDataGenerator.DigestSha1);

        gen.AddCertificates(x509Certs);
        gen.AddCrls(x509Crls);

        CmsSignedData signedData = gen.Generate(msg, true);

        //saving in BER encoding
        Stream stream = new MemoryStream(signedData.GetEncoded());
