      extended byorg.bouncycastle.cms.CMSSignedDataGenerator

public class CMSSignedDataGenerator
extends CMSSignedGenerator

general class for generating a pkcs7-signature message.

A simple example of usage.

      CertStore               certs...
      CMSSignedDataGenerator    gen = new CMSSignedDataGenerator();

      gen.addSigner(privKey, cert, CMSSignedGenerator.DIGEST_SHA1);
      gen.addCertificatesAndCRLs(certs);

      CMSSignedData           data = gen.generate(content, "BC");
