public class CMSSignedDataGenerator
extends CMSSignedGenerator
general class for generating a pkcs7-signature message.

A simple example of usage, generating a detached signature. 

      List             certList = new ArrayList();
      CMSTypedData     msg = new CMSProcessableByteArray("Hello world!".getBytes());

      certList.add(signCert);

      Store           certs = new JcaCertStore(certList);

      CMSSignedDataGenerator gen = new CMSSignedDataGenerator();
      ContentSigner sha1Signer = new JcaContentSignerBuilder("SHA1withRSA").setProvider("BC").build(signKP.getPrivate());

      gen.addSignerInfoGenerator(
                new JcaSignerInfoGeneratorBuilder(
                     new JcaDigestCalculatorProviderBuilder().setProvider("BC").build())
                     .build(sha1Signer, signCert));

      gen.addCertificates(certs);

      CMSSignedData sigData = gen.generate(msg, false);
