Class 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");

Method Summary

void
addSigner(PrivateKey key, X509Certificate cert, String digestOID)
add a signer - no attributes other than the default ones will be provided here.
void
addSigner(PrivateKey key, X509Certificate cert, String digestOID, AttributeTable signedAttr, AttributeTable unsignedAttr)
add a signer with extra signed/unsigned attributes.
void
addSigner(PrivateKey key, X509Certificate cert, String digestOID, CMSAttributeTableGenerator signedAttrGen, CMSAttributeTableGenerator unsignedAttrGen)
add a signer with extra signed/unsigned attributes based on generators.
CMSSignedData
generate(String signedContentType, CMSProcessable content, boolean encapsulate, String sigProvider)
generate a signed object that for a CMS Signed Data object using the given provider - if encapsulate is true a copy of the message will be included in the signature.

generate(String signedContentType, CMSProcessable content, boolean encapsulate, String sigProvider, boolean addDefaultAttributes)
Similar method to the other generate methods.

                      String digestOID)
            throws IllegalArgumentException
add a signer - no attributes other than the default ones will be provided here.

                      X509Certificate cert,
                      String digestOID,
                      AttributeTable signedAttr,
                      AttributeTable unsignedAttr)
            throws IllegalArgumentException
add a signer with extra signed/unsigned attributes.

addSigner

public void addSigner(PrivateKey key,
                      X509Certificate cert,
                      String digestOID,
                      CMSAttributeTableGenerator signedAttrGen,
                      CMSAttributeTableGenerator unsignedAttrGen)
            throws IllegalArgumentException
add a signer with extra signed/unsigned attributes based on generators.

generate

public CMSSignedData generate(String signedContentType,
                              CMSProcessable content,
                              boolean encapsulate,
                              String sigProvider)
            throws NoSuchAlgorithmException,
                   NoSuchProviderException,
                   CMSException
generate a signed object that for a CMS Signed Data object using the given provider - if encapsulate is true a copy of the message will be included in the signature. The content type is set according to the OID represented by the string signedContentType.

generate

public CMSSignedData generate(String signedContentType,
                              CMSProcessable content,
                              boolean encapsulate,

                              boolean addDefaultAttributes)
            throws NoSuchAlgorithmException,
                   NoSuchProviderException,
                   CMSException
Similar method to the other generate methods. The additional argument addDefaultAttributes indicates whether or not a default set of signed attributes need to be added automatically. If the argument is set to false, no attributes will get added at all.

generate

public CMSSignedData generate(CMSProcessable content,
                              String sigProvider)
            throws NoSuchAlgorithmException,
                   NoSuchProviderException,
                   CMSException
generate a signed object that for a CMS Signed Data object using the given provider.

generate

public CMSSignedData generate(CMSProcessable content,
                              boolean encapsulate,

            throws NoSuchAlgorithmException,
                   NoSuchProviderException,
                   CMSException
generate a signed object that for a CMS Signed Data object using the given provider - if encapsulate is true a copy of the message will be included in the signature with the default content type "data".
