Class CMSSignedDataGenerator

java.lang.Object
  kz.gamma.hardware.cms.CMSSignedGenerator
      kz.gamma.hardware.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, GammaTechProvider.PROVIDER_NAME);

Method Summary

void	addSigner(JCEPrivateKey key, java.security.cert.X509Certificate cert, java.lang.String digestOID) add a signer - no attributes other than the default ones will be provided here.
void	addSigner(JCEPrivateKey key, java.security.cert.X509Certificate cert, java.lang.String digestOID, AttributeTable signedAttr, AttributeTable unsignedAttr) add a signer with extra signed/unsigned attributes.
void	addSigner(JCEPrivateKey key, java.security.cert.X509Certificate cert, java.lang.String digestOID, CMSAttributeTableGenerator signedAttrGen, CMSAttributeTableGenerator unsignedAttrGen) add a signer with extra signed/unsigned attributes based on generators.
CMSSignedData	generate(CMSProcessable content, boolean encapsulate, JCESignature signature) 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".
CMSSignedData	generate(CMSProcessable content, JCESignature signature) generate a signed object that for a CMS Signed Data object using the given provider.
CMSSignedData	generate(java.lang.String signedContentType, CMSProcessable content, boolean encapsulate, JCESignature signature) 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.
CMSSignedData	generate(java.lang.String signedContentType, CMSProcessable content, boolean encapsulate, JCESignature signature, boolean addDefaultAttributes) Similar method to the other generate methods.

generate

public CMSSignedData generate(CMSProcessable content,
                              JCESignature signature)
                       throws CMSException

generate a signed object that for a CMS Signed Data object using the given provider.

Throws:

CMSException

generate

public CMSSignedData generate(java.lang.String signedContentType,
                              CMSProcessable content,
                              boolean encapsulate,
                              JCESignature signature)
                       throws 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.

Throws:

CMSException

generate

public CMSSignedData generate(java.lang.String signedContentType,
                              CMSProcessable content,
                              boolean encapsulate,

                       throws 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.

Throws:

CMSException

                       throws 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".

Throws:

CMSException
