public class CMSSignedDataGenerator

extends java.lang.Object

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");
 

Field Summary

static java.lang.String	DIGEST_MD5
static java.lang.String	DIGEST_SHA1
static java.lang.String	ENCRYPTION_DSA
static java.lang.String	ENCRYPTION_RSA

Constructor Summary

CMSSignedDataGenerator()
base constructor

Method Summary

void	addCertificatesAndCRLs(java.security.cert.CertStore certStore) add the certificates and CRLs contained in the given CertStore to the pool that will be included in the encoded signature block.
void	addSigner(java.security.PrivateKey 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(java.security.PrivateKey key, java.security.cert.X509Certificate cert, java.lang.String digestOID, AttributeTable signedAttr, AttributeTable unsignedAttr) add a signer with extra signed/unsigned attributes.
CMSSignedData	generate(CMSProcessable content, boolean encapsulate, java.lang.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.
CMSSignedData	generate(CMSProcessable content, java.lang.String sigProvider) generate a signed object that for a CMS Signed Data object using the given provider.
