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);

Method Detail

generate

public CMSSignedData generate(CMSTypedData content)
                       throws CMSException
Generate a CMS Signed Data object carrying a detached CMS signature.
Parameters:
content - the content to be signed.

generate

public CMSSignedData generate(CMSTypedData content,
                              boolean encapsulate)
                       throws CMSException
Generate a CMS Signed Data object which can be carrying a detached CMS signature, or have encapsulated data, depending on the value of the encapsulated parameter.
Parameters:
content - the content to be signed.
encapsulate - true if the content should be encapsulated in the signature, false otherwise.

generateCounterSigners

public SignerInformationStore generateCounterSigners(SignerInformation signer)

Parameters:
signer - the signer to be countersigned
Returns:
a store containing the signers.
