Field Details

resourcesHandlerBuilder

protected DSSResourcesHandlerBuilder resourcesHandlerBuilder

This object is used to create data container objects such as an OutputStream or a DSSDocument

Constructor Details

CAdESService

public CAdESService(CertificateVerifier certificateVerifier)

This is the constructor to create an instance of the CAdESService. A certificate verifier must be provided.

Parameters:

certificateVerifier - CertificateVerifier provides information on the sources to be used in the validation process in the context of a signature.

Method Details

setResourcesHandlerBuilder

public void setResourcesHandlerBuilder(DSSResourcesHandlerBuilder resourcesHandlerBuilder)

This method sets a DSSResourcesHandlerBuilder to be used for operating with internal objects during the signature creation procedure. NOTE: The DSSResourcesHandlerBuilder is supported only within the 'dss-cms-stream' module!

Parameters:

resourcesHandlerBuilder - DSSResourcesHandlerBuilder

getContentTimestamp

public TimestampToken getContentTimestamp(DSSDocument toSignDocument,
 CAdESSignatureParameters parameters)

Description copied from interface: DocumentSignatureService

This method allows to compute a content-timestamp (which is added in the signed properties)

Specified by:

getContentTimestamp in interface DocumentSignatureService<CAdESSignatureParameters,CAdESTimestampParameters>

Parameters:

toSignDocument - document to sign or the already existing signature

parameters - set of the driving signing parameters

Returns:

a timestamp token

getDataToSign

public ToBeSigned getDataToSign(DSSDocument toSignDocument,
 CAdESSignatureParameters parameters)

Description copied from interface: DocumentSignatureService

Retrieves the bytes of the data that need to be signed based on the toSignDocument and parameters. When toSignDocument contains an already existing signature the returned bytes are related to a new parallel signature. - Enveloped signature (XML): a new signature is added and the signed data corresponds to that pointed by the first signature; - Enveloping signature: - - XML: The parallel signature is not possible - - CMS: A new parallel signature is added - Detached signature: - - XML: The parallel signature is added - - CMS: A new parallel signature is added

Specified by:

getDataToSign in interface DocumentSignatureService<CAdESSignatureParameters,CAdESTimestampParameters>

Parameters:

toSignDocument - document to sign or the already existing signature

parameters - set of the driving signing parameters

Returns:

the data to be signed

signDocument

public DSSDocument signDocument(DSSDocument toSignDocument,
 CAdESSignatureParameters parameters,
 SignatureValue signatureValue)

Description copied from interface: DocumentSignatureService

Signs the toSignDocument with the provided signatureValue.

Specified by:

signDocument in interface DocumentSignatureService<CAdESSignatureParameters,CAdESTimestampParameters>

Parameters:

toSignDocument - document to sign

parameters - set of the driving signing parameters

signatureValue - the signature value to incorporate

Returns:

the signed document (toSignDocument with the incorporated signature or the detached signature)

extendDocument

public DSSDocument extendDocument(DSSDocument toExtendDocument,
 CAdESSignatureParameters parameters)

Description copied from interface: DocumentSignatureService

Extends the level of the signatures in the toExtendDocument

Specified by:

extendDocument in interface DocumentSignatureService<CAdESSignatureParameters,CAdESTimestampParameters>

Parameters:

toExtendDocument - document to extend

parameters - set of the driving signing parameters

Returns:

the extended signature

addSignaturePolicyStore

public DSSDocument addSignaturePolicyStore(DSSDocument document,
 SignaturePolicyStore signaturePolicyStore)

Incorporates a Signature Policy Store as an unsigned property into the CAdES Signature

Parameters:

signaturePolicyStore - SignaturePolicyStore to add

Returns:

DSSDocument CAdESSignature with an incorporated SignaturePolicyStore

getCAdESSignaturePolicyStoreBuilder

protected CAdESSignaturePolicyStoreBuilder getCAdESSignaturePolicyStoreBuilder()
