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

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:

document - DSSDocument containing a CAdES Signature to add a SignaturePolicyStore to

signaturePolicyStore - SignaturePolicyStore to add

Returns:

DSSDocument CAdESSignature with an incorporated SignaturePolicyStore

getDataToBeCounterSigned

public ToBeSigned getDataToBeCounterSigned(DSSDocument signatureDocument,
 CAdESCounterSignatureParameters parameters)

Description copied from interface: CounterSignatureService

Retrieves the bytes of the data that need to be counter signed from signatureDocument. signatureDocument shall be a valid signature of the same type

Specified by:

getDataToBeCounterSigned in interface CounterSignatureService<CAdESCounterSignatureParameters>

Parameters:

signatureDocument - DSSDocument representing the original signature to be counter signed

parameters - set of the driving signing parameters for a counter signature

Returns:

ToBeSigned to be counter signed byte array (signature value retrieved from the signatureDocument)

getDataToBeCounterSigned

public ToBeSigned getDataToBeCounterSigned(DSSDocument signatureDocument,
 org.bouncycastle.cms.SignerInformation signerInfoToCounterSign,
 CAdESSignatureParameters parameters)

Returns a data toBeSigned for a counter signature on the given signerInfoToCounterSign

Parameters:

signatureDocument - DSSDocument containing a signature to be counter signed

signerInfoToCounterSign - SignerInformation to counter sign

parameters - CAdESSignatureParameters

Returns:

ToBeSigned

counterSignSignature

public DSSDocument counterSignSignature(DSSDocument signatureDocument,
 CAdESCounterSignatureParameters parameters,
 SignatureValue signatureValue)

Description copied from interface: CounterSignatureService

Counter signs the signatureDocument with the provided signatureValue.

Specified by:

counterSignSignature in interface CounterSignatureService<CAdESCounterSignatureParameters>

Parameters:

signatureDocument - DSSDocument to be counter signed

parameters - set of the driving signing parameters for a counter signature
