Constructor Detail

PAdESService

public PAdESService(CertificateVerifier certificateVerifier)

This is the constructor to create an instance of the PAdESService. 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 Detail

getContentTimestamp

public TimestampToken getContentTimestamp(DSSDocument toSignDocument,
                                          PAdESSignatureParameters parameters)

Description copied from interface: DocumentSignatureService

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

Parameters:

toSignDocument - document to sign or the already existing signature

parameters - set of the driving signing parameters

Returns:

getDataToSign

public ToBeSigned getDataToSign(DSSDocument toSignDocument,
                                PAdESSignatureParameters parameters)
                         throws DSSException

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

Parameters:

toSignDocument - document to sign or the already existing signature

parameters - set of the driving signing parameters

Returns:

the data to be signed

Throws:

DSSException - if an error occurred

computeDocumentDigest

protected byte[] computeDocumentDigest(DSSDocument toSignDocument,
                                       PAdESSignatureParameters parameters)

signDocument

public DSSDocument signDocument(DSSDocument toSignDocument,
                                PAdESSignatureParameters parameters,
                                SignatureValue signatureValue)
                         throws DSSException

Description copied from interface: DocumentSignatureService

Signs the toSignDocument with the provided signatureValue.

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)

Throws:

DSSException - if an error occurred

generateCMSSignedData

protected byte[] generateCMSSignedData(DSSDocument toSignDocument,
                                       PAdESSignatureParameters parameters,
                                       SignatureValue signatureValue)

extendDocument

public DSSDocument extendDocument(DSSDocument original,
                                  PAdESSignatureParameters parameters)
                           throws DSSException

Description copied from interface: DocumentSignatureService

Extends the level of the signatures in the toExtendDocument

Parameters:

original - document to extend

parameters - set of the driving signing parameters

Returns:

the extended signature

Throws:

DSSException - if an error occurred

getAvailableSignatureFields

public List<String> getAvailableSignatureFields(DSSDocument document)

This method returns not signed signature-fields

Parameters:

document - the pdf document

Returns:

the list of empty signature fields

addNewSignatureField

public DSSDocument addNewSignatureField(DSSDocument document,
                                        SignatureFieldParameters parameters)

This method allows to add a new signature field to an existing pdf document

Parameters:

document - the pdf document

parameters - the parameters with the coordinates,... of the signature field

Returns:

the pdf document with the new added signature field
