This interface DocumentSignatureService provides operations for the signature creation and for its extension.

Method Summary

Modifier and Type	Method	Description
DSSDocument	extendDocument(DSSDocument toExtendDocument, SP parameters)	Extends the level of the signatures in the toExtendDocument
TimestampToken	getContentTimestamp(DSSDocument toSignDocument, SP parameters)	This method allows to compute a content-timestamp (which is added in the signed properties)
ToBeSigned	getDataToSign(DSSDocument toSignDocument, SP parameters)	Retrieves the bytes of the data that need to be signed based on the toSignDocument and parameters .
void	setTspSource(TSPSource tspSource)	This setter allows to define the TSP (timestamp provider) source.
DSSDocument	signDocument(DSSDocument toSignDocument, SP parameters, SignatureValue signatureValue)	Signs the toSignDocument with the provided signatureValue.
DSSDocument	timestamp(DSSDocument toTimestampDocument, TP parameters)	This method allows to add a timestamp to an unsigned document

Method Details

getDataToSign

ToBeSigned getDataToSign(DSSDocument toSignDocument, SP parameters)

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

signDocument

DSSDocument signDocument(DSSDocument toSignDocument, SP parameters, SignatureValue signatureValue)

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)

extendDocument

DSSDocument extendDocument(DSSDocument toExtendDocument, SP parameters)

Extends the level of the signatures in the toExtendDocument

Parameters:

toExtendDocument - document to extend

parameters - set of the driving signing parameters

Returns:

the extended signature

setTspSource

void setTspSource(TSPSource tspSource)

This setter allows to define the TSP (timestamp provider) source.

Parameters:

tspSource - The time stamp source which is used when timestamping the signature.

getContentTimestamp

TimestampToken getContentTimestamp(DSSDocument toSignDocument, SP parameters)

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:

a timestamp token

timestamp

DSSDocument timestamp(DSSDocument toTimestampDocument, TP parameters)

This method allows to add a timestamp to an unsigned document

Parameters:

toTimestampDocument - the document to be timestamped

parameters - set of the driving timestamping parameters

Returns:

the timestamped document
