Constructor Details

XAdESTimestampMessageDigestBuilder

public XAdESTimestampMessageDigestBuilder(XAdESSignature signature,
 DigestAlgorithm digestAlgorithm)

Default constructor to be used for a new timestamp creation. This constructor requires certain properties to be provided for message-digest computation (see available setters).

Parameters:

signature - XAdESSignature containing timestamps to calculate message-imprint digest for

digestAlgorithm - DigestAlgorithm to be used for message-imprint digest computation

XAdESTimestampMessageDigestBuilder

public XAdESTimestampMessageDigestBuilder(XAdESSignature signature,
 TimestampToken timestampToken)

Constructor to be used for existing timestamp message-imprint computation.

Parameters:

signature - XAdESSignature signature associated with the timestamp

timestampToken - TimestampToken to compute message-digest for

Method Details

setCanonicalizationAlgorithm

public XAdESTimestampMessageDigestBuilder setCanonicalizationAlgorithm(String canonicalizationAlgorithm)

Sets the canonicalization algorithm to be used for message-digest computation

Parameters:

canonicalizationAlgorithm - String

Returns:

this XAdESTimestampMessageDigestBuilder

setEn319132

public XAdESTimestampMessageDigestBuilder setEn319132(boolean en319132)

Sets whether the message-digest should be computed for a EN 319 132-1 standard timestamp token

Parameters:

en319132 - whether the timestamp is of EN 319 132-1 format

Returns:

this XAdESTimestampMessageDigestBuilder

setTimestampAttribute

public XAdESTimestampMessageDigestBuilder setTimestampAttribute(XAdESAttribute timestampAttribute)

Sets a signature attribute corresponding to the time-stamp token. Defined also en319132 based on the provided timestamp attribute.

Parameters:

timestampAttribute - XAdESAttribute

Returns:

this XAdESTimestampMessageDigestBuilder

getContentTimestampMessageDigest

public DSSMessageDigest getContentTimestampMessageDigest()

Description copied from interface: TimestampMessageDigestBuilder

Returns the content timestamp message-imprint digest (timestamped or to be).

Specified by:

getContentTimestampMessageDigest in interface TimestampMessageDigestBuilder

Returns:

DSSMessageDigest representing the message digest on canonicalized data to be timestamped

getAllDataObjectsTimestampMessageDigest

protected DSSMessageDigest getAllDataObjectsTimestampMessageDigest()

Returns the computed message-imprint digest for xades132:AllDataObjectsTimestamp token

Returns:

DSSMessageDigest message-imprint digest

getIndividualDataObjectsTimestampMessageDigest

protected DSSMessageDigest getIndividualDataObjectsTimestampMessageDigest()

Returns the computed message-imprint digest for xades132:IndividualDataObjectsTimestamp token

Returns:

DSSMessageDigest message-imprint digest

getSignatureTimestampMessageDigest

public DSSMessageDigest getSignatureTimestampMessageDigest()

Description copied from interface: TimestampMessageDigestBuilder

Returns the message-imprint digest on data (signature value) that was timestamped by the SignatureTimeStamp for the given timestamp.

Specified by:

getSignatureTimestampMessageDigest in interface TimestampMessageDigestBuilder

Returns:

DSSMessageDigest representing the message-digest on canonicalized data to be timestamped

getTimestampX1MessageDigest

public DSSMessageDigest getTimestampX1MessageDigest()

Description copied from interface: TimestampMessageDigestBuilder

Returns the message-imprint digest to be time-stamped. The data used to create digest contains the digital signature (XAdES example: ds:SignatureValue element), the signature time-stamp(s) present in the AdES-T form, the certification path references and the revocation status references.

Specified by:

getTimestampX1MessageDigest in interface TimestampMessageDigestBuilder

Returns:

DSSMessageDigest representing the message digest on canonicalized data to be timestamped

getTimestampX2MessageDigest

public DSSMessageDigest getTimestampX2MessageDigest()

Description copied from interface: TimestampMessageDigestBuilder

Specified by:

getTimestampX2MessageDigest in interface TimestampMessageDigestBuilder

Returns:

DSSMessageDigest representing the message digest on canonicalized data to be timestamped

getArchiveTimestampMessageDigest

public DSSMessageDigest getArchiveTimestampMessageDigest()

Description copied from interface: TimestampMessageDigestBuilder

Archive timestamp seals the data of the signature in a specific order. We need to retrieve the data for each timestamp.

Specified by:

getArchiveTimestampMessageDigest in interface TimestampMessageDigestBuilder

Returns:

DSSMessageDigest representing the message digest on canonicalized data to be timestamped
