public DSSMessageDigest buildTimeStampRenewalDigest(ArchiveTimeStampObject archiveTimeStamp)

Description copied from class: AbstractEvidenceRecordRenewalDigestBuilderHelper

This method builds digest for a time-stamp renewal using a digest algorithm from the

Specified by:

buildTimeStampRenewalDigest in class AbstractEvidenceRecordRenewalDigestBuilderHelper

Parameters:

archiveTimeStamp - ArchiveTimeStampObject to build digest on

Returns:

Digest

buildTimeStampRenewalDigest

public DSSMessageDigest buildTimeStampRenewalDigest(ArchiveTimeStampObject archiveTimeStamp,
 DigestAlgorithm digestAlgorithm)

This method builds digest for a time-stamp renewal with the specified digestAlgorithm

Parameters:

archiveTimeStamp - ArchiveTimeStampObject to build digest on

digestAlgorithm - DigestAlgorithm to be used on digest computation

Returns:

Digest

buildArchiveTimeStampSequenceDigest

public DSSMessageDigest buildArchiveTimeStampSequenceDigest(ArchiveTimeStampChainObject archiveTimeStampChain)

Description copied from class: AbstractEvidenceRecordRenewalDigestBuilderHelper

Builds digest for renewal of the hash-tree, considering the provided archiveTimeStampChainObject as the last chain in the evidence record. Note: this method build digest solely for ArchiveTimeStampChainObject without considering detached content. Please use #buildHashTreeRenewalDigestGroup method instead fo hash calculation in case of a hash-tree renewal with a new time-stamp

Specified by:

buildArchiveTimeStampSequenceDigest in class AbstractEvidenceRecordRenewalDigestBuilderHelper

Parameters:

archiveTimeStampChain - ArchiveTimeStampChainObject

Returns:

DSSMessageDigest

buildArchiveTimeStampSequenceDigest

public DSSMessageDigest buildArchiveTimeStampSequenceDigest(DigestAlgorithm digestAlgorithm,
 int archiveTimeStampChainOrder)

This method builds digest for a time-stamp chain renewal with the specified digestAlgorithm

Parameters:

digestAlgorithm - DigestAlgorithm to be used for digest calculation

archiveTimeStampChainOrder - order value of the last archive time-stamp chain to be concatenated for digest computation

Returns:

DSSMessageDigest

computeChainAndDocumentHash

public DSSMessageDigest computeChainAndDocumentHash(Digest archiveTimeStampChainHash,
 DSSDocument document)

Computes a hash value for chain-hash and document-hash

Parameters:

archiveTimeStampChainHash - Digest hash of the previous ArchiveTimeStampChain

document - DSSDocument detached document

Returns:

DSSMessageDigest
