Constructor	Description
ASN1EvidenceRecordRenewalDigestBuilder(ASN1EvidenceRecord asn1EvidenceRecord)	Creates an instance of ASN1EvidenceRecordRenewalDigestBuilder allowing to build hash for ASN1EvidenceRecord's renewal, with a default SHA256 digest algorithm to be used on hash-tree renewal computation (see note).
ASN1EvidenceRecordRenewalDigestBuilder(ASN1EvidenceRecord asn1EvidenceRecord, DigestAlgorithm digestAlgorithm)	Creates an instance of XMLEvidenceRecordRenewalDigestBuilder allowing to build hash for XmlEvidenceRecord's renewal, with the provided digestAlgorithm (see note below).
ASN1EvidenceRecordRenewalDigestBuilder(DSSDocument document)	Creates an instance of ASN1EvidenceRecordRenewalDigestBuilder allowing to build hash for ASN.1 evidence record document's renewal.
ASN1EvidenceRecordRenewalDigestBuilder(DSSDocument document, DigestAlgorithm digestAlgorithm)	Creates an instance of ASN1EvidenceRecordRenewalDigestBuilder allowing to build hash for ASN.1 evidence record document's renewal, with the provided digestAlgorithm (see note below).

Constructor Details

ASN1EvidenceRecordRenewalDigestBuilder

public ASN1EvidenceRecordRenewalDigestBuilder(DSSDocument document)

Creates an instance of ASN1EvidenceRecordRenewalDigestBuilder allowing to build hash for ASN.1 evidence record document's renewal. Builds digest for the last available ArchiveTimeStamp or ArchiveTimeStampChain, based on the called method.

Parameters:

document - DSSDocument

ASN1EvidenceRecordRenewalDigestBuilder

public ASN1EvidenceRecordRenewalDigestBuilder(DSSDocument document,
 DigestAlgorithm digestAlgorithm)

Creates an instance of ASN1EvidenceRecordRenewalDigestBuilder allowing to build hash for ASN.1 evidence record document's renewal, with the provided digestAlgorithm (see note below). Builds digest for the last available ArchiveTimeStamp or ArchiveTimeStampChain, based on the called method. NOTE: time-stamp renewal uses digest algorithm extracted from the last ArchiveTimeStampChain.

Parameters:

document - DSSDocument

digestAlgorithm - DigestAlgorithm to be used on hash-tree renewal hash computation

ASN1EvidenceRecordRenewalDigestBuilder

public ASN1EvidenceRecordRenewalDigestBuilder(ASN1EvidenceRecord asn1EvidenceRecord)

Creates an instance of ASN1EvidenceRecordRenewalDigestBuilder allowing to build hash for ASN1EvidenceRecord's renewal, with a default SHA256 digest algorithm to be used on hash-tree renewal computation (see note). Builds digest for the last available ArchiveTimeStamp or ArchiveTimeStampChain, based on the called method. NOTE: time-stamp renewal uses digest algorithm extracted from the last ArchiveTimeStampChain.

Parameters:

asn1EvidenceRecord - ASN1EvidenceRecord

ASN1EvidenceRecordRenewalDigestBuilder

public ASN1EvidenceRecordRenewalDigestBuilder(ASN1EvidenceRecord asn1EvidenceRecord,
 DigestAlgorithm digestAlgorithm)

Creates an instance of XMLEvidenceRecordRenewalDigestBuilder allowing to build hash for XmlEvidenceRecord's renewal, with the provided digestAlgorithm (see note below). Builds digest for the last available ArchiveTimeStamp or ArchiveTimeStampChain, based on the called method. NOTE: time-stamp renewal uses digest algorithm extracted from the last ArchiveTimeStampChain.

Parameters:

asn1EvidenceRecord - ASN1EvidenceRecord

digestAlgorithm - DigestAlgorithm to be used on hash-tree renewal hash computation

Method Details
