Constructor Details

CAdESEmbeddedEvidenceRecordHelper

public CAdESEmbeddedEvidenceRecordHelper(CAdESSignature signature)

Constructor for an evidence record applied for the whole signature content (not yet embedded)

Parameters:

signature - CAdESSignature

CAdESEmbeddedEvidenceRecordHelper

public CAdESEmbeddedEvidenceRecordHelper(CAdESSignature signature,
 CAdESAttribute evidenceRecordAttribute)

Default constructor

Parameters:

signature - CAdESSignature

evidenceRecordAttribute - CAdESAttribute

Method Details

setDetachedContents

public void setDetachedContents(List<DSSDocument> detachedContents)

Description copied from class: AbstractEmbeddedEvidenceRecordHelper

Sets a list of documents used for validation of a detached signature

Overrides:

setDetachedContents in class AbstractEmbeddedEvidenceRecordHelper

Parameters:

detachedContents - list of DSSDocuments

getDigestBuilder

protected SignatureEvidenceRecordDigestBuilder getDigestBuilder(AdvancedSignature signature,
 SignatureAttribute evidenceRecordAttribute,
 DigestAlgorithm digestAlgorithm)

Description copied from class: AbstractEmbeddedEvidenceRecordHelper

Gets implementation of the signature digest builder for the given evidence record

Specified by:

getDigestBuilder in class AbstractEmbeddedEvidenceRecordHelper

Parameters:

signature - AdvancedSignature

evidenceRecordAttribute - SignatureAttribute

digestAlgorithm - DigestAlgorithm

Returns:

SignatureEvidenceRecordDigestBuilder

getDetachedDocument

protected DSSDocument getDetachedDocument()

Gets the detached document covered by a detached CAdES

Returns:

DSSDocument

setDEREncoding

protected void setDEREncoding(SignatureEvidenceRecordDigestBuilder digestBuilder,
 boolean derEncoded)

Description copied from class: AbstractEmbeddedEvidenceRecordHelper

Sets the encoding to be used on the hash computation to the SignatureEvidenceRecordDigestBuilder whether applicable

Specified by:

setDEREncoding in class AbstractEmbeddedEvidenceRecordHelper

Parameters:

digestBuilder - SignatureEvidenceRecordDigestBuilder

derEncoded - whether signature shall be DER encoded

isEncodingSelectionSupported

public boolean isEncodingSelectionSupported()

Description copied from interface: EmbeddedEvidenceRecordHelper

Gets whether the selection of a target encoding is supported by the current implementation. This method is used to resolve the interoperability issues between ETSI TS 119 122-3 and RFC 4998 embedded ERS, requiring hash computation in different ways.

Returns:

TRUE if the encoding selection is supported by the current implementation, FALSE otherwise
