Class DataToSign

java.lang.Object

org.digidoc4j.DataToSign

All Implemented Interfaces:

Serializable

public class DataToSign
extends Object
implements Serializable

Data to be signed externally (e.g. in the Web by a browser plugin).

getDataToSign() and getDigestAlgorithm() can be used to get the data bytes to be signed (this is usually data derived from signature parameters - SignedInfo) and digest algorithm (e.g. SHA-256, SHA-512 etc) used in signing.

After a signature has been created externally, then it must be included back by calling finalize(byte[]) with the signature value. This will return a Signature object with the signature value, OCSP response etc included.

Constructor Detail

DataToSign

public DataToSign(byte[] data,
          SignatureParameters signatureParameters,
          org.digidoc4j.impl.SignatureFinalizer signatureFinalizer)

Constructor

Parameters:

data - Digest value of the data

signatureParameters - Signature parameters

signatureFinalizer - Signature finalizer

Method Detail

getSignatureParameters

public SignatureParameters getSignatureParameters()

Signature parameters used to create the signature.

Returns:

signature parameters.

getDigestAlgorithm

public DigestAlgorithm getDigestAlgorithm()

Signature digest algorithm to be used when creating the signature value.

Returns:

signature digest algorithm.

getDataToSign

public byte[] getDataToSign()

Data to be signed externally.

Returns:

data bytes to be signed.

finalize

public Signature finalize(byte[] signatureValue)

Finalize the signature by adding externally created signature value in bytes. This will get OCSP verification etc. to finalize the signature.

Parameters:

signatureValue - externally created signature value bytes.

Returns:

Finalized signature.
