  public void initialiseMessageImprintDigestCalculator​(DigestCalculator calculator)
                                                throws CMSException

  Initialise the passed in calculator with the MetaData for this message, if it is required as part of the initial message imprint calculation.

  Parameters:

  calculator - the digest calculator to be initialised.

  Throws:

  CMSException - if the MetaData is required and cannot be processed

• getMessageImprintDigestCalculator

  public DigestCalculator getMessageImprintDigestCalculator​(DigestCalculatorProvider calculatorProvider)
                                                     throws OperatorCreationException

  Returns an appropriately initialised digest calculator based on the message imprint algorithm described in the first time stamp in the TemporalData for this message. If the metadata is required to be included in the digest calculation, the returned calculator will be pre-initialised.

  Parameters:

  calculatorProvider - a provider of DigestCalculator objects.

  Returns:

  an initialised digest calculator.

  Throws:

  OperatorCreationException - if the provider is unable to create the calculator.

                       CMSException

  Validate the digests present in the TimeStampTokens contained in the CMSTimeStampedData.

  Parameters:

  calculatorProvider - provider for digest calculators

  dataDigest - the calculated data digest for the message

  Throws:

  ImprintDigestInvalidException - if an imprint digest fails to compare

  CMSException - if an exception occurs processing the message.

  Validate the passed in timestamp token against the tokens and data present in the message.

  Parameters:

  calculatorProvider - provider for digest calculators

  dataDigest - the calculated data digest for the message.

  timeStampToken - the timestamp token of interest.

  Throws:

  ImprintDigestInvalidException - if the token is not present in the message, or an imprint digest fails to compare.
