                         throws CMSException
Method Detail

calculateNextHash

public byte[] calculateNextHash(DigestCalculator calculator)
                         throws CMSException

getContent

public java.io.InputStream getContent()

getDataUri

public java.net.URL getDataUri()
                        throws java.net.MalformedURLException

initialiseMessageImprintDigestCalculator

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.

getFileName

public java.lang.String getFileName()

getMediaType

public java.lang.String getMediaType()

getOtherMetaData

public org.bouncycastle.asn1.cms.AttributeTable getOtherMetaData()

getTimeStampTokens

public TimeStampToken[] getTimeStampTokens()
                                    throws CMSException

validate

public void validate(DigestCalculatorProvider calculatorProvider,
                     byte[] dataDigest)
              throws ImprintDigestInvalidException,
                     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

public void validate(DigestCalculatorProvider calculatorProvider,
                     byte[] dataDigest,
                     TimeStampToken timeStampToken)
              throws ImprintDigestInvalidException,
                     CMSException
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.
CMSException - if an exception occurs processing the message.
