getTimeStampToken

public TimeStampToken getTimeStampToken()

getSigningCertificate

public X509CertificateHolder getSigningCertificate()

Return the TimeStamp signing certificate if it is present.

Returns:

the TimeStamp signing certificate.

validate

public void validate(SignerInformationVerifier verifier)
              throws TSPException

Validate the time stamp associated with this ArchiveTimeStamp.

Parameters:

verifier - signer verifier for the contained time stamp.

Throws:

TSPException - in case of validation failure or error.

getGenTime

Return the generation time of the time-stamp associated with this archive time stamp.

Returns:

the time the associated time-stamp was created.

getExpiryTime

public java.util.Date getExpiryTime()

Return the not-after date for the time-stamp's signing certificate if it is present.

Returns:

the issuing TSP server not-after date, or null if not present.

toASN1Structure

public org.bouncycastle.asn1.tsp.ArchiveTimeStamp toASN1Structure()

getEncoded

public byte[] getEncoded()
                  throws java.io.IOException

fromTimeStampToken

public static ERSArchiveTimeStamp fromTimeStampToken(TimeStampToken tspToken,
                                                     DigestCalculatorProvider digCalcProv)

Build an ArchiveTimeStamp from a regular time stamp token.

Parameters:

tspToken - the TimeStampToken in the regular time stamp.

digCalcProv - a digest calculator provider for use with the time stamp.

Returns:

an ERSArchiveTimeStamp containing the time stamp.

Throws:

TSPException - on a failure to parse the time stamp token data.

ERSException - on a failure to convert the time stamp token to an archive time stamp.
