Constructor Detail

TSPTimeStampTokenImpl

public TSPTimeStampTokenImpl(iaik.tsp.TimeStampToken token)

Creates a new instance of this TSPTimeStampTokenImpl with the given TSP time-stamp token.

Parameters:

token - the TSP time-stamp token.

Throws:

NullPointerException - if token is null

TSPTimeStampTokenImpl

public TSPTimeStampTokenImpl(byte[] token)
                      throws TimeStampTokenException

Creates a new instance of this TSPTimeStampTokenImpl with the given DER encoded TSP time-stamp token.

Parameters:

token - the DER encoded TSP time-stamp token (RFC3161).

Throws:

TimeStampTokenException - if token is not a valid DER encoded TSP time-stamp token according to RFC3161.

NullPointerException - if token is null

Method Detail

getDEREncoded

public byte[] getDEREncoded()
                     throws TimeStampTokenException

Description copied from interface: TSPTimeStampToken

Returns the DER encoded time stamp-token.

Specified by:

getDEREncoded in interface TSPTimeStampToken

Returns:

the DER encoded time stamp-token

Throws:

TimeStampTokenException

See Also:

TSPTimeStampToken.getDEREncoded()

getTimeStampToken

public iaik.tsp.TimeStampToken getTimeStampToken()

Returns:

the TimeStampTokenwrapped by this TSPTimeStampToken

getTSAIdentifier

public String getTSAIdentifier()

Description copied from interface: TimeStampToken

Returns the identifier of the TSA that issued the time-stamp token.

Specified by:

getTSAIdentifier in interface TimeStampToken

Returns:

the identifier of the TSA, or null if the TSA's identifier is not present in the time-stamp token.

See Also:

TimeStampToken.getTSAIdentifier()

getTSACertificate

public X509Certificate getTSACertificate()

Description copied from interface: TimeStampToken

Returns the certificate of the TSA that issued the time-stamp token, if the certificate is present in the time-stamp token.

Specified by:

getTSACertificate in interface TimeStampToken

Returns:

the certificate of the TSA, or null if the TSA's certificate is not present in the time-stamp token.

See Also:

TimeStampToken.getTSACertificate()

getSerialNumber

public BigInteger getSerialNumber()

Description copied from interface: TimeStampToken

Returns the serial number of the time-stamp token.

Specified by:

getSerialNumber in interface TimeStampToken

Returns:

the serial number of the time-stamp token

See Also:

TimeStampToken.getSerialNumber()

getTime

public Date getTime()

Description copied from interface: TimeStampToken

Returns the generation time of the time-stamp token.

Specified by:

getTime in interface TimeStampToken

Returns:

the generation time of the time-stamp token

See Also:

TimeStampToken.getTime()

getAccuracy

public long getAccuracy()

Description copied from interface: TimeStampToken

Returns the accuracy of the time-stamp token in milliseconds.

A negative value indicates that no accuracy is given in the time-stamp token.
