Method Detail

getSigningTime

public java.util.Calendar getSigningTime()

Description copied from interface: PdfSignatureDetails

Get the time of signature creation. If included the time given by the signature timestamp is used. Otherwise the time given in the PDF signature dictionary is returned.

Specified by:

getSigningTime in interface PdfSignatureDetails

Returns:

time of signature creation

getDocumentTimeStamp

public iaik.tsp.TimeStampToken getDocumentTimeStamp()
                                             throws PdfSignatureException,
                                                    java.io.IOException

Description copied from interface: DocumentTimestamp

Extract the timestamp token object from the document timestamp.

Specified by:

getDocumentTimeStamp in interface DocumentTimestamp

Returns:

the included timestamp token

Throws:

PdfSignatureException - if the timestamp can't be parsed

java.io.IOException - if the timestamp can't be extracted

getLTVParams

public PadesLTVParameters getLTVParams()
                                throws PdfSignatureException,
                                       java.io.IOException

Description copied from interface: DocumentTimestamp

Get the LTV data protected by this document timestamp (all ltv data up to timestamp creation)

Specified by:

getLTVParams in interface DocumentTimestamp

Returns:

the LTV data

Throws:

PdfSignatureException - if some ltv data can't be parsed

java.io.IOException - if some ltv data can't be read

verifyDocumentTimestamp

public void verifyDocumentTimestamp(iaik.x509.X509Certificate tsa_certificate)
                             throws iaik.tsp.TspVerificationException,
                                    PdfSignatureException,
                                    java.io.IOException

Description copied from interface: DocumentTimestamp

Verify the included timestamp, i.e. verify the timestamp's signature value and that the timestamped data has not been changed (that the timestamped data equals the document's content).

Specified by:

verifyDocumentTimestamp in interface DocumentTimestamp

Parameters:

tsa_certificate - timestamp authority's certificate if not included in the timestamp

Throws:

iaik.tsp.TspVerificationException - if signature of timestamp token is invalid or timestamp can't be parsed

PdfSignatureException - if the timestamp or the tsa certificate can't be extracted or if timestamped data has been changed

java.io.IOException - if errors occur when reading the timestamp or timestamped data

verifyDocumentTimestamp

public void verifyDocumentTimestamp()
                             throws iaik.tsp.TspVerificationException,
                                    PdfSignatureException,
                                    java.io.IOException

Description copied from interface: DocumentTimestamp

Verify the included timestamp, i.e. verify the timestamp's signature value and that the timestamped data has not been changed (that the timestamped data equals the document's content).

Specified by:

verifyDocumentTimestamp in interface DocumentTimestamp

Throws:

iaik.tsp.TspVerificationException - if signature of timestamp token is invalid or timestamp can't be parsed
