Method Detail

getDocumentTimeStamp

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

Extract the timestamp token object from the document timestamp.

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

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

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

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

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

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).

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

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

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).

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
