You'll need to extend TSAClient. Have a look at TSAClientBouncyCastle.java for 
inspiration.

Subject: [iText-questions] low-level timestamping process

Hi,
  Im writing an app for signing and timestamping PDFs using iText and Java.
Because we (in Slovenia) have different approach for getting timestamp from
our TSA (via web service, using certificate and password) I cannot use those
methods from iText. I have a Perl script for the web service part.

In the web service response I get timestamp's data as:

ds:DigestValue -> kERrAqmqAnNwT6QN2N/CtRRhgcM=
ts:SerialNumber -> 102299729497066078981007067333873907241223
ts:CreationTime -> 2011-04-26T11:55:53.075Z
ts:Nonce -> 11502067732787705978


How can I write those data in PDF, so the PDF reader will recognise them as
TSA timestamp, not as timestamp "from signer's computer"?
Which part of iText code writes those timestamp data into a PDF file?
Which metods do I need to override? Can I see this deep into the code?

thanks
