Hi Tomas, your requirement is not related to iText. You want to verify a blob against a detached signature. This is the domain of the crypto provider like e.g. Bouncy Castle. You'll find samples there ...
Or you can take a look at our verification web site http://sig-check.de . We are going to verify both, PDF included signatures or detached ones. The code is open source, available at http://sourceforge.net/projects/sirius-sign/ Greetings Andreas ----- original Nachricht -------- Betreff: [iText-questions] verification of external signature Gesendet: Fr, 12.
