If not using timestamp service (RFC 3161) then can OCSP response time
(thisUpdate) be used as certified timestamp ? I mean even if OCSP response is embedded in signature, PDF Reader is complaining that "Signature date/time are from the clock on the signer's computer". ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.

no.
signature timestamp is the undeniable time of the signature; OCSP gives information about certificate status only. there is no signature involved.

Well, if OCSP is not a timestamp why should it behave like a timestamp?

You can keep repeating that until you turn blue but it won't the change the
fact that the PDFs don't work that way.You should ask those questions to Adobe.

If I trust OCSP response and certificate revocation status then why not trust the time the certificate was checked ? ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
