Hi Krazy ( or do you prefer Smile ? ),

it's always good practice to include the OCSP check when validating a 
signature. 
The problem ou're facing seems to stem from an unreachable OCSP responder or a 
broken OCSP reference within your certificate. Both shouldn't happen when using 
smart card based certificates. 

Maybe you can post the document ?

Greetings

Andreas

Subject: [iText-questions]  Signature "validity unknow"


Hello Everyone.

Ive got 2 signed pdfs.
one i sign with itext and a smartcard, and other a test pdf i sign with
acrobat professional and the same smartcard.
the only diference between them is the one signed in acrobat has :
"signature is timestamped".

now...

in adobe preferences - Security - advanced preferences, there is this a
check box:
"Require certificate revocation checking to succeed whenever possible during
signature verification".

if i leave it with the default value (checked):
the itext pdf, gives an "validity unknow";
the acrobat pdf gives a valid Signature;

if i uncheck it, they both give a Valid signature.

also, with the option checked, i get:
"Contacting http://adobe-ocsp.geotrust.com/responder for OCSP based
revocation checking, press ESC to cancel"


So, why am i getting the "validity unknow" ?
Is there any way to solve it?

Im only concerning this, because adobe reader, has by default, this option
checked.

Any help apreciated.

regards.
