Krazy is just fine, and thanks for the reply. ok, its a good practice. but, assuming the person opening the pdf does not have an active internet connection, the signature will appear as "validity unknown". if i let reader access the internet, then it verifys the OCSP and gives valid signature. this is for the pdf signed with itext.
the one signed in acrobat professional, gives valid both ways. Is there anything i have to had in the one i sign with itext, to have the same behavior as the one signed in acrobat ? thanks. Regards.
