Hi, I basically need to verify the date on which the document was signed.
The current implementation validates the expire date of the certificate, but I need to know if the PDF was signed during a valid period. (I will also get the certificate revocation status later by ocsp protocol).
I can use authenticity && integrity instead of the current authenticity && integrity && !expired, but I need to get the sign date.
Can it be done? Thanks in advance.
