Hi All,

There is a function in PdfPKCS7 to verify a signature i.e. verify(), I want
know how it works.
If I create a pdf document & sign it, the above function returns false, if
later I change this pdf document (Adobe will tell the user that the document
is changed) and call verify(), I get false. I believe this function checks
the signed hash with the original hash which was present at the time of
signing. Why this function always return false ? In the iText signature
sample I always see Document modified: true

Whats the difference between verifySignature (Verifies a signature) of
AcroFields and verify of PdfPkcs7 ?

Regards,
Wahaj
