Hello,
I have a different requirement, pdf is encrypted by using a key and that encrypted pdf will be sent to client, when anybody opens
that pdf, it asks for key, if right key applied pdf should be decrypted and displayed.
I have used RijndaelManaged Algorithm for encrypting pdf file, pdf is getting encrypted, but when i double click on that
encrypted pdf its not asking for key. It should ask for key and pdf will be decrypted and will be opened.
I have two programs , one for encryption , one for decryption. I am successfully encrypting and decrypting by using those
prg's. but for decrypting i cannot use program, when we double click on file then only decryption program runs and check
for right key, should be decrypted.
I have been really searching for this specific thing for the past 48 hours. I did not find any solution.
Please help me out from this problem...
