sign and timestamp PDF files

[GuTyKa]

Hi!

Is there a way to achieve signing and timestamping PDF files with Cryptlib or
with the aid of Crytplib?

Thank you!

Regards,
GuTyKa

PDF signatures use standard PKCS #7/SMIME signatures, so all you need to do is
embed a cryptlib detached signature in a PDF file.  cryptlib handles all of
the crypto, but you'll need to write your own code to process the PDF file.
