Delbeke has managed to do something that we never thought we would see
with this library: a major new feature. Well done Delbeke! He has added support for digital signatures.
This new version is provided by member_profile.asp?PF=129 - Delbeke and is available in the source code area [ http://www.quickpdf.org/forum/forum_posts.asp?TID=940 - here ]. Please note that you need to own the source code and have the password to access this area of the forum.
A "pre-compiled" and "DCU" versions of the library will be made available in the near future once development and testing of the new version has been completed.
List of Changes
- Added ability to digitally sign a PDF file.
Notes
- Note that this code is preliminary and that checks and security
test code still needs to be added. However, if all of your parameters
are correct, the program works!
- You need to have CAPICOM.dll registered on your machine. This
file is distributed by Microsoft. More information is available from
Microsoft [ http://msdn.microsoft.com/en-us/library/aa388154.aspx - here ].
