QuickPDF v6.04.3 - Added Digital Signatures

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 Delbeke and is available in the source code area [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 [here].
