Verify Digital Signature in Documents using C#

Digital Signatures in documents look similar to the paper-based signatures, however, being certificate-based electronic signatures they contain the identity of the signer in encrypted form.

This is why the digitally signed documents can be verified at any time. In this article, I’ll show you how to programmatically verify the digital signature in PDF, Word, and Excel, documents by using GroupDocs.

Introducing a More Optimized and Simplified Electronic Signature API

Why change is considered as a hard but yet good thing to occur? Why the updates are important? This is because if there is no change there is no progress and staying the same over the time makes the things die. The updates in the software components are also similar when a new version of the same software replaces the old one. A software that remains the same and doesn’t introduce any improvements or new features becomes obsolete.
