CLI (Command Line Interface) for signing PDF files (3)

We need a Command Line interface for signing PDF files on the fly, with PFX certificate.

The PDF must be Certified, please see attached example image.

The PFX Certificate path and password should be passed by parameter as well as input and output of the PDF file.

The signing process should also timestamp the PDF files with a timestamp server like [login to view URL]

The signature should be invisible.

On certifying: No Changes Allowed

If it could sign multiple PDF files at the same time, the better.

Thank you!

Important: The solution provided shoud not require any installation like .NET or some other files, it should be just an portables executable PE file. Or it could have some external files since all of them are in the same folder of our invoicing software, from which we are going to call the program.

Skills: .NET, C Programming, C# Programming, C++ Programming
