C# Encrypt existing PDF using a Certificate

[daniel685]

Hi all,

I am creating a component for a server based application where we take an existing PDF and want to apply encryption.

The certificate used to apply the encryption can be identified but I need help which Adobe component to be used best and which calls to be used best in a C# .NET 4.0 server application.

All users have Adobe Acrobat Standard installed on their machines.

Thanks

Daniel

You can't use Adobe Acrobat on a server.

That´s why I asked which Adobe component can be used.

Thanks

May be one of the LiveCycle server products.
