# PDF Security Package

## Introduction

Sign a PDF document using a digital certificate, to allow the recipient to verify both the origin and the integrity of the file. This means that the recipient can verify that the PDF document came from your organization and has not been changed since it was created.

The PDF Security module can encrypt and sign PDF documents and decrypt and verify passwords included in PDF documents.

## Dependencies

Lasernet Base Server Package including XML in & out

## Recommended

- Conversion Package to secure PDF documents created by Lasernet
