Entrust | Information Security

This document consists of a single workflow to use Entrust to encrypt/sign a file for multiple users.

Prerequisites:

• You must already have an Entrust account (see How to Create a State of Illinois Entrust PKI Account).

• You must already have the Entrust client installed (see How to Install the Entrust EESP Client for Windows).

About this workflow: The example screenshots below were created in June, 2010, using Windows Vista. You may desire to review the entire workflow before beginning.

The workflow starts on the next page.
