Welcome to Public-Key Infrastructures

PKI's (Public-Key Infrastructures) enable the use of encryption and digital signatures (digital ID's) across a wide variety of platforms and applications.

Use the navigation bar to the left or click on any of the links on this page for additional information and tutorials on requesting a PKI account or installing and utilizing encryption software.

If you have any questions or concerns, please contact us at: 618-453-5155. We are happy to assist you!  

 Register for a Digital Signature. This allows you to digitally sign forms and send or receive sensitive information in an encrypted form to protect your privacy as well as the information being sent.

The Entrust Entelligence Security Provider (EESP) is a Microsoft Windows based client application that helps manage the use of State of Illinois Entrust Digital IDs. Learn how to set up and use your Digital ID.

Most forms that allow for digital signing are in PDF format and as such require the use of Adobe Reader. Download the latest version of Adobe Reader here.
