When you visit some webpages encrypted with SSL, you may be presented with a warning about the site's security certificate not being trusted. These are normally important screens to pay attention to, but UMIACS goes to great lengths to maintain a secure environment for our users. We provide a UMIACS CA (certificate authority) that enables your web browser to trust our secure webpages. The following steps explain how to import this certificate.

Due low level differences of Linux, accepting the root certificate at the operating system level is nontrivial. If you need assistance accepting the certificate for any other browser, please contact [[HelpDesk|UMIACS Staff]].

Introduction

When you visit webpages encrypted with SSL, you may be presented with a warning about the site's security certificate not being trusted. These are normally important screens to pay attention to on the internet as a whole and UMIACS goes to great lengths to maintain a secure environment for our users. However, it is not cost effective to provide commercial certs for all our public facing certificates. In order to keep costs down we provide a UMIACS CA (certificate authority) that enables your web browser to trust our secure webpages. The following steps explain how to import this certificate based on your preferred web browser.

Windows

For most Windows browsers (Chrome, Firefox, Edge and Internet Explorer), certificate authorities are handled by Windows itself. These are the steps required to accept the certificate:
