How to Install the cesb.uky.edu Certificate Authority


Why Install?

Installing the certificate will make all of those annoying warning messages about unknown web certificates go away.

Why do we have a Certificate Authority?

Every secure http site (https) uses an SSL certificate. Most certificates come ultimately from one of the big certificate authority companies like Verisign.
Websites with SSL certificates are then automatically verified by these certificate authority companies.
But these companies charge money for SSL certificates. For domain wildcarded certificates like we have, it is typically over $1000/year.
In order not to pay this, we have generated our own self-signed certificate authority.
