How To Set Up A Certificate Authority In 10 Minutes, March 28, 2012 Having a company owned certificate authority makes managing your network devices simpler and more secure. There is nothing inherently wrong with self-signed certs, but you can do better. You can build a CA issue your first certificate in about 10 minutes. Here is how to do it.
Set the common name. For a SSL/TLS certificate, this must match the DNS name of the target site or you will get an error when you try to access the site because the SSL client should compare the DNS name entered in the browser against the common name in the certificate. You can use wildcard DNS names that match any hostname within a domain, but it's generally a bad practice unless you have a compelling reason. Let's not go there.
Fill in the country, state, and city fields. Just enter what ever is meaningful to you. It doesn't technically matter. Pick a file name and location to save your certificate request.
