I've been doing the same thing. One reason is the complexity in some of the cert replacements. If you don't do them
often enough, you can actually spend a lot of time figuring out the process for quirky applics. Plus you limit the
risk. It's not hard fast rule for us though. I use a longer cert if there is a compelling reason to do so. In some
cases, I do use 1 year certs as well. Wildcard certs may need a longer timeline if you use them a lot of places so
that you have time to deal with all the renewals.

As a quick followup. What is general practice for the age of certificates? I have an informal practice of renewing
every 2 years, as a balance between convenience and attempting to change out the keys once in a while. I'd be
interested if anybody has any strong feelings one way or another on this issue as well.

I've got an administrator who is pushing me towards using a wildcard certificate for our domain. I don't like the
idea because if one server compromises the private key, all the other servers' ssl is also potentially compromised.
Does anybody have any evidence or opinion for or against you'd be willing or eager to share?
