- Certificates expire. We put in the expiration dates whenever we're creating them, right? So, we know they're going to expire. We have to prepare for it. So, you know, everything's all fine and dandy whenever you first create your certificates. You know, you do the ribbon cutting ceremony, everything's working great, you feel really proud of yourself, it's awesome. You've got a working certificate. Fantastic. But someday, that certificate is going to go bad. It is going to expire, like an old banana. And when it does, you're going to need to go out to the certificate authority that issued your certificate.
And this is either going to be the website of the company that issued and signed your certificate, or it's going to be the private CA that you created. So that's going to require you to open up your toolkit. Get in there and create a new, renewed certificate. And in this chapter we're going to teach you exactly how to do that. So everything will be okay.
