The Role of CAs in PKI

Hi,


This question concerns the role of certificate authorities. How I understand PKI thusfar is that it's simply the use of asymmetric cryptography to protect data. I hope that much I have right.

Next, I've been looking for info on what exactly CAs do. What is their role in all of this? In other words, would it be possible to have PKI without a certificate authority and have each keep and issue their own public/private key pair?

If anyone is confused I can clarify this.
