The Automatic Certificate Management Environment (ACME) protocol makes it possible to obtain certificates from a certificate authority instantaneously without any human intervention. Developed and used by Let's Encrypt, a free and open-source certificate authority, this protocol has greatly simplified the once complex process for obtaining and managing server certificates. Since this protocol became an IETF standard a little over a year ago, more certificate authorities are now looking to implement this protocol. In this session, we'll first give an introduction to the ACME protocol and how it works. Then, we'll take a look at a Java ACME client that has been integrated in the WildFly application server and we'll demonstrate how to easily obtain and manage server certificates for WildFly from Let's Encrypt or any certificate authority that implements the ACME protocol. By the end of the session, you will understand the benefits of the ACME protocol and will never need to worry about forgetting to renew your server's certificate ever again.
