It’s long overdue, but more and more applications, systems, and services are finally requiring a PKI (Public Key Infrastructure). Sadly, however, any Google or Bing search on the subject will point you to sources that are incomplete, contradictory, or flat-out wrong. There just isn’t a lot of clear and concise information for administrators who are learning and implementing this growingly important and necessary technology. No longer! In this presentation we’ll learn about encryption, keys, hashing, certificates, revocation lists, certification authorities (offline and online, root and subordinate, policy and issuing), digital signatures, and more. This presentation is a must for any modern-day infrastructure administrator!
