Course Description
Without a Public Key Infrastructure (PKI) we wouldn't have the Internet that we have today. Over 50% of all websites utilize Secure HTTP (HTTPS) which relies on a PKI and the exchange of Digital Certificates. Understanding the components of a PKI and how Digital Certificates provide security will help you whether you are the administrator of a secure website, studying for a security-related certification exam, or just curious about the process. This course will explain the components of the Public Key Infrastructure and introduce you to several of its critical elements such as; Asymmetric Key Encryption, Hash Algorithms, Trusted Root Certificate Authorities, how to view Digital Certificates and understand the fields within them, Certificate Revocation methods, and much, much more.
