Pragmatically, a PKI is an operational system that employs asymmetric cryptography, information technology, operating rules, physical and logical security, and legal matters. Much like any technology, cryptography in general undergoes changes: sometimes evolutionary, sometimes dramatically, and sometimes unknowingly. This book discusses whatnot do in PKI operations. Providing a no-nonsense approach and multiple case studies, the book is a straightforward, real-world guide to how to successfully operate a PKI system.
