Public Key Infrastructure (PKI) is a technology framework that secures communications in the digital world. It utilizes the principles of asymmetric cryptography to encrypt and digitally sign data, ensuring confidentiality, authenticity, and integrity. Coursera's PKI catalogue will guide you through the intricate processes of creating, managing, distributing, using, storing, and revoking digital certificates. You'll learn about critical components such as Certificate Authority (CA), Registration Authority (RA), and certificate revocation lists (CRLs). Furthermore, you'll grasp the role of PKI in secure email, secure remote access, secure web browsing, and secure e-commerce transactions. This knowledge will empower you to design and manage secure, scalable, and efficient communication systems and pave the way for a promising career in cybersecurity.
