Fundamentals of Secure Software - PKI (Public Key Infrastructure)

The video tutorial covers the concept of digital certificates and their role in public key infrastructure (PKI). It explains how digital certificates are used to verify the ownership of public keys and the role of certificate authorities (CAs) in issuing these certificates. The tutorial also describes the process of creating a certificate signing request (CSR) and how digital certificates can be viewed in a browser. Additionally, it discusses potential vulnerabilities in PKI, such as man-in-the-middle attacks, and emphasizes the importance of securing root certificates.
