“TLS Demystified: Certificates, Keys, and Trust in Practice” – Илиян Илиев

This talk delves into the essential role of TLS in internet communication, emphasizing its status as a foundational requirement rather than a luxury. The speaker provides a practical examination of how TLS operates, covering key concepts such as symmetric and asymmetric encryption, the establishment of trust through certificates and certificate chains, and the securing of communication via the TLS handshake. Additionally, the session addresses mutual TLS (mTLS), common challenges in certificate management, and real-world examples where the trust model has encountered failures.
