In this episode of the Security Repo Podcast, software engineer and newly minted CISSP Matt Olmsted joins us to explore cryptographic fundamentals and why understanding them matters for anyone in security. From explaining symmetric vs. asymmetric encryption to the real-world implications of side-channel attacks, Matt delivers practical insights for blue teamers and developers alike. Plus, we dive into his journey in InfoSec, his unique use of podcasting tech to distribute ocarina music, and even enjoy a live performance to close the show.https://mattthetall.site/https://www.linkedin.com/in/matthew-olmsted/Matt Olmsted has worked professionally in software engineering for over a decade, and been interested in infosec his entire career. In 2024 he decided to go for the CISSP as his first infosec cert and passed the exam at the minimum number of questions after only studying two weeks. He's something of a polymath and renaissance man, the latter in both a literal and figurative sense.
