Many developers use cryptography without fully understanding how it works — and that’s where things often go wrong. Misapplied crypto can quietly weaken the security of an entire system.
In this talk, we’ll break down the core building blocks of modern cryptography in a way that’s practical and easy to grasp — no PhD required. You’ll learn:
