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:
  • What cryptography actually protects (and what it doesn’t)
  • The basics of symmetric vs. asymmetric encryption
  • How hashing, digital signatures, and key exchange work
  • Why randomness and entropy matter so much
  • Common developer mistakes — and how to avoid them
Through clear visuals and real-world examples, you’ll leave with a solid mental model of how cryptography works — and the confidence to apply it correctly in your own projects.
