A Recipe for Password Storage: Add Salt to Taste
Nick Malcolm (Aura Information Security)
Every time a website gets breached you hope to hear “your password was salted and hashed: instead of “your passwords were stored in plain text” - but what does that actually mean, and why is it a good thing?
Wash your hands, don your apron, and join me for as we follow the recipe for storing passwords safely. We’ll learn a bit about cryptography and one-way functions (that’s the hash!), how to source good ingredients (bcrypt, scrypt, argon, oh my!), why adding a pinch of salt helps, how many times must we stir the mix, and what happens if we miss a step? In the face of an attacker, will our delicious password loaf rise to the occasion, or will it fall flat in disappointment and despair?!
