Demo of md5 shows a dictionary crack in ~2 seconds; PBKDF2 with iteration count 10,000 slows checks but cloud buys CPU so cost matters more than time; bcrypt is common but still CPU-only; modern choice is argon2 — memory‑hard so GPUs do far fewer parallel hashes (example: 12GB GPUs only run ~24 heavy instances comfortably); built a secure-password native binding atop libsodium with prebuilt binaries and async worker threads to avoid blocking Node and to keep hashing expensive for attackers while remaining responsive for users.
