Want to stop attackers from cracking passwords? In this Cyber Security Tutorial, we explain how hashes work, common attacks on hashes, and the best practical defenses you should implement today: salt & pepper, Argon2/bcrypt, MFA, rate-limiting, HSMs and monitoring. This is a must-watch for developers, sysadmins, and security beginners.

What you’ll learn:
What is a hash & key hash properties (deterministic, fixed-length, one-way, avalanche)
Common hash types (MD5, SHA-1, SHA-256) and password hashes (bcrypt, scrypt, Argon2)
Salting vs Peppering — why both matter and how to implement them
Offline vs Online attacks — why offline hash leaks are dangerous
Attack techniques: rainbow tables, brute-force, dictionary attacks, collisions
Tools overview: John the Ripper, Hashcat, Hydra — use-cases & limits
Practical defenses: slow & memory-hard hashing, unique salts, MFA, rate-limiting, monitoring, secret rotation, HSMs
Real-world best practices & checklist for secure password storage

Actionable steps shown in the video:
* Migrate old password hashes → Argon2 (example config notes)
* Add unique salt & rotate pepper (store pepper securely)
* Enforce MFA + rate limiting + account lockouts
* Set up monitoring & alerting for brute-force patterns
* Secure backups and DB access (least privilege, rotated keys)
