How to Secure User Passwords: From Weak Hashes to PBKDF2, bcrypt, and scrypt

This article examines common password‑storage techniques, explains why plain‑text, symmetric encryption, and simple hashes are insecure, and demonstrates how modern algorithms like PBKDF2, bcrypt, and scrypt, together with proper salting and iteration, can effectively protect user credentials against large‑scale cracking attacks.
