You're Storing Passwords Wrong. Here's The Fix

Hashing vs encryption - they're NOT the same, and confusing them is how security disasters happen. Learn how hashing actually works, why MD5 and SHA-1 are broken, and why bcrypt/Argon2 are the only correct choices for password storage.

In this video, you'll learn:

Why hashing is a one-way function
The difference between hashing and encryption
Why MD5 and SHA-1 should never be used for passwords
How rainbow tables crack passwords instantly
What salting is and why it matters
Why bcrypt and Argon2 are intentionally slow (and why that's good)

6:04 - Solution #2: bcrypt & Argon2
8:08 - Common mistakes to avoid
8:43 - Quick recap

KEY TAKEAWAYS:
→ Hashing is irreversible, encryption is reversible
→ Never use MD5, SHA-1, or even SHA-256 for passwords
→ Always use bcrypt or Argon2 - they handle salting automatically
→ Slow hashing protects users, fast hashing helps attackers

If you're storing passwords with MD5 or SHA-256, you need to watch this. One function call with the right library - that's all it takes to do password security correctly.
