Скачать или смотреть Hashlib: Secure Password Hashing Starts Here

Learn how to securely hash passwords in Python using the built-in hashlib library. In this step-by-step tutorial, you’ll understand how SHA-256 works, how to generate secure password hashes, how to verify passwords, and the security limitations of SHA-256 alone.
Perfect for beginners and anyone learning cybersecurity, authentication systems, or Python backend fundamentals.

What you’ll learn:

What hashing is and why it matters

How to use hashlib in Python

How SHA-256 hashing works

How to hash and verify passwords

Common mistakes (e.g., why hashing ≠ encryption)

What to use instead for real-world apps (PBKDF2, bcrypt, Argon2)

Code used in the video:

import hashlib

password = "mypassword123"
hashed = hashlib.sha256(password.encode()).hexdigest()
print(hashed)
