Password Hashing in Python

#python #security #learning #discuss

One must never store passwords plainly. Let's learn the technique of hashing passwords securely using Python:

import hashlib

password = "securepassword"

hashed = hashlib.sha256(password.encode()).hexdigest()

print(f"Hashed password: {hashed}")

Hashing means that even if someone manages to break into the database, they will not get to know what the plaintext passwords are. Now, most modern systems use advanced algorithms like bcrypt, which also include salting.

Pro tip: Never ever roll out your own cryptographic stuff; it will lead you nowhere. Just use proven libraries like bcrypt or argon2.

This builds trust and makes the user secure.
