How do I implement salt in my application?

Implementing salt involves adding a unique, random value to each password before hashing it. Would you like a code example?

Yes, please provide a code example for that.

Here's a simple example in Python:

import os
import hashlib

def hash_password(password):
    salt = os.urandom(16)  # Generate a random salt
    salted_password = salt + password.encode()
    hashed = hashlib.pbkdf2_hmac('sha256', salted_password, salt, 100000)
    return salt + hashed  # Store both salt and hash

How do I verify the password later?

To verify, extract the salt from the stored hash, hash the input password with that salt, and compare the hashes.
