🔐 Hash a Password with Python

Secure your passwords by hashing them with Python and the hashlib library!

First, install the necessary module:

pip install hashlib

Then, use this script:

import hashlib

# https://t.me/LearnPython3

def hash_password(password):
    # Create a new sha256 hash object
    hash_obj = hashlib.sha256()
    # Update the hash object with the bytes of the password
    hash_obj.update(password.encode('utf-8'))
    # Return the hexadecimal representation of the hash
    return hash_obj.hexdigest()

password = 'mypassword'
hashed_password = hash_password(password)
print(hashed_password)

Ensure your passwords are secure by hashing them before storing!
