Encryption & Hashing using Python

This project demonstrates how to encrypt and hash data securely using Python. It includes examples of symmetric encryption (AES), hashing with SHA-256, and secure password handling with bcrypt.

Key Features

Encrypt text using AES encryption (from the cryptography library)
Hash data using SHA-256 and SHA-512
Secure password storage using bcrypt
Python script input/output for easy testing

Sample Code Snippets

SHA-256 Hashing

import hashlib

text = "SecureMessage123"
hashed = hashlib.sha256(text.encode()).hexdigest()
print("SHA-256 Hash:", hashed)

AES Encryption

from cryptography.fernet import Fernet

key = Fernet.generate_key()
cipher = Fernet(key)
message = b"Encrypt this text"

encrypted = cipher.encrypt(message)
decrypted = cipher.decrypt(encrypted)

print("Encrypted:", encrypted)
print("Decrypted:", decrypted)

Password Hashing with bcrypt

import bcrypt

password = b"SuperSecretPassword"
salt = bcrypt.gensalt()
hashed = bcrypt.hashpw(password, salt)

print("Hashed password:", hashed)
