data-encryption-using-python

This project demonstrates text encryption and decryption using Python. It applies basic cryptographic techniques to secure data and helps beginners understand how encryption works programmatically.

Python Encryption Projects

This repository contains a collection of Python-based encryption, hashing, and message authentication projects. It is designed for learning, experimentation, and demonstration of cryptography concepts using Python.

Features

  1. Text Encryption & Decryption CLI (encryption_tool.py)

    • Symmetric encryption using Fernet
    • Asymmetric encryption using RSA
    • Hashing using SHA-256

  2. AES File Encryption (aes_file_encryptor.py)

    • Encrypt and decrypt files using AES (EAX mode)
    • Generates a random AES key for each encryption
    • Saves encrypted files and allows decryption with the correct key

  3. File Hashing & Integrity Check (file_hash_checker.py)

    • Generate SHA-256 hash for any file
    • Verify file integrity using stored hash values

  4. AES & RSA Message Encryption CLI (aes_rsa_encryptor.py)

    • Demonstrates both AES symmetric and RSA asymmetric encryption
    • Allows encryption and decryption of user messages

  5. Digital Signatures & HMAC (digital_signature_hmac.py)

    • Create and verify RSA-based digital signatures
    • Generate and verify HMAC (SHA-256) for message authentication
