Secupy Library

Overview

Secupy is a Python-based library designed for secure encryption, hashing, communication, and asymmetric encryption operations. It helps developers integrate security features such as message signing, password hashing, encryption/decryption, and asymmetric encryption into their applications seamlessly.

This library provides a simple and efficient way to handle various security tasks, making it ideal for use in applications that require data protection and secure communications.

Usage

Below are examples of how to use each module in both Flask and Django applications.

---

1. Encryptor: Symmetric Encryption and Decryption

The Encryptor class uses the Fernet encryption method to encrypt and decrypt messages securely.

Flask Example:

from flask import Flask, request, jsonify
from secupy import Encryptor

app = Flask(__name__)

@app.route('/encrypt', methods=['POST'])
def encrypt_message():
    message = request.json.get('message')
    encryptor = Encryptor()
    encrypted = encryptor.encrypt(message)
    decrypted = encryptor.decrypt(encrypted)
    return jsonify({"Encrypted": encrypted, "Decrypted": decrypted})

if __name__ == '__main__':
    app.run(debug=True)

Django Example:

from django.http import JsonResponse
from secupy import Encryptor

def encrypt_message(request):
    message = request.POST.get('message')
    encryptor = Encryptor()
    encrypted = encryptor.encrypt(message)
    decrypted = encryptor.decrypt(encrypted)
    return JsonResponse({"Encrypted": encrypted, "Decrypted": decrypted})

---

2. Hasher: Password Hashing and Verification

The Hasher class uses bcrypt for securely hashing and verifying passwords.

Flask Example:

from flask import Flask, request, jsonify
from secupy import Hasher

app = Flask(__name__)

@app.route('/hash-password', methods=['POST'])
def hash_password():
    password = request.json.get('password')
    hasher = Hasher()
    hashed_password = hasher.hash_password(password)
    is_valid = hasher.verify_password(password, hashed_password)
    return jsonify({"Hashed Password": hashed_password, "Password Valid": is_valid})

if __name__ == '__main__':
    app.run(debug=True)

Django Example:

from django.http import JsonResponse
from secupy import Hasher

def hash_password(request):
    password = request.POST.get('password')
    hasher = Hasher()
    hashed_password = hasher.hash_password(password)
    is_valid = hasher.verify_password(password, hashed_password)
    return JsonResponse({"Hashed Password": hashed_password, "Password Valid": is_valid})

---

3. SecureCommunicator: Message Signing and Verification

The SecureCommunicator class uses HMAC with SHA-256 to securely sign messages and verify their authenticity.

Flask Example:

from flask import Flask, request, jsonify
from secupy import SecureCommunicator

app = Flask(__name__)

@app.route('/secure-message', methods=['POST'])
def secure_message():
    message = request.json.get('message')
    secret_key = "your_secret_key"
    communicator = SecureCommunicator(secret_key)
    signature = communicator.generate_signature(message)
    is_valid = communicator.verify_signature(message, signature)
    return jsonify({"Message": message, "Signature Valid": is_valid})

if __name__ == '__main__':
    app.run(debug=True)

Django Example:

from django.http import JsonResponse
from secupy import SecureCommunicator

def secure_message(request):
    message = request.POST.get('message')
    secret_key = "your_secret_key"
    communicator = SecureCommunicator(secret_key)
    signature = communicator.generate_signature(message)
    is_valid = communicator.verify_signature(message, signature)
    return JsonResponse({"Message": message, "Signature Valid": is_valid})

---

4. AsymmetricEncryptor: Asymmetric Encryption and Decryption

The AsymmetricEncryptor class uses RSA for asymmetric encryption and decryption, allowing secure communication between two parties with private and public keys.

Flask Example:

from flask import Flask, request, jsonify
from secupy import AsymmetricEncryptor

app = Flask(__name__)

@app.route('/asymmetric-encrypt', methods=['POST'])
def asymmetric_encrypt():
    message = request.json.get('message')
    asymmetric = AsymmetricEncryptor()
    encrypted_message = asymmetric.encrypt(message)
    decrypted_message = asymmetric.decrypt(encrypted_message)
    return jsonify({"Encrypted Message": encrypted_message, "Decrypted Message": decrypted_message})

if __name__ == '__main__':
    app.run(debug=True)

Django Example:

from django.http import JsonResponse
from secupy import AsymmetricEncryptor

def asymmetric_encrypt(request):
    message = request.POST.get('message')
    asymmetric = AsymmetricEncryptor()
    encrypted_message = asymmetric.encrypt(message)
    decrypted_message = asymmetric.decrypt(encrypted_message)
    return JsonResponse({"Encrypted Message": encrypted_message, "Decrypted Message": decrypted_message})

---

5. KeyManager: Key Generation for Encryption

The KeyManager class generates secure cryptographic keys using PBKDF2 with a password.

Flask Example:

from flask import Flask, request, jsonify
from secupy import KeyManager

app = Flask(__name__)

@app.route('/generate-key', methods=['POST'])
def generate_key():
    password = request.json.get('password')
    key_manager = KeyManager()
    key, salt = key_manager.generate_key(password)
    return jsonify({"Generated Key": key, "Salt": salt})

if __name__ == '__main__':
    app.run(debug=True)

Django Example:

from django.http import JsonResponse
from secupy import KeyManager

def generate_key(request):
    password = request.POST.get('password')
    key_manager = KeyManager()
    key, salt = key_manager.generate_key(password)
    return JsonResponse({"Generated Key": key, "Salt": salt})
