Encoder-Decoder App The Encoder-Decoder app is a Python application that enables users to encrypt and decrypt messages and images using cryptography techniques. It consists of two main components: the sender and receiver modules.

Sender Module The sender module allows users to encrypt messages and images before sending them to a receiver. Users can input plaintext messages or select an image file to encrypt. The app encrypts the data using a generated key and sends it to the receiver via HTTP POST requests.

Receiver Module The receiver module receives encrypted messages and images from the sender and decrypts them using the shared key. It saves decrypted images to a designated folder and maintains a chat history of received messages. The receiver responds with the decrypted message or confirmation upon successful reception.

Features Encrypt plaintext messages and images Decrypt received messages and images Store chat history of sender and receiver Simple HTTP endpoints for sending and receiving encrypted data Usage Run the sender module (sender.py) to encrypt and send messages or images. Run the receiver module (receiver.py) to receive and decrypt messages or images. Dependencies requests library for handling HTTP requests Flask library for building web applications cryptography library for encryption and decryption How to Run Install dependencies: pip install requests flask cryptography Run sender module: python sender.py Run receiver module: python receiver.py
