SujoySengupta/caeser_cipher

This is a python program which implements the Caesar cipher, a cryptographic technique used for encoding and decoding messages by shifting the characters in the alphabet.

Caesar Cipher Project

Introduction

This project implements a simple Caesar Cipher algorithm to encode and decode messages. The Caesar Cipher is a type of substitution cipher where each letter in the plaintext is shifted a certain number of places down or up the alphabet.

Features

• Encoding: Convert plaintext into ciphertext by shifting letters.
• Decoding: Convert ciphertext back into plaintext.
• User-Friendly Interface: Easy-to-use web interface for encoding and decoding messages.

Installation

1. Clone the repository:

   git clone https://github.com/SujoySengupta/caeser_cipher.git

2. Navigate to the project directory:

   cd caeser_cipher/Caesar_Cipher_project

3. Install the required dependencies:

   pip install flask

Usage

1. Run the main script:

   python main.py

2. Open your web browser and go to http://localhost:5000.
3. Use the web interface to encode or decode your messages.
