Encrypted Messaging Platform

Encrypted Messaging Platform

Introduction

In an era where data privacy is under constant threat, the demand for secure communication platforms is greater than ever. Messaging apps today serve as essential tools for both personal and professional communication, yet most are prone to vulnerabilities like eavesdropping, man-in-the-middle (MITM) attacks, and data leaks. With growing awareness of digital surveillance and increasing cybercrime incidents, ensuring end-to-end encryption in messaging systems has become a critical requirement.

The Encrypted Messaging Platform is a secure, locally-hosted web application built using HTML5, CSS3, JavaScript, Bootstrap, PHP, and MySQL, and run through XAMPP. This application empowers users to communicate confidently and securely using robust encryption techniques, including RSA, DES, AES, and ElGamal — each serving different cryptographic purposes.

Encrypted Messaging Platform not only simulates a real-world secure messaging service but also helps learners understand cryptographic implementation on a functional web interface. It demonstrates how secure communication can be practically implemented without relying on external platforms or APIs, making it a great educational tool for aspiring cybersecurity professionals, ethical hackers, or web developers.

Designed specifically for BCA, MCA, B.Tech (CSE/IT), and Diploma in Computer Science students, this project provides rich learning on:

• Web security fundamentals
• Cryptographic algorithms
• Full-stack web development
• Secure file sharing

Through Encrypted Messaging Platform project, students will also learn about encryption/decryption flow, session management, and the importance of safeguarding user data during real-time communication.

What makes this platform unique is its flexibility to choose different encryption techniques for different conversations. This not only strengthens security but also introduces students to comparative cryptography — understanding the pros and cons of each method.

Furthermore, since the application runs on a local server using XAMPP, it requires no internet connection and is suitable for offline demonstration and testing — making it perfect for classroom and lab environments.

Whether you’re aiming to showcase this in your final-year project, enrich your portfolio with cybersecurity projects, or develop a base for a real-world secure chat application, this project provides all the building blocks of a powerful secure messaging system.

Problem Statement

Traditional chat platforms often lack end-to-end encryption, leaving messages exposed to:

• Man-in-the-middle attacks
• Unauthorized access
• Sensitive data breaches

The Encrypted Messaging Platform addresses these concerns by:

• Integrating industry-standard encryption algorithms,
• Securing both text and media exchanges, and
• Providing a secure yet user-friendly chat interface.

Functionalities

User

• Register: Create a secure user account with validation.
• Login: Secure access through username and password.
• Chat: Send and receive messages encrypted via RSA, DES, AES, or ElGamal encryption methods.
• Share Media: Send encrypted media files (images, documents, etc.) in a secure environment.

Encryption Algorithms Used

Algorithm	Use Case
RSA	Asymmetric encryption for secure key exchange
DES	Symmetric encryption for short messages
AES	Symmetric, strong encryption for fast communication
ElGamal	Public-key encryption for added security in message sharing

Users may select or switch between these algorithms while chatting.

Technology Stack

Component	Technology Used
Front-End	HTML5, CSS3, JavaScript, Bootstrap 5
Back-End	PHP
Database	MySQL
Server	XAMPP
