StegaX
An open-source mobile application for securely embedding encrypted messages inside images using steganography.
The Problem
Most messaging systems rely on visible encryption but do not conceal the existence of sensitive data, making it easier to detect and target.
Approach
Built a Flutter application that combines AES-256-GCM encryption with on-device steganography. Ensured complete local processing with no external data transfer, and designed a clear separation between UI and cryptographic logic for maintainability and security.
My Role
Designed and developed the entire application, focusing on secure data handling, encryption workflows, and building a clean and reliable user interface.
Outcome
Delivered a privacy-focused application that enables secure and discreet communication, while demonstrating strong fundamentals in cryptography and secure system design.
