Overview

StegoPlus is a Rust-based desktop application built with Tauri that encrypts passwords using AES-GCM and embeds them inside PNG images using LSB steganography.

Architecture

• Rust core
• AES-256-GCM encryption
• Diceware-style passphrase handling
• PNG LSB embedding
• Cross-machine validation testing

Security Model

The application encrypts the payload before embedding. Steganography provides concealment, not cryptographic security.

Lessons Learned

• GUI architecture in Tauri
• Rust cryptography crates
• Cross-system validation testing
• Real-world delivery constraints (email + cloud storage validation)
