PolyShift Cryptographic System

Overview

A custom multi-layered cryptographic system combining 7 security components including SHA-256 key derivation, Spiral Matrix Transformation, and dynamic encryption rounds (8–20) based on password strength. Built with a team of 3 developers.

Key Highlights

• Spiral Matrix Transformation for positional diffusion and frequency analysis resistance
• Dynamic encryption rounds (8–20) adapting automatically to password strength
• Checksum verification using SHA-256 for data integrity and tamper detection
• Java Swing desktop GUI with real-time password strength meter and file encryption support
