SHA-3 Visualizer

A real-time 3D visualization of the SHA-3 (Keccak) cryptographic hash function with step-by-step execution, built with Rust and Bevy. The internal 1600-bit state is rendered as a 5x5x64 matrix of cubes, with each transformation step color-coded across 24 rounds.

Visual Elements

• Red — Theta (column mixing)
• Green — Rho (bit rotation)
• Blue — Pi (lane rearrangement)
• Magenta — Chi (non-linear transformation)
• Yellow — Iota (round constant addition)

Controls

• Left mouse + drag to orbit, right mouse to pan, scroll to zoom
• ENTER to step through transformations
• P to toggle auto-animation, R to reset, F to fast-forward

Tech Stack

• Rust — core implementation
• Bevy 0.14 — 3D rendering engine
• Keccak-f[1600] — complete permutation with SHA3-256 verification
