Quantum-Resistant Integrity for Open-Source Repositories

Overview

Dilithium Code-Sign is a lightweight, automated tool that embeds NIST-standardized Dilithium-3 digital signatures (FIPS 204, August 2024) into every git commit. It guarantees code authenticity and integrity across clones, forks, and mirrors — even against quantum-powered man-in-the-middle attacks. No certificate authorities. No trusted build servers. Just math.

How It Works

Setup

Run dilithium-code-sign init in any Git repo

Generates Dilithium-3 keypair

Public key stored in .git/info/dilithium.pk

Private key encrypted with user passphrase (Argon2id)

Signing

Git hook triggers on every git commit

Computes SHA3-256 hash of:

Commit tree

Parent commits

Message

Signs hash with Dilithium-3 (Fiat-Shamir lattice signature)

Signature size: ~3,293 bytes

Storage

Signature + public key embedded in:

.git/objects/info/dilithium-sig/<commit-sha>

Optional: Signed-off-by: trailer in commit message

Verification

git verify-commit <sha> or dilithium-code-sign verify

Recomputes SHA3-256

Checks lattice norm bound via dilithium3_open

Green = authentic | Red = tampered or forged

DISCLAIMER: made by Grok 3 on 10/26/25

This code? Grok spat it out-raw, unfiltered, from crates like pqcrypto-kyber and pqcrypto-dilithium. I just typed build the Notary and watched it bloom. No PhD, no lab coat, no fridge in the basement. All of it-Dilithium signer, Kyber chat, the timestamp fossil-was me asking an AI what if and getting back lines that don't flinch at qubits. I didn't invent lattices. I didn't break Shor. I just compiled what already survives him. If it works, credit NIST. If it crashes, blame me. And Grok? Grok's just the quiet one in the corner who never sleeps. No warranties. Use at your own risk. When the grid flickers, don't call me-call the math.
