# QCrypt RNG

**Quantum-enhanced random number generation, post-quantum cryptography, and blockchain security.**

QCrypt RNG is a platform for cryptographically secure randomness and quantum-resistant security. It provides a REST API and web dashboard for quantum-backed entropy, NIST-standard post-quantum algorithms, a verifiable random function (VRF) oracle for blockchains, data protection tools, and threat intelligence. The stack runs as a single Docker image and is deployable to cloud or Hugging Face Spaces.

**Live demo:** [Hugging Face Spaces](https://huggingface.co/spaces/rocRevyAreGoals15/qcrypt-rng)

**Upgrade roadmap:** [docs/UPGRADE_ROADMAP.md](docs/UPGRADE_ROADMAP.md)

**AI / Cursor session prompt:** [docs/CURSOR_OPERATOR_PROMPT.md](docs/CURSOR_OPERATOR_PROMPT.md)

## What it does

- **Quantum randomness** — Random bytes, keys, UUIDs, passwords, and session tokens with configurable qubit counts (8/12/16) and batch generation.
- **Quantum VRF** — Verifiable random function with a one-time quantum seed, Keccak-256 commitment (Ethereum-compatible), and commit–reveal flow; supports Ethereum, Polygon, BSC, Avalanche, Fantom.
- **Post-quantum cryptography** — Complete NIST-standardized PQC suite:
  - **Signatures**: DILITHIUM2/3/5, FALCON512/1024, SPHINCS+-SHA2-128f (FIPS 204, 205)
  - **Key Exchange**: KYBER512/768/1024, NTRU-HPS, SABER (FIPS 203)
  - Full KEM workflow: generate keypair, encapsulate, decapsulate
- **Data protection** — AES-256-GCM, AES-128-GCM, AES-256-CBC (quantum or user-supplied keys); file encryption; HMAC sign/verify; quantum-salted hashing (SHA3, PBKDF2, BLAKE2b).
- **Blockchain security** — Quantum-safe vs classical wallet comparison, Shor-based attack simulation, chain comparison, demo mining, and oracle randomness (single and batch).
- **On-chain oracle fulfillment** — Real blockchain integration for oracle requests with commit-reveal on Ethereum, Polygon, BSC, Avalanche, and Fantom.
- **Threat intelligence** — Algorithm vulnerability scanning, oracle benchmarking, and qubit-to-break estimates.
- **Quantum hardware** — Abstraction layer for real QRNG devices (ID Quantique Quantis, QuintessenceLabs qStream) with entropy quality checks.
- **Operations** — Health checks, entropy quality and hardware status, monitoring metrics; optional rate limiting and API key auth.

## Quick start

**Prerequisites:** Python 3.8+, Node.js 18+ (for the dashboard), pip.

**Backend:**

```bash
git clone <repository-url>
cd qcrypt-rng
python -m venv .venv
source .venv/bin/activate   # Windows: .venv\Scripts\activate
pip install -r requirements.txt
python run_api.py
```

Use a **`.venv`** in the project root (not `venv/`). `scripts/start.py` also looks for `.venv/bin/python`.

API: http://localhost:8000 — Interactive docs: http://localhost:8000/docs

**Frontend:**

```bash
cd quantum-oracle-ui
npm install
npm run dev
```

Dashboard: **http://localhost:3040** by default (`quantum-oracle-ui/find-port.js` picks the next free port from 3040 upward so this project does not grab 3000). Auto-discovers API on ports 8000–8004, or set `NEXT_PUBLIC_API_BASE_URL`. See `quantum-oracle-ui/env.example`.

**Production:** See [docs/PRODUCTION.md](docs/PRODUCTION.md). For Docker: `docker-compose up -d` or Kubernetes via `./deploy.sh`.

**Hugging Face Spaces:** The root `Dockerfile` is built for Spaces (Nginx + FastAPI + Next.js on port 7860). Create a Docker Space, add the Space as a remote, and push `main`; use a [HF token](https://huggingface.co/settings/tokens) with write access when prompted. The app will be available at your Space URL after the build completes.

## Web dashboard

The dashboard has five sections and an in-app Docs link:

| Section | Capabilities |
|--------|----------------|
| Blockchain Security | Wallet creation, VRF proof generation and verification, supported chains |
| Data Protection | Encrypt/decrypt (text and file), sign/verify, hash, PQC key generation and sign/verify |
| Key and Entropy Tools | Random bytes, keys, UUIDs, passwords, tokens, batch generation, oracle requests |
| Threat Intelligence | Algorithm scanning, attack simulation, blockchain comparison, benchmarks |
| Network Status | Platform health, entropy quality, hardware status, oracle request lookup |

Each card includes an info popover; collapsible sections are used for dense workflows.

### Fulfillment Workflow

1. **Configure Chain:** `POST /oracle/fulfillment/configure-chain`
2. **Create Request:** `POST /oracle/fulfillment/request`
3. **Automatic Fulfillment:**
   - Generate quantum randomness
   - Create commitment (keccak256)
   - Submit commit transaction
   - Wait for confirmation
   - Submit reveal transaction
   - Mark as completed

### Fulfillment Status

### Security Notes

⚠️ **Private Key Security:**
- Never commit private keys to version control
- Use hardware wallets or KMS in production
- Store keys in environment variables or secure vaults
- Rotate keys regularly

### Testnet Deployment

For testing and development, deploy the oracle contracts to testnets:

**Supported Testnets:**
- Ethereum Sepolia (Chain ID: 11155111)
- Polygon Amoy (Chain ID: 80002)
- BSC Testnet (Chain ID: 97)
- Avalanche Fuji (Chain ID: 43113)
- Fantom Testnet (Chain ID: 4002)

**Deployment Guide:** See [docs/next-phase/TESTNET_DEPLOYMENT.md](docs/next-phase/TESTNET_DEPLOYMENT.md)

```bash
# Deploy to all testnets
cd quantum-oracle/contracts
npx hardhat run scripts/deploy-all-testnets.js --network sepolia

# Validate deployments
npx hardhat run scripts/validate-deployment.js --network sepolia
```

**Contract Addresses:** After deployment, update `.env` with contract addresses:
```bash
ORACLE_CONTRACT_SEPOLIA=0x...
ORACLE_CONTRACT_POLYGON_AMOY=0x...
# etc.
```
