## 🚀 Project Overview

**pqbit** is a modular Python library for building secure, decentralized, and post-quantum digital infrastructure. It combines cryptographic primitives, mesh networking, traffic cloaking, and offline identity generation into a unified toolkit designed for resilience and autonomy.

Built for researchers, engineers, and privacy advocates, `pqbit` empowers users to:

- 🔐 Generate and verify post-quantum keys and signatures using Kyber, Dilithium, and Falcon
- 🕸️ Deploy adaptive WireGuard mesh networks with entropy-based routing and namespace isolation
- 🛰️ Broadcast encrypted discovery messages across cloaked overlays using Obfs4 and PySocks
- 🔑 Create offline wallets with SHA3-512 fingerprints and Dilithium-signed seed phrases
- 📊 Monitor traffic entropy, latency, and peer trust in real time via PyShark and Scapy

Whether you're prototyping quantum-safe VPNs, auditing peer identities, or building sovereign mesh systems, `pqbit` gives you full control over every cryptographic and network layer — with zero reliance on centralized infrastructure.

## 🔐 Security

**Dilithium5** is a lattice-based digital signature scheme selected by [NIST](https://csrc.nist.gov/projects/post-quantum-cryptography) for post-quantum cryptography. It offers strong resistance against quantum attacks while remaining efficient for real-world use.

**SHA3-512** is part of the Keccak family, providing robust hashing with high collision resistance and integrity guarantees.
Together, they ensure that `pqbit` remains secure even in a future with quantum computing.
