UXSP — Universal Exchange Security Protocol

UXSP (Universal Exchange Security Protocol) is an enterprise-grade, hybrid post-quantum security framework. It is designed from the ground up to protect your web APIs, file streams, messaging layers, and live media against classical eavesdroppers and the upcoming threat of quantum computers.

💡 What is UXSP?

In standard web applications, data sent over the internet relies on traditional encryption (like RSA or ECC). However, upcoming quantum computers will soon be powerful enough to break this traditional encryption, exposing sensitive user records, financial transactions, and private messages.

UXSP solves this problem today by providing "Hybrid Post-Quantum Security":

1. Double-Layer Armor: It combines trusted classical encryption (AES-256-GCM + X25519/Ed25519) with modern NIST-standardized Post-Quantum Cryptography algorithms (ML-KEM FIPS 203 and ML-DSA FIPS 204).
2. Zero-Complexity for Developers: Instead of writing hundreds of lines of complex cryptographic setup, UXSP provides beautiful, high-level APIs that allow developers to secure entire applications, web endpoints, multi-gigabyte file transfers, and even WebRTC video streams with just 1 line of code.

✨ Features Overview

UXSP comes packed with capabilities to handle any data transfer scenario securely:

• Send Any Format: Whether you are sending plain text, structured JSON, raw binary, large files, documents (PDF, Word), images, photos, audio, voice memos, archives (Zip), locations, or contacts, UXSP provides dedicated classes for all data types. It automatically serializes, chunks, encrypts, and packages the data.
• Live Video Calls: Negotiate high-performance AES-GCM secure WebRTC sessions for real-time video calls with a single line of code.
• Live Voice Calls: Establish encrypted audio streams with configurable codecs and sample rates for highly secure voice communication.
• Live CCTV Integration: Securely connect and stream data from live CCTV cameras, protecting sensitive monitoring feeds from interception.
• Web Framework Middlewares: Drop-in middlewares for FastAPI, Django, and Flask. They automatically decrypt incoming requests, verify identities, and encrypt outbound responses, replacing the need for traditional CSRF tokens.
• Durable Replay Protection (NonceStores): Out-of-the-box support for Memory, Redis, and Postgres-backed NonceStores (both synchronous and asynchronous) to ensure intercepted messages can never be replayed by an attacker.
• Frontend Interoperability: A companion NPM package allows your web frontend to encrypt data directly in the browser before it even hits the network.

(For detailed implementations, tutorials, and code examples of these features, please refer to the docs/ directory).

⚙️ Installation & Setup

UXSP is highly modular. You only need to install the dependencies required for your specific framework and storage needs.

System Prerequisites (liboqs)

UXSP utilizes liboqs for C-native Post-Quantum Cryptography acceleration. You must install the required build tools for your platform:

• Ubuntu / Debian / Mint:

  sudo apt update && sudo apt install -y build-essential cmake ninja-build libssl-dev git
  

• Fedora / RHEL / CentOS:

  sudo dnf groupinstall -y "Development Tools" && sudo dnf install -y cmake ninja-build openssl-devel git
  

• macOS:

  brew install cmake ninja openssl@3
  

• Windows: Requires Visual Studio Build Tools (C++), CMake, and Git. (Note: Windows support is experimental and falls back to msvcrt for certain operations).

(If liboqs fails to compile on your system, UXSP will automatically fall back to its built-in pure Python Post-Quantum Cryptography implementations, ensuring it always runs).

🚀 How to Access the Project (Documentation)

For detailed step-by-step developer tutorials, architectural explanations, and complete code examples, please head to the docs/ directory.

The documentation is written to be perfectly clear, even if you are a new programmer without deep domain knowledge in cryptography or networking.

Start by reading the Index (docs/index.md), which will guide you through:

• High-level and Low-level APIs
• Synchronous vs. Asynchronous Usage
• Live Video, Audio, and CCTV Streaming
• Django, Flask, and FastAPI Middleware configurations
• Replay Protection with NonceStores
• The UXSP Command Line Interface (CLI)
