🌐 PAXECT AEAD Hybrid Plugin — Authenticated Encryption for Every Platform

Status: v1.0.0 — Initial Public Release — October 22, 2025

" Deterministic, offline-first, and reproducible — built for secure data pipelines and NIS2-ready digital hygiene.”

🧩 Overview

The PAXECT AEAD Hybrid Plugin provides secure, deterministic, and streaming authenticated encryption for files, pipelines, and enterprise systems.

It combines AES-GCM (for x86 servers) and ChaCha20-Poly1305 (for ARM and mobile) in a unified hybrid implementation — delivering high performance, zero-dependency encryption that works identically across Linux, macOS, Windows, Android, and iOS.

Built for offline use, reproducible pipelines, and CI/CD automation, it powers everything from edge devices to enterprise cloud nodes.

Plug-and-play with zero dependencies and no vendor lock-in.

⚙️ One plugin. Two algorithms. Zero drift.

PAXECT Core Complete

Status: v1.0.0 — Initial Public Release — October 22, 2025

The curated PAXECT bundle: Core + AEAD Hybrid + Polyglot + SelfTune + Link — with 10 integrated demos, observability, and deterministic performance across OSes.

What it is: the official reference implementation of the PAXECT ecosystem — a verified, reproducible, cross-OS runtime that showcases the multi-OS bridge and in-freq multi-channel architecture in real workflows.

• Unified Ecosystem: Core + AEAD + SelfTune + Polyglot + Link in one deterministic bundle
• Reproducibility: bit-identical behavior across Linux, macOS, Windows (best-effort: BSD, mobile shells)
• Offline-first: zero telemetry, no network dependencies
• Enterprise-ready: 10 reproducible demo pipelines, audit trail, and metrics endpoints
• Zero-AI Runtime: SelfTune provides adaptive guardrails without ML or heuristics (no cloud)

Relationship

• PAXECT Core is a stand-alone OS-level deterministic bridge (plugin-capable).
• PAXECT Core Complete is the curated bundle that includes Core plus the official plugins and demo suite.
  Use Core when you want a minimal, plug-and-play bridge.
  Use Core Complete when you want the full experience (plugins + demos) out of the box.

Installation

Requirements

• Python 3.9 – 3.12 (recommended 3.11+)
• Works on Linux, macOS, Windows, FreeBSD, OpenBSD, Android (Termux), and iOS (Pyto).
• No external dependencies or internet connection required — fully offline-first runtime.

Optional Utilities

Some demos use these standard tools if available:

• bash (for demo_05_link_smoke.sh)
• dos2unix (for normalizing line endings)
• jq (for formatting JSON output)

Install

git clone https://github.com/PAXECT-Interface/paxect-core-complete.git
cd paxect-core-complete
python3 -m venv venv
source venv/bin/activate      # on Windows: venv\Scripts\activate
pip install -e .

Verify the deterministic core import:

python3 -c "import paxect_core; print('PAXECT Core OK')"

Then run any of the integrated demos from the demos/ folder to validate deterministic reproducibility.
