beta 3.2.0

🚀 HyperDecode beta 3(v3.2.0) - Official Release

HyperDecode beta 3(v3.2.0) marks a major milestone in performance and investigative depth, focusing on crushing multi-layered obfuscation chains with native C speed.

🔥 What's New in beta 3(v3.2.0)

1. 🏎️ Performance Breakthrough (Core Optimization)

• Two-Phase XOR Brute-force: Implemented a smart Sampling Mechanism. Instead of performing 256 full transformations and allocations, the engine now performs lightweight scoring on a 256-byte stack-based sample. This reduces memory pressure and CPU cycles by up to 100x during XOR-intensive searches.
• O(1) Trigram Scoring: Replaced expensive string comparisons (strcmp) with a pre-indexed 3D lookup table. Million-candidate linguistic analysis now happens in single-digit milliseconds.
• Linguistic "Fast-Path": Added garbage-ratio detection to immediately discard high-entropy noise, focusing CPU power on meaningful decoding branches.

2. 🧠 Extreme Investigative Depth

• Search Depth Expansion: Increased default recursion limit to 6 layers (Max Depth = 6). It now effortlessly cracks complex chains like Binary -> Hex -> ROT13 -> Base64 -> XOR.
• Beam Search Refinement: Expanded default search width to 15 branches (Beam Width), ensuring no high-confidence results are pruned prematurely.
• Smart Priority Logic: Upgraded heuristics to give absolute precedence to Binary/Hex when the data matches pure 0/1 or hex patterns, eliminating "False Positives" from Base64 hijacking.

3. 🛠️ Bug Fixes & Refinements

• Critical Scoring Fix: Resolved a logic error where the engine occasionally scored the input buffer instead of the newly decoded candidate.
• Improved CLI Input: The CLI now automatically joins space-separated fragments (e.g., raw binary or hex blocks) into a single input stream without requiring manual quotes.
• Unified Versioning: Synchronized version 3.2.0 metadata across all modules (Qt Headers, Windows Resource Files, and Installer Scripts).

📊 Performance Benchmarks

• Triple-Layer Decode: < 100ms.
• 5-Layer Deep Search: < 500ms (down from 1.7s in v3.1).
• CPU Utilization: Optimized for 4+ threads in short, high-efficiency bursts.
• Memory Footprint: Stable under 32MB thanks to 32-bit hash-key deduplication.

📦 Getting Started

Download the stable installer HyperDecode_Setup.exe from the output directory and experience the most powerful heuristic decoder on the market.

beta 3.0

🛡️ HyperDecode v3.1.0 (Beta 3)

The Ultimate Multi-Layer Decoding Suite for Professionals

HyperDecode is a high-performance, intelligent de-obfuscation engine designed to peel back layers of encoding with surgical precision. Whether you are a security researcher, a CTF player, or a developer dealing with complex data formats, HyperDecode automates the "guesswork" and lets you focus on the data itself.

---

🔥 Why HyperDecode?

Ever spent hours manually running Base64 -> Hex -> XOR -> URL decode only to find out you missed a step? HyperDecode stops the madness.

• 🧠 "AI-Like" Heuristic Search: It doesn't just decode; it understands. Our engine analyzes data patterns to predict the next logical decoding step.
• ⚡ Performance First: Written in pure C and optimized for high-speed processing, it runs smoothly even on vintage hardware (i5-7200U tested).
• 🔋 Feather-Light: Consumes <32MB of RAM. Keep it open in the background without even noticing it's there.
• 🛠️ Unified Experience: Use the CLI for rapid scripting/piping or the Qt GUI for a deep-dive visual workspace.

✨ Key Features

1. Smart Pipeline Search

Drop your obfuscated string, and let the engine hunt for the original payload. It explores hundreds of transformation paths simultaneously, discarding dead ends and prioritizing high-confidence results.

2. The Recipe System

Create and save custom "Recipes"—predefined chains of transformations (e.g., Base64 -> Reverse -> Hex). Apply them to thousands of files instantly using the Batch Processor.

3. Professional CLI Tools

A fully colorized terminal interface with support for:

• Interactive Trace: See exactly how the engine derived the result.
• JSON Export: Integrated seamlessly into your existing automation pipelines.
• Piping: cat file.bin | hyperdecode --pipeline

4. Modern Compact GUI

A sleek, "Hacker-style" dark interface designed to provide a distraction-free environment. All tools (Decode, Encode, Pipeline, History, Recipes) are just one click away.

beta 2.0

Changelog

Beta 2.0

Auto Decoder Pro Beta 2.0 is the first Qt-focused beta centered on layered decoding, a redesigned desktop UI, and a release-ready Windows installer flow.

Highlights

• Added a new smart decoding pipeline:
  Input -> Fast Heuristic Engine -> AI Strategy Planner -> Multi-Pipeline Executor -> Scoring Engine -> Auto Retry + Mutation -> Best Result
• Replaced the previous simple search flow with a staged pipeline tuned for nested and ambiguous encoded strings.
• Switched the Qt desktop app to use the new pipeline in the Pipeline tab.
• Added a refreshed Qt Widgets UI with updated layout structure, clearer visual hierarchy, and theme-aware styling.
• Updated the installer configuration to package the current Qt desktop release build.

Added

• Smart pipeline API in the core engine for multi-stage decoding.
• Heuristic detection for structured content such as Binary, Hex, Base64, Morse, and URL-like inputs.
• Strategy planning that adjusts beam width and search depth based on input structure.
• Parallel candidate execution using GThreadPool.
• Retry and mutation logic for normalized input variants.
• Built-in layered decoding support for Binary, Hex, Base64, and Morse inside the pipeline flow.
• Qt installer packaging via installer/setup.iss for the current auto_decoder_qt.exe build.
• New English project README for the Beta 2.0 release.

Improved

• Candidate scoring now combines readability, confidence weighting, route penalties, and structured-decoding preference.
• Pipeline routing now prefers structured layers before exploratory transforms.
• Repeated low-confidence paths such as unnecessary Scramble chains are deprioritized.
• Readable text outputs now stop earlier instead of being over-processed by extra transforms.
• Layered inputs now get deeper search planning when the intermediate result still looks encoded.
• Theme loading now respects the saved preference on startup.
• Qt stylesheets were cleaned up to use valid Qt QSS instead of unsupported browser CSS rules.
• The desktop UI now uses a more consistent mono design system across dark and light themes.

Fixed

• Fixed startup behavior that always applied the dark theme before loading saved settings.
• Fixed invalid QSS behavior caused by unsupported properties such as transition, box-shadow, outline, opacity, @media, and browser-specific selectors.
• Fixed pipeline cases where binary-like inputs were incorrectly routed into Base64 at the first step.
• Fixed repeated-transform route selection that produced poor results on obvious structured input.
• Fixed several nested decoding cases where the pipeline stopped too early or chose the wrong exploratory branch.
• Fixed installer targeting so setup now packages the Qt release instead of the old non-Qt executable.
• Fixed a compile issue in pipeline.c related to candidate_last_step declaration order.

User-Facing Changes

• Pipeline tab now shows the Beta 2.0 staged pipeline flow.
• Improved route selection for strings encoded in multiple layers.
• Better output quality for structured chains such as Binary -> Base64 -> Hex.
• Updated application styling and font usage for a cleaner desktop experience.
• Installer output now targets the Qt desktop version directly.

Known Limitations

• The pipeline is still heuristic-driven and may need further tuning for intentionally misleading or adversarial inputs.
• Some deeply layered or mixed-format strings may still benefit from additional scoring trace visibility in the UI.
• Build and installer steps currently assume a Windows Qt + MinGW environment.

Upgrade Notes

• Rebuild the Qt application after stylesheet changes because QSS files are embedded through the Qt resource system.
• Recompile the installer after producing the Qt release build so the packaged runtime files stay in sync.
