PolycryptZero (p0) - Hash Decryption Tool

A hash cracking tool with GUI that supports multiple attack methods and hash algorithms. It includes support for a probabilistic mode which uses a GPT2 style autoregressive transformer model, trained for password generation and prediction.

✨ Features

• 🔐 Attack Modes: Wordlist, Brute-force, Rule-based, AI-powered probabilistic, Rainbow tables
• 🔒 Hash Support: MD5, SHA family, bcrypt, BLAKE2, and 20+ other algorithms
• 🤖 AI Integration: Custom GPT2 ML model for intelligent password generation and completion
• 🌈 Rainbow Tables: Bloom filter optimized storage with SQLite backend
• 🎨 Modern GUI: Dark theme interface with real-time progress tracking

Probablistic mode uses an autoregressive transformer model, similar to GPT-2, for sequential data analysis:

Key Features: (check src/train.py)

• Transformer Architecture: Employs multi-layer, multi-head self-attention mechanisms.
• Generative: Predicts subsequent elements in a sequence.
• Configurable: Core parameters like layers, attention heads, and embedding dimensions can be adjusted.

📦 Installation

Option 1: Executable (Windows)

Download the latest release from Releases and run PolycryptZero.exe - no Python required.

Option 2: Python Source

git clone https://github.com/bitArtisan1/p0-Decryption-Tool.git
cd p0-Decryption-Tool
pip install -r requirements.txt
python src/main.py

📋 Requirements

• Python: 3.11+
• Dependencies: customtkinter, pycryptodome, numpy, onnxruntime, transformers

🚀 Usage

1. Enter target hash
2. Select hash algorithm
3. Choose attack mode
4. Configure parameters (wordlist, character set, etc.)
5. Start attack

For Wordlist and Rule-Based modes, you need a passwords wordlist to test against (e.g: rockyou.txt):

curl -LO https://github.com/brannondorsey/naive-hashcat/releases/download/data/rockyou.txt

For probablistic mode, choose the provided onnx_model-output directory

⚔️ Attack Modes

• 📚 Wordlist: Dictionary attack using password lists
• 💪 Brute-force: Try all possible combinations
• ⚙️ Rule-based: Apply transformations to wordlist (capitalization, leet speak, etc.)
• 🧠 Probabilistic: AI model generates likely passwords, use provided onnx_model_output path
• 🌈 Rainbow Table: Precomputed hash lookups

TODO

• Improve model architecture for better pattern matching
• Add linux support release
• Add CUDA GPU support for probablistic attack mode
