CONCENTRATOR v3.2

Unified Hashcat Rule Processor — Extract, generate, and process hashcat password rules with GPU acceleration, Markov chain modeling, and functional minimization.

---

Features

• OpenCL GPU Acceleration — Batch rule validation offloaded to GPU for high throughput
• Three Processing Modes — Extraction, Combinatorial generation, and Markov-based generation
• Hashcat Rule Engine Simulation — Full CPU-side implementation of hashcat's rule operators
• Functional Minimization — Deduplicate rules that produce identical outputs
• Levenshtein Distance Filtering — Remove near-duplicate rules by edit distance
• Memory Safety — Monitors RAM/swap usage with configurable thresholds and disk-spill mode
• Multiple Output Formats — line (compact) or expanded (operator + args separated by spaces)
• Interactive & CLI Modes — Guided wizard or full argument-driven usage

---

Requirements

Python

Python 3.8+

Core (standard library — no install needed)

sys, os, re, argparse, math, itertools, multiprocessing, tempfile, random, datetime, threading, collections, typing

Optional (install for full functionality)

Package	Purpose	Install
pyopencl	GPU-accelerated rule validation	pip install pyopencl
numpy	Array operations for GPU buffers	pip install numpy
tqdm	Progress bars	pip install tqdm
psutil	RAM/swap monitoring	pip install psutil

All optional packages degrade gracefully — the tool runs on pure Python if none are installed.

---

Installation

git clone https://github.com/youruser/concentrator.git
cd concentrator
pip install pyopencl numpy tqdm psutil   # optional but recommended

---

Usage

Interactive Mode

Run without arguments to launch the guided wizard:

python concentrator.py

CLI Mode

python concentrator.py [OPTIONS] FILE_OR_DIRECTORY [FILE_OR_DIRECTORY ...]

One mode flag is required.

---

Modes

-e / --extract-rules — Extraction Mode

Extract the most frequent (or statistically weighted) rules from existing rule files.

# Extract top 5000 rules by frequency
python concentrator.py -e -t 5000 rules/

# Extract top 10000 rules sorted by Markov sequence probability
python concentrator.py -e -t 10000 -s rules/*.rule

Flag	Default	Description
-t, --top-rules	10000	Number of top rules to extract
-s, --statistical-sort	off	Sort by Markov probability instead of raw frequency

---

-g / --generate-combo — Combinatorial Mode

Generate rules by exhaustively combining the most common operators up to a target count.

# Generate 50k rules using operator combinations of length 2–4
python concentrator.py -g -n 50000 -l 2 4 hashcat/rules/

Flag	Default	Description
-n, --combo-target	100000	Target number of rules to generate
-l, --combo-length	1 3	Min and max operator-chain length

---

-gm / --generate-markov-rules — Markov Mode

Generate statistically probable rules using a Markov chain model trained on the input rule files.

# Generate 10k Markov rules of length 1–5
python concentrator.py -gm -gt 10000 -ml 1 5 hashcat/rules/

Flag	Default	Description
-gt, --generate-target	10000	Target number of rules to generate
-ml, --markov-length	1 3	Min and max rule length

---

-p / --process-rules — Processing Mode

Load, validate, deduplicate, and functionally minimize existing rule sets interactively.

# Process rules using disk mode to avoid RAM exhaustion
python concentrator.py -p -d rules/

# Process with Levenshtein distance filtering (max dist 3)
python concentrator.py -p -ld 3 rules/

Flag	Default	Description
-d, --use-disk	off	Spill to disk instead of keeping everything in RAM
-ld, --levenshtein-max-dist	2	Max edit distance for near-duplicate filtering

---

Global Options

Flag	Default	Description
-ob, --output-base-name	concentrator_output	Base filename for output (no extension)
-f, --output-format	line	Output format: line or expanded
-m, --max-length	31	Maximum rule token length to process
--temp-dir	system default	Directory to write temporary files
--in-memory	off	Process entirely in RAM (overrides disk mode)
--no-gpu	off	Disable OpenCL GPU acceleration

---

Output Formats

line — Standard hashcat rule format, one rule per line:

i3li4ei5y
li6po7io8e
D2i41o50
D1$9$6$0
o6g$1$5
D1i3hi4o

expanded — Each operator and its arguments separated by spaces, one rule per line:

i3l i4e i5y
l i6p o7i o8e
D2 i41 o50
D1 $9 $6 $0
o6g $1 $5
D1 i3h i4o

---

Input Files

Concentrator recursively scans directories up to 3 levels deep for files with these extensions:

.rule .rules .hr .hashcat .txt .lst

You can pass individual files, directories, or a mix of both.

---

Supported Hashcat Rule Operators

Concentrator validates and simulates the full hashcat rule operator set, including:

Category	Operators
Case	l u c C t T
Reverse / Duplicate	r d f p q
Rotation	{ }
Trim	[ ] D x O
Insert / Overwrite	i o ^ $
Substitute / Delete	s @ ! . ,
Extend	z Z y Y
Memory	M X 4 6
Arithmetic	+ - L R
Conditions / Length	< > _ = %
Leet / Replace	e E 3
Misc	: k K Q *

---

Examples

# Extract top 5000 rules (GPU off) from a glob
python concentrator.py -e -t 5000 --no-gpu rules/*.rule

# Generate 100k combinatorial rules, output in expanded format
python concentrator.py -g -n 100000 -l 1 3 -f expanded hashcat/rules/ -ob my_rules

# Markov generation with custom length range
python concentrator.py -gm -gt 20000 -ml 2 4 hashcat/rules/

# Process and minimize rules, writing temp files to /tmp/scratch
python concentrator.py -p -d --temp-dir /tmp/scratch rules/

# Interactive mode
python concentrator.py

---

Memory Considerations

• At startup, Concentrator prints current RAM and swap usage.
• If RAM usage exceeds 85%, a warning is raised and you are prompted before continuing.
• Use --use-disk / -d with -p mode to spill intermediate data to disk.
• Use --in-memory to force full in-RAM processing (fastest, but watch your available memory).
• Install psutil to enable memory monitoring.
