Binary Inspect

A Python binary analysis tool for reverse engineering - detect formats, parse structures, inspect values.

Install

pip install binary-inspect

Or from source:

git clone https://github.com/daedalus/binary-inspect.git
cd binary-inspect
pip install -e ".[test]"

Usage

# Analyze a binary file (auto-detect format, inspect data, calculate entropy)
binary-inspect analyze file.bin

# Detect file format using magic bytes
binary-inspect detect file.bin

# Inspect data at specific offset
binary-inspect inspect file.bin 0x100

# Calculate entropy
binary-inspect entropy file.bin

# Find strings
binary-inspect strings file.bin

# Search for hex pattern
binary-inspect search file.bin -p "4D 5A"

# Display hex dump
binary-inspect hexview file.bin

# Parse with pattern
binary-inspect parse file.bin --pattern my_format.pybip --format json -o output.json

Features

• Magic Detection: Identify file format via header signatures (PE, ELF, PNG, ZIP, etc.)
• Data Inspector: Decode integers, floats, strings, GUIDs, timestamps at cursor
• Pattern Language: Define custom binary structures with DSL
• Entropy Analysis: Detect packed/encrypted sections
• Search: Find strings, integers, hex patterns
• Export: JSON, CSV, YAML output

API

from binary_inspect import (
    MagicDetector,
    DataInspector,
    EntropyAnalyzer,
    BinaryReader,
)

# Detect format
detector = MagicDetector()
match = detector.detect_one(data)
print(f"Format: {match.format_name}")

# Inspect at offset
inspector = DataInspector()
results = inspector.inspect(data, 0x100)
for r in results:
    print(f"{r['type']}: {r['value']}")

# Calculate entropy
analyzer = EntropyAnalyzer()
entropy = analyzer.shannon_entropy(data)
print(f"Entropy: {entropy:.2f}")

Development
