Extension

Extend InterceptSuite functionality with custom Python extensions.

Overview​

InterceptSuite allows you to write custom extensions in Python 3 to interact with InterceptSuite APIs. Extensions provide powerful capabilities for packet data processing, analysis, and custom functionality integration.

Python Requirements​

Supported Python Versions​

  • Python 3.8 to Python 3.12
  • CPython Implementation - InterceptSuite uses CPython runtime
  • Package Support - Install any Python packages and add them to your scripts
  • System Installation Required - Extensions won't work unless Python is properly installed on your system

Installation Verification​

Before creating extensions, ensure Python is installed on your system:

  • Windows: Typically C:\Python312\ or similar
  • Linux: Usually /usr/bin/python3 or /usr/local/bin/python3
  • macOS: Often /Library/Frameworks/Python.framework/Versions/3.12/bin/python3

Python Configuration​

Initial Setup​

Before adding extensions, you must configure InterceptSuite to find your Python installation:

  1. Navigate to Extension Settings

    • Go to Extension tab → Settings tab

  2. Configure Python Path

    • Click the "Browse" button
    • Select the Python installation directory where your system has Python installed

  3. Example Paths:

    • Windows: C:\Python312\
    • Linux: /usr/bin
    • macOS: /Library/Frameworks/Python.framework/Versions/3.12/bin

  4. Confirmation

    • After selecting the directory, you'll see a green dot with "Python configuration found" text
    • This is a one-time setting - InterceptSuite will save the selected directory

Extension Management​

Adding Extensions​

  1. Navigate to Extensions

    • Go to Extension tab → Extensions tab

  2. Add New Extension

    • Click the "Add" button
    • Select your Python extension .py file from the file browser

  3. Extension Storage

    • InterceptSuite remembers the extension file location
    • Extensions are automatically loaded each time you open the app

Managing Extensions​

Extension Table​

  • View All Extensions - See all added extensions in the extension table
  • Select Extensions - Click on any extension to select it
  • Extension Status - Monitor loaded/unloaded status

Remove Extensions​

  • Select Extension - Choose the extension you want to remove
  • Click Remove - Click the "Remove" button
  • Permanent Removal - InterceptSuite removes it from configuration
  • No Auto-load - Extension will not be added when app opens again

Enable/Disable Extensions​

Unload Extensions (Temporary Disable)​

  • Checkbox Control - Click the tick box next to an extension
  • Unload Functionality - This unloads the extension temporarily
  • No Re-selection Needed - Extension remains in configuration
  • Quick Toggle - Allows disabling extension without removing

Benefits of Unloading​

  • Testing - Disable extensions during testing
  • Performance - Unload unused extensions to improve performance
  • Debugging - Isolate issues by temporarily disabling extensions

Extension Purpose​

Primary Use Cases​

Packet Data Processing:

  • Data Reading - Read and analyze packet data in real-time
  • Custom Processing - Apply custom logic to packet information
  • Data Transformation - Modify or transform packet data

Packet Data Dissection:

  • Protocol Analysis - Parse specific protocol data
  • Custom Protocols - Add support for proprietary protocols
  • Data Extraction - Extract specific information from packets

Development Resources​

Getting Started​

  • Extension APIs - Check the Extension API documentation for development details
  • Sample Code - Review example extensions for common use cases
  • Best Practices - Follow recommended patterns for extension development

API Documentation​

For detailed information on creating extensions, refer to the Extension API documentation which covers:

  • Available API endpoints
  • Event handling mechanisms
  • Data structures and formats
  • Integration patterns

Best Practices​

Extension Development​

  • Error Handling - Implement robust error handling in extensions
  • Performance - Optimize extensions to avoid impacting proxy performance
  • Testing - Test extensions thoroughly before production use

Extension Management​

  • Organization - Keep extension files organized in dedicated directories
  • Versioning - Maintain version control for extension files
  • Documentation - Document extension functionality and requirements

Security Considerations​

  • Code Review - Review extension code for security issues
  • Package Security - Be cautious with third-party Python packages
  • Access Control - Consider the permissions extensions may require
