webserver

ESP32 Wi-Fi Penetration Tool

Webserver component

This component provides an UI for user to interact with the tool itself.

It is build on top of esp_http_server component that is described on official ESP-IDF reference page.

HTML sites are stored in RAM and are defined as a constant char array in pages/. Currently only one page is provided and it's updated dynamically usign AJAX calls from JavaScript client. Currently the Webserver is started by calling webserver_run() which registers all available endpoints and runs until ESP32 shuts down.

Endpoints

This webserver implements few enpoints that are used by JavaScript client.

• / displayes index.html page
• /status returns attack status in binary
• /reset tells the application to reset attack status to default READY state
• /ap-list scans near APs and displays them to table
• /run-attack sends configuration back to the application
• /capture.pcap provides PCAP formatted file for download
• /capture.hccapx provides HCCAPX formatted file for download

JavaScript client

Endpoints are called using AJAX calls from JavaScript provided on index.html page. It also parser reponses from webserver from binary to human readble form. It should do all additional computations that doesn't neccesarry have to happen on ESP32 to minimize its power consumption.

Utils

To make development of web client a bit easier, there is a script utils/convert_html_to_header_file.sh available that converts standard HTML file into header file and formats it to make it compilable.

Reference

Doxygen API reference available

Note: header files in pages/ are generated by script from utils/ folder, hence they don't contain docstring.
