TLS warning collector

TLS warning collector is a tool to support the creation of an open dataset of TLS warnings and indicators in web browsers. It automatically downloads, installs and uninstalls browsers, and collects browser screenshots for comparison and analysis of TLS warnings.

Prerequisites

1. Windows 10 (download link for VM: https://developer.microsoft.com/en-us/windows/downloads/virtual-machines)
2. Chocolatey (link: https://chocolatey.org/docs/installation)
3. Python 3 (link: https://www.python.org/downloads/windows/)
4. Git (link: https://git-scm.com/download/win)

Installation

1. Install python3. On the installation screen, check the option to automatically set path (to use pip).
2. Clone the repository to your computer via git clone https://github.com/crocs-muni/tls-warning-collector.git
3. Download the browser driver -- follow the instructions in README.md in drivers folder.
4. Using Administrator cmd.exe, change directory to the tls-warning-collector-master and run pip3 install --quiet -r requirements.txt.

Configuration

You can change the configuration of the project in the config.yaml file. By commenting out the line with # you can choose which browsers and cases wont be in the dataset. If you dont want to run all of the browser versions then you can use "one-version", but you have to change the main.py file (all_versions = cfg.get("browsers")[browserID].get("versions") --> all_versions = cfg.get("browsers")[browserID].get("one-version")).

• Which "one-version" you want to run is easy to change -- just pick some of the supported versions and place it in the "[]" brackets in config.yaml file. E.g. one-version: [72.0.3626.121]

• Architecture x86

  For Chromium running on x86 OS you have to change the file location of the Application from ...\Program Files (x86)\ to ...\Program Files\ only (function - set_chromium_capabilities in browsers.py). !!!

Run

After that, go to the project location via Administrator command line and run the main.py script with this command:

$ pyhton main.py

Note: There may be a firewall settings popup during the first run as python wants to access the Internet. In older Firefox versions there can be a restart computer popup which you can postpone (Windows 7) or you have to restart the computer (Windows 10).
