Legit DLC Proxy Unlocker

🐨 DreamAPI

Welcome to the DreamAPI repository.

For user-friendly introduction or support, please check out the official forum thread. This document and repository are meant for application developers.

🚀 App architecture

Python

DreamAPI is written in Python 3. The python interpreter is bundled in distributable files. To run the project locally, you would need at least Python 3.8+

mitmproxy

At the core of DreamAPI lies mitmproxy - an interactive, SSL/TLS-capable intercepting proxy. It is written in python and supports python addons, which is where DreamAPI comes in. DreamAPI initializes mitmproxy and registers itself as an addon. This allows DreamAPI to intercept DLC requests made by various platforms to their services and modify responses.

SSL certificate

Virtually all web requests these days are encrypted with TLS. Hence, an SSL certificate needs to be installed in the Root Store, in order for mitmproxy to decrypt the encrypted traffic. DreamAPI tries to automatically install such a certificate when it doesn't find one installed. You can view the installed location by hitting Win+R, typing certmgr.msc, navigating to Certificates - Current User ➔ Trusted Root Certification Authorities ➔ Certificates and finding mitmproxy in this list.

Web proxy

Since DreamAPI works as a web proxy, an operating system needs to be configured with appropriate proxy settings for DreamAPI to work properly. DreamAPI does that automatically on every launch and shutdown of application. This is done by writing to the Computer\HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings key of the Windows registry. It is worth mentioning that DreamAPI intercepts requests only from specific domains, hence the irrelevant traffic is not tampered with.

GUI

For user convenience, DreamAPI provides a simple GUI built with TkInter with the help of infi.systray to manage the tray icon.

Packaging

To facilitate application distribution, python scripts and interpreter are bundled using PyInstaller. It produces both portable and installable executables of DreamAPI. Installable executables are then bundled into a setup file using Inno Setup.

The scripts directory has several scripts that automate from start to end the process of packaging and bundling the distributable files.

The scripts assume that there is a virtual environment located in the venv directory under the root of the project.

Running from source

There are many ways how you can run a python project from the source. Here is the flow that works for me:

1. Install pyenv.
2. Run the following commands from the project root in the windows command prompt (not powershell):

pyenv install 3.8.7
pyenv shell 3.8.7
pyenv exec python -m venv ./venv
scripts\install_python_requirements.bat
python src\main.py
