Ubisoft Denuvo dbdata.dll

This project provides a Rust implementation of a DLL (dbdata.dll) that emulates the Ubisoft Denuvo token interface. It is intended for research, reverse engineering, and interoperability purposes.

Usage

1. Build the DLL:

   cargo build --release
   

   The resulting DLL will be located in target/release/dbdata.dll.

2. Replace the file:

   Place the compiled dbdata.dll in the game files, replacing the real one.

3. Token Handling:

   • On first run, a token_req.txt file will be generated with the token request and appid of the game.
   • Place your token in a file named token.txt in the same directory.
   • The DLL will read the token from this file allowing denuvo to work properly.

Debug logs

• In debug builds, logs are written to a timestamped file (dbdata_<timestamp>.log).

Builds

Builds are available in the releases section of the repository. Nightly builds are also available in the actions section.
