# Libaacs **libaacs** is a research project for a cross-platform open-source implementation of the AACS specification. ## Goals and features This research project provides, through an open-source library, a way to understand how the AACS works. This research project is mainly developed by an international team of developers from **Doom9**. Currently supported platforms are GNU/Linux, Windows, MacOS X. The main dependency is libgcrypt for all cryptographic functions. # Disclaimer This library is written for the purpose of playing Blu-ray movies. It is intended for software that want to support Blu-ray playback (such as VLC and MPlayer). We, the authors of this library, do not condone nor endorse piracy. This library is simply a tool for playback of Blu-ray movies. Like any tool, the use of this tool can also be abused. There are already numerous laws in different countries and juridictions all over the world that protect copyrighted material, such as Blu-ray movies. With that said, it would have been impossible for us to distribute this library with terms such as "you cannot use this library for piracy", because this would violate the Open Source Definition and the LGPL license. Instead, we present to everyone this disclaimer. As a reminder, here is also the disclaimer found at the beginning of any movie in relation to copyrights. ## ATTENTION International agreement and national laws protect copyrighted motion pictures, videotapes, and sound recordings. UNAUTHORIZED REPRODUCTION, EXHIBITION OR DISTRIBUTION OF COPYRIGHTED MOTION PICTURES CAN RESULT IN SEVERE CRIMINAL AND CIVIL PENALTIES UNDER THE LAWS OF YOUR COUNTRY. The International Criminal Police Organization - INTERPOL, has expressed its concern about motion picture and sound recording piracy to all of its member national police forces. (Resolution adopted at INTERPOL General Assembly, Stockholm, Sweden, September 8, 1977.) # Contribute To contribute, just compile the library and open merge requests on the repository: https://code.videolan.org/videolan/libaacs ## CoC The [VideoLAN Code of Conduct](https://wiki.videolan.org/CoC) applies to this project. ## Mailing list You can discuss about libaacs on the [libaacs-devel mailing list](https://mailman.videolan.org/listinfo/libaacs-devel) ## CLA There is no CLA. People will keep their copyright and their authorship rights, while adhering to the license. VideoLAN will only have the collective work rights. # FAQ ## Do you give the keys? We do not ship any encryption keys or cert, no. ## Do you provide binaries? No, we don't. You should compile this yourself. ## Do you implement HD-DVD AACS version? We do not, but patches are very welcome.
