FreeMe2 - open source WM-DRM removal tool
Hi.
After many hours of fighting with WM-DRM protection I decided to create new tool that would allow people to remove it from from files and streams. Of course FairUse4WM is great tool and it works nice but there are few reasons why have decided to create a new one: 1) FairUse4WM is closed source. Everytime MS releases new version of IBX people have to make binary patches or start from scratch. 2) FairUse4WM doesn't work with video streams since it wasn't intended to. Of course it is possible to record video stream and then undrm it but this is pointless when we are talking about tv channels 3) There is no platform independent tool for ms wm-drm. There is no point of running windoze every time you want to undrm some file or stream. FreeMe2 has reached beta stage. It CAN NOW be used by normal users. FreeMe2 should now handle all kinds of packets and successfully decrypt both wma and wmv files. It is even able to create correct file header and files paly fine (even in WMP). As you may guess FreeMe2 is based on famous FreeMe by Beale Screamer. Source code can be found here: http://sourceforge.net/projects/freeme2 Any help will be appreciated. Latest version available: FreeMe2 I will be updating this link. Last edited by sectroyer; 5th January 2008 at 13:23. |

I don't believe they will do so. All my code is based on information freely available on the net or obtained by clean room reverse engineering. It's not a crime to allow you playback of legally downloaded files on system other than windoze. Besides I don't live in US so DCMA doesn't bother me

If they will take the project down I will start bothering For now to access the source just use this:
svn co https://freeme2.svn.sourceforge.net/svnroot/freeme2 freeme2 I've just commited some initial support for wmv files as well for extracting IBX priv key from FairUse4WM's blackbox-keys.txt file. Last edited by sectroyer; 21st September 2007 at 16:10. |

I suggest every time you make a release, you also upload it with source to various file sharing/BitTorrent sites. Once it's out there there's basically no way they can take it down.

If you make it exclusive to un-DRMing Purchased Files...
Then I can see it probably staying... Because they can't lock what you own... By the way can it handle IBX Version 6000.7000 It seems people are having trouble with that little promiscuous file... Last edited by Ajax_Undone; 20th September 2007 at 05:43. |

FreeMe2 doesn't have any support for extracting IBX priv key. It contained some old code from freeme but It's commented since it doesn't work. At some point I may add an option for extracting IBX keys but not now and I need some more info about how FairUse4WM and mirakagi are able to do it. If you will be able to extract these keys in some way and put them in blackbox-keys.txt file than FreeMe2 will work with IBX Version 6000.7000 but then FairUse4WM will also work

Btw: I also get the error "Wrong size of SID!" on this: <DRM2WMV2> <KID>eDfaCCoaCEmyVR7yvocIDg==</KID> <SID>KbFvRF5E4XlNg5JgWNV2v+Z/zUZI</SID> <INFO></INFO> </DRM2WMV2> Edit: Decrypting works with DRM2WMV. The program won't exit at the end of the decryption process but the file is fine when I kill the process. Last edited by DreckSoft; 13th October 2007 at 21:42. |

Usually SID has length of 20 bytes whereas SIDs produced by new drmdbg have 21 bytes (at least the one you did post). I added new a line that shows you size of SID before warning about the wrong size of SID. If you will still get "Wrong size of SID" error please post the "Size of SID" printed by FreeMe2.

Okay program is now able to decrypt some wmv files (at least most of it) there are still some packets that I don't know how to handle. If someone has a better understanding of wmv/asf format please contact me. I based my findings on this doc: http://avifile.sourceforge.net/asf-1.0.htm. For those of you who don't like sources link to binary is in first post.

Maybe the ASF Specification on Microsoft's site has more information?

CLI app works great just freed up some files...
but the Console will confuse the Normals... Some one needs to make a GUI that is so simple that Brittany Spears can use it... lol Can anybody build one I don't have a lot of free time and it sure would be nice... Preferably one with a batch option... |

Just wanted to inform you that I have commited support for packets that use grouping and padding. In other words app should be able to handle all wma files and most of wmv files (some even play in WMP ). For testing please use mplayer since I don't think I generate correct headers. Link to binary in first post.
