With these systems, you could get the key material and algorithm by looking at the software in the nav system. This was only possible because BMW made the mistake of using symmetric key algorithms in the 2nd generations of navigation systems (CIC). The original FSC generators were created by 'other' people by reverse-engineering they way the keys are calculated from something that is unique to the car (e.g. Not to belittle Jagaer's work, just to clarify what's what and who's who: Network not required.Īre you planning to develop some FSC generator for Route NAV users? Linux users must extract the file to a writeable directory (~/) and will need both QT5 and OpenSSL installed.

OSX must be v10.10 (Yosemite) and higher. The generator needs to download support files (Lookup.xml and RSAKeys.txt) in order for it to run correctly. Windows users must extract the file to a writeable directory (Desktop, Downloads, etc.), not run it from the zipped file. Hopefully if enough are gathered, some people will be able to create an FSC for their car, without having to pull any files.

I will not include or publish any car-specific information, but will add the FSC file date and RSA key to the RSAKeys.txt file. It appears that the key stored in the 'FSC' file pulled from the car is not necessarily unique to the car, but may be shared across multiple cars built within a short time window.Ĭode: FSC Date VIN Build Date Days DifferenceĢ00910211749 Thursday, Octo-1Ģ01001271515 Thursday, Janu-1Ģ01110310756 Wednesday, Novem-3Ģ01201111004 Thursday, Janu-1Ģ01210010521 Tuesday, Octo-1Ģ01210010703 Tuesday, Octo-1Ģ01210241654 Thursday, Octo-1Ģ01211081709ğriday, Novem-1Ģ01409161938 Wednesday, Septem-1If you would like to help out, and have pulled your FSC file, please send me a copy.In Linux and Windows, this file is stored in the same directory as the Key Generator. The Generator will download and use the most recent copy of the file. The RSAKeys.txt file keeps a copy all submitted RSA keys.The Key Generator will download and use the most recent copy of the BMW 'Lookup.xml' file for key generation parameters.(You can over-ride the detection setting, using the 'CIC/NBT' radio buttons). The Key Generator will auto-detect and accept either Base64 (Text) or binary FSC file inputs, as well as the file type (1B or NBT).This is (hopefully) a more user-friendly CIC/NBT FSC Key Generator for Windows, Linux and OSX based off of the work of the original FSC Key Generator and Intel123's certificate Patcher.
