BitCracker – Open Source BitLocker Password Cracking Tool


BitCracker is the first open source BitLocker password cracking tool. BitLocker is a full-disk encryption feature available in recent Windows versions (Vista, 7, 8.1 and 10) Pro and Enterprise. BitCracker is a mono-GPU password cracking tool for memory units encrypted with the password authentication mode of BitLocker (see picture below).

Our attack has been tested on several memory units encrypted with BitLocker running on Windows 7, Window 8.1 and Windows 10 (both compatible and non-compatible mode). Here we present two implementations: CUDA and OpenCL.


For CUDA implementation, you need at least CUDA 7.5 and an NVIDIA GPU with minimum cc3.5 (i.e. Kepler arch)
