The number of combinations equals to the multiplication of the number of items in each part.

Password candidates are generated as a composition of the parts (chars, words) and all possible combinations have to be processed. It is easy to see from examples that additional details (known or assumed) can used to shorten search time significantly.Д«asic combinatorics knowledge is handy for a search complexity assessment. Dictionary attack with capitalization and replacement option 'Aa->4' is a way faster alternative in this case. Mixed attack: 1 char 'A.Z' + 1 char '0.9' + 6 char 'a.z' is a lot faster. Example: password 'P4ssword' can be discovered in a very slow manner with 8 char long brute-force search. There are multiple ways to search for the same password, time requirements are different as well. Password search is a guessing game - your password can be as simple as '1234' for example, but alphabetic-only search is not going to be successful in any timeframe when digits-based search expected to be quite fast. It is easy to see that password search is the only real option in such cases and our goal is to provide you with highly optimized tools with very flexible search patterns setup.

Passwords are usually salted (random values are added) in order to block any preimage attacks or generation of rainbow tables. Hashing algorithms are commonly applied multiple times making known cryptanalysis research methods inapplicable.

In the the run_test.sh script there are several attack examples using the encrypted images provided in this repo: Use -s option only if BitCracker returns several false positives. Altough this check is empirically verified and it works with the images of this repo encrypted with Windows 7, 8.1 and 10, we can't guarantee that it doesn't lead to false negatives. Note: In case of false positives you can use the -s option, that is a more restrictive check on the correctness of the final result. t, -passthread Set the number of password per thread threads d, -dictionary Path to dictionary or alphabet file s, -strict Strict check (use only in case of false positives) f, -hashfile Path to your input hash file (HashExtractor output) Then you can use the output hash file to run the BitCracker attack. The extracted hash is fully compatible with the John The Ripper format (see next Section). i, -image Path of memory unit encrypted with BitLocker The executables are stored in the build directory.Д«efore starting the attack, you need to run bitcracker_hash to extract the hash from the encrypted memory unit. Use the build.sh script to build 3 executables: Here we present two implementations: CUDA and OpenCL.ДЇor CUDA implementation, you need at least CUDA 7.5 and an NVIDIA GPU with minimum cc3.5 (i.e. 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).
