BitLocker Password Recovery
BitLocker Password Recovery Features:
- Several attacks can be configured and queued:
- brute-force attacks based on a charset and length selected:
- optional limit on a number of equal chars;
- dictionary attacks with modifications (several wordlists are included):
- password in reverse, capitalized, uppercased, lowercased;
- adjustable mixed-case mode;
- predefined or custom char replacements: Aa with 4, Oo with 0, Ii with !, etc.
- advanced keyboard layouts-aware recovery technique;
- mixed attacks for precise search range configuration;
- multi-position modifications to cover modern password policies;
- "Save passwords to a file" option to verify search settings or to generate a new wordlist, etc.
- Highly optimized code (SSE, AVX, AVX2) guarantees best performance.
- Utilizes NVIDIA and AMD Graphics processing units with a high-performance methods.
- Utilizes modern Intel HD Graphics GPUs.
- Supports up to 64 simultaneous processing threads (multi-CPU, multi-GPU).
- Audio, script or web address based post-search notification.
- Windows 7 - Windows 10 (including XTS-AES encryption).
BitLocker encrypted volume is protected with 256-bit long master key. Master key is saved several times encrypted with different access keys (e.g. Recovery Password based Key, TPM Key, Startup Key, User Password based Key). Access Keys are 128-256 bit long and there is no way to brute-force them directly in any realistic timeframe.
BitLocker Password allows you to search for User Password if it is set (default for BitLocker to Go). Password verification is extremely compute-intensive (about 2 millions of SHA256 calculations per password), so recovery speed is limited and strong CPU / GPU hardware is required to achieve good recovery speed.
You can use BitLocker Password to save information required for password recovery and use different PC to run actual search.
With BitLocker Password you can set several attacks including mixed attacks (combinations of dictionaries, brute and fixed parts) to limit search range and use all the information known about the original password.
What is the average speed?
The final password recovery speed is equal to CPUspeed + GPU(1)speed + ... + GPU(N)speed.
For example: Intel i3 + integrated HD 4400 GPU + AMD R9 270 = 16 + 7 + 275 = ~300 p/s.
|Intel® Core™2 Duo
T7500 @ 2.20GHz
|Intel® Core™ i3
2100 @ 3.10GHz
|Intel® Core™ i7
2600 @ 3.40GHz
|Intel® Core™ i3
4130 @ 3.40GHz
Intel HD and Iris Graphics: Intel integrated GPUs starting from HD Graphics 4000 can be used for password recovery acceleration. Intel GPU utilization is a unique feature of Thegrideon Software tools.

There are too many cards to list, but the main concept is simple: compute units (CUs) are the main building blocks of GPU calculation power. So card with 32 CUs is approximately twice faster than 16 CUs GPU of the same family and architecture.
AMD GPUs are very "password recovery friendly" and consistent despite architecture change from VLIW5 to VLIW4 and now to GCN.

|+ 142 (14/CU)||+ 275 (13/CU)||+ 448 (14/CU)|
Recovery speed with Kepler/Maxwell architecture cards (sm_35/sm_50 compute capabilities) is much better in per CU performance than with Fermi.
|NVIDIA GTX 470
(14 CUs, sm_20)
|NVIDIA GT 640
(just 2 CUs, Kepler, sm_35)
|+ 94 (7/CU)||+ 38 (19/CU)|
GPU performance is somewhat variable with number of factors including GPU/CPU combination and even driver version. Please contact us if your recovery speed is noticeable different from the data above.
Trial version allows you to setup and test run any password search for up to 15 min per set.
