cRARk for 7-Zip 1.2a.
cRARk for 7-Zip purpose.
The primary goal of cRARk-7z is to.
recover (crack) your forgotten password on 7-Zip archives. 7-Zip versions 3.x-10.x are supported.
Please bear in mind you have quite no chance to crack unknown password (longer than 6-7 symbols) if you have no additional info about it. This is command-line utility for Win32/Win64, Linux.
7-Zip security overview At least from version 3.x, 7-Zip has been using a strong AES algorithm, which doesn't allow any attacks more effective than the brute force. Besides, the key derivation function is very similar to RAR one, and uses more than 130000 SHA-256 transformations and brute force rate on modern CPU is very low, only several hundreds of passwords per second. This carries inference that 7-Zip password encryption is one of the strongest between popular encryption systems in the context of brute force rate.
Features Advantages of cRARk for 7-Zip are.
One of the fastest 7-zip password recovery software, uses extremely optimized code.
Optimization for latest x86 instructions: AVX2, AVX, XOP, AES-NI for Intel Haswell and AMD Bulldozer processors.
Support of 7-Zip GPU password recovery on NVIDIA, AMD GPUs using CUDA and OpenCL, including NVIDIA Maxwell.
Multi-volume, self-extracting, encrypted header archives support.
Unique PCL language which is extremely efficient if user remembers any information about a forgotten password.
Portability (Windows, Linux are available.
0. What is the password for the achive.
There is no password to the crark-7z's executables and configuration files.
1. How to break and then to continue the search.
The program may be broken painlessly once the message "Testing XX-chars passwords. " is displayed, and then the search may be continued with - lXX option (both XX are equal.
2. How to resume search from the password XXX.
Sorry, no way. I's implemented in the PCL 3.0 used in Parallel Password Recovery.
3. The program has been searching for 10 days, but my password is not yet at hand.
Alas! It can't be helped. May be your password is too long, or the search set is wrong. Additional information on the password is necessary.
More questions and answers you'll find in the included documentation.
About CUDA/OpenCL support.
1. Which GPU is supported by cRARk-7z.
You need NVIDIA GPU card with CUDA support with compute capability 1.1 or higher; or AMD Radeon GPU card 5000/6000/7000 series; or Intel HD Graphics 4000 and higher with OpenCL support. Here is the list of such a cards with the exception of GeForce 8800 GTX/GTS, which has capability 1.0 You also need the latest drivers with CUDA support for NVIDIA cards: CUDA-capable drivers Notebook drives or latest drivers with OpenCL support for AMD Radeon cards: OpenCL-capable drivers.
2. How to run crark-7z on 64 bit OS.
On Win64 it runs fine. On Linux amd64 apart from CUDA drivers and CUDA shared libraries, you should install the ia32-libs package. Also, sometimes there are troubles with Catalyst drivers on 64-bit Linux. Here is the right way to install the latest driver.
3. I've got an error like "cudaThreadSynchronize failed: launch exceeded timeout" or "Display driver stopped and has recovered.
a. If you're using Windows Vista/7, please read the article. Or simply run the file from the cRARk's archive and reboot. b. Try to use the recommended -d option (look at the program output). c. Don't run crark-7z on primary graphics card, use separate GPUs for crark and monitor.
4. Program hangs after printing "Trying to compile XXXX kernel.
Please install the latest OpenCL drivers.
5. I've got any error in CUDA/OpenCL or CUDA/OpenCL is not working at all.
Please install the latest drivers (see above).. Don't overclock neither GPU nor CPU! If this not helps, please install the fresh copy of your operating system and install the drivers.
