Hendrik-Blog: Rahasia : CUDA-Multiforcer – GPU Powered High Performance Multihash Brute Forcer

The Cryptohaze Multiforcer is a high performance multihash brute forcer with support for per-position character sets, and very good performance scaling when dealing with large hash lists. As an example, on a list of 10 hashes, the Cryptohaze Multiforcer achieves 390M steps per second on a GTX260/216SP@1.24ghz card. On a list of 1.4 million hashes with the same card, performance drops to 380M steps per second. This is the password stepping rate – not the search rate. The search rate is 380M * 1.4M passwords per second!
Platforms
The Cryptohaze Multiforcer supports Windows, Linux, and Mac OS X. An nVidia GPU with CUDA support (8000 series, 9000 series, GTX200 series, GTX400 series) is required for this to function. Additionally, a reasonably modern driver with CUDA support will be required. However, to see good rates, a fairly powerful GPU is required. GTX200 series cards are the lowest recommended cards.
Usage
The Multiforcer takes two files as inputs: the hash file, and the character set file. The hash file is very simple: One hash per line as follows:

The character set file is slightly more complex. For a single character set (the same character set applied to all positions), the character set file is very simple: Just the character set in a file, followed by a newline:
Single charset file (-c parameter)
