IGHASHGPU

IGHASHGPU is a CMD application created to provide you with the means of recovering passwords from ATI and nVidia GPU hashes, even supporting salted hashes, which makes it handy for MSSQL, Oracle 11g, NTLM, and others.
Subsequent to the download process, you can decompress the archive and run the executable in a command prompt console. However, due to the lack of user interface, this tool is probably recommended for more experienced individuals.
The first run will display the available switches (commands), enabling you to choose which one to work with. The documentation material also provides several usage examples, including brute force attacks.
IGHASHGPU is meant to function with ATI RV 7X0 and 8X0, as well as nVidia CUDA video cards, providing a variable speed in accordance with the used GPU. It supports working with MD4, MD5, SHA1, MD5x2, MD5x2s, MySql5, IPD or DCC types of hashes.
Moreover, the program features a ‘-cpudontcare’ command that allows you to tell IGHASHGPU that it can use the maximum level of GPU, without any particular regard for CPU usage.
At the same time, you can set a temperature threshold for tracking your hardware (’-hm’), so you can make sure to desist any activity that causes your system to go over the permitted value (the default is 90 degrees Celsius).
An additional feature lets you set the block size so as to adjust the video response time and reduce any possible lags; if on the other hand, this is a characteristic that does not bother you in any particular way, you can input a higher value (as IGHASHGPU supports block sizes ranging between 16 and 23).
