IGHASHGPU is an efficient and comprehensive command line GPU based hash cracking program that enables you to retrieve SHA1, MD5 and MD4 hashes by utilising ATI and nVidia GPUs.

It even works with salted hashes making it useful for MS-SQL, Oracle 11g, NTLM passwords and others than use salts.

IGHASHGPU is meant to function with ATI RV 7X0 and 8X0 cards, as well as any nVidia CUDA video cards, providing a variable speed in accordance with the users GPU. The program also 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).

It also has a feature that 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).

Hashes Supported for Cracking

As IGHASHGPU supports salted hashes it’s possible to use it for:

  • Plain MD4, MD5, SHA1.
  • NTLM
  • Domain Cached Credentials
  • Oracle 11g
  • MySQL5
  • vBulletin
  • Invision Power Board

Supported Cards/Requirements

  • Only currently supported ATI cards are:
    • HD RV7X0
    • RV830/870

  • Catalyst 9.9+ must be installed.
  • Only supported nVidia cards are the ones with CUDA support, i.e. G80+.
  • Systems with multiple GPUs supported.
