IGHASHGPU – GPU Based Hash Cracking – SHA1, MD5 & MD4

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.

IGHASHGPU - GPU Based Hash Cracking - SHA1, MD5 & MD4

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

    -c             csdepa Charset definition (caps, smalls (default), digits, special, space, all)
    -u             [chars] User-defined characters
    -uh           [HEX] User-defined characters in HEX (2 chars each)
    -uhh         [HEX] User-defined characters in Unicode HEX (4 chars each)
    -uf            [filename] Load characters from file. Not used with Unicode.
    -sf            [password] Password to start attack from
    -m           [mask] Password mask
    -ms         [symbol] Mask symbol
    -salt        [hex] Append salt after password
    -asalt      [string] Append salt in ascii after password
    -usalt      [string] Append salt in unicode after password
    -ulsalt     [string] Same as above but unicode string firstly transformed to lower case
    -min       [value] Minimum length (default == 4), must be >= 4
    -max      [value] Maximum length (default == 6), must be <= 31 (not counting salt length)
    -h           [hash] Hash to attack (16 or 20 bytes in HEX)
    -t            [type] Type of hash to attack
    -devicemask:[N] Bit mask for GPUs usage, bit 0 == first GPU (default 0xFF, i.e. all GPUs). 
    -cpudontcare Tell ighashgpu that you want maximum from GPU and so don't care about CPU usage at all (and it means one CPU core at 100% per one GPU).
    -hm               [N] Set threshold temperature for hardware monitoring, default is 90C. You can disable monitoring by setting this value to zero.
    -blocksize     [N] Set block size, by default N = 23 which means 2^23 = 8388608 passwords offloaded to GPU in a single batch.
    By default charset processed as ANSI one. (i.e. WideCharToMultiByte(CP_ACP, ...) You can change this with: 
    -unicode  Use unicode
    -oem        Use oem encoding
    -codepage  [page] Convert charset to specific codepage (need to have it at system of course
