Read notes about v0.90 at my blog first if you're curious why ATI version is so limited now.

Description

This software using ATI RV 7X0/8X0 and nVidia "CUDA" video cards to brute-force MD4, MD5 & SHA1 hashes. Speed depends on GPU,

ATI HD5870:

~3650M/s single MD5

~1360M/s single SHA1

ATI HD4770:

~1075M/s single MD5

~350M/s single SHA1

nVidia GTS250:

~570M single MD5

~175M single SHA1

As ighashgpu supports salted hashes it's possible to use it for:

Plain MD4, MD5, SHA1.

NTLM

Domain Cached Credentials

Oracle 11g

MySQL5

MSSQL

vBulletin

Invision Power Board

and more ...

Supported GPUs

以下是測試的畫面結果：

平均都是在幾分鐘或是幾秒內就解把密碼給解譯出來，算是另一種破解密碼的選擇。
