Brute-force password cracker programs which claim GPU support include John the Ripper, ighashgpu, oclHashcat, and others. oclHashcat appears one of the more popular, but I am not sure which AMD/ATI GPUs it supports. (I have an ATI card.)

I've also used ighashgpu for MD5 cracking. It claims to be the worlds fastest multihash MD5 cracker for MD5. From comparisons i've read, i believe it to be true. The downside is that IghashGPU only supports SHA1, MD5 and MD4 hashes. Additionally, i odn't think its been updated for 2-3 years.

GPGPU computing is getting lots of attention these days. GPGPU computing simply means doing general calculations on graphic cards (GPUs) rather than CPUs. Traditionally, GPUs were used only for getting graphical output, rendering frames in games and other purposes related to graphics. Lately, people started realizing that GPUs are far more efficient at handling highly parallel tasks and that there should be a way to code for graphic cards. Though GPGPU computing is still at its infancy, a lot of progress has been made toward this direction. For example GPUs are used to speed up video conversion, video processing, doing scientific calculations, folding and password hash cracking.
But ighashgpu would take about just 17 minutes and 30 seconds maximum to crack the password hash. Also note that the password is already found in 2 minutes and 15 seconds. This means, my GPU would only take 17 minutes and 30 seconds max to crack ANY 7 character alphanumeric password.
ighashgpu is a single-purpose tool, whereas C&A does many things. My impression is that C&A is mostly used with rainbow tables (supplied elsewhere), whereas the author of the GPU tool is set on being the best.
Hi, For question A, the answer is a big no. Cracking a hash locally is not the same as doing that online. But why cracking a local hash is important is there are many ways to hack a web server to get access to the password hash table in the database that contains the user name and password hashes of millions of users. If that is accomplished, then a hacker can crack thousands of hashes locally. 2ff7e9595c
