atom is insane! He managed to get some optimizations to tune up the speed of attacks under 8 chars to the "fullspeed".

As a conclusion oclhashcat-lite takes now about 45 seconds for the whole space of 6 chars on a 5970 at stock clock in NTLM!

He also finished his implementation of DCC and got a very nice performance improve of about 36% to 4608.1M/s from 3420M/s in oclhashcat v0.25.

To give that some extra spice he also finished increment mode support on salted hashes.


Got some new informations about the default attack of oclhashcat-lite:

Since the unique features of oclhashcat is the per position charsets it will automaticly use it in the default attack of the lite version. The masks are set like this:
?1 = "?u?l"
?2 = "?l?d@ "
mask = "?1?l?l?l?2?2?2?2?2"

This will produce output like this:
"Abcdx1 2@"
"Tommy 123"

Another new feature will be a "current"-line in the status output:

Status....: Running

Mask......: ?1?2?2?2?2?2?2?3

oclHashcat lite v0.01 = 10.1B on hd5970@770mhz


Atom decided to take the increment option as default. So the previous post has to be adjusted.

The default attack of oclhashcat-lite will adress 5-8 chars!


As you know atom is developing a new branch of oclhashcat called oclhashcat-lite. This version is dedicated to extreme easy handling, extreme optimizations of single-hash processing and it will be a research lab for atom.
The thought behind the lite version is that the user will soon get results by just entering the hash without taking care of masks, rules, gpu-loops or any of the advanced options that are available in the other versions. If the user then wants more options he will have the commitment learning to use the advanced versions.

One of the first questions that popped out of my mind as atom told me about the lite version was what will be the "predefined" attack mode? So basicly it will be a mask attack with followng features:
- 8 chars (cause that will hit approximitly 90%)
- lower chars
- digest chars
- some symbols

He constructed this because this will take approxmitly 1 hour one an ATI 5970.


atom has successfully enhanced the handling of salted hashes. It's now possible to run your attacks agains 32 byte salted hashes with no significant loss of speed!
