Welcome to oclHashcat-lite v0.10.
Download it here: http://hashcat.net/oclhashcat-lite/
Code: This release is a big step forward. We have added both, many major and many minor features.
Per-position markov-chains, aka markov-attack/incremental-attack/charset-files
The markov-attack is a statistically based brute-force like attack, but instead of specifying a charset or a mask, we specify a file. This file is once generated by ourself in a previous step. It contains statistical informations which are made out an automated analysis of a given dictionary.
It can fully replace Brute-Force since it covers the full keyspace.
In Brute-Force Attack (or in Mask Attack) we can limit the keyspace by setting a smaller charset in order to reduce the attack-time. In Markov Attack we have something similar, the "threshold". All you do is to specify a number. The higher the number, the higher the threshold to add a new link between two characters on the two-level table on which the markov-attack bases on.
This background is not so important, just remember that the lower the value, the smaller the keyspace and thus the faster the attack is.

Use .ptx ad .llvmir intermediate kernels
The kernels are distributed in an "intermediate" format (aka IL). It cant be reversed to original C code but still its not a binary format that can be used for execution.
The JIT (just-in-time) compilers from both OpenCL and CUDA, which ship with the driver, compile the final byte-code out of the IL. This takes a few seconds per kernel but once its done the byte-code is cached (CUDA does it automatically, OpenCL not but we add a function to do the same as CUDA does).
This has some nice advantages:
Not 32/64 bit specific
Less HDD space
Smaller .7z
Less problems with driver specific problems as we often see with Catalyst
There is no more need to release a new oclHashcat-* in case a new driver optimization has been added. oclHashcat-* caches driver specific. If it recognizes a driver change it will rebuild thge byte-code from the IL, but using the new JIT from the new driver resulting in driver specific optimized byte-code.
Retaining GPU temperature
When I started with oclHashcat-* Hardware mangement support, some people asked me for add support for fan-speed. For a long time I was not interessted in adding fan-speed code to oclHashcat-* since this is the job for the driver or some specialized controling software.
I did not change my mind completly on this, but still we have added some fan-speed controlling code. The new parameters are:
Code:
--gpu-temp-disable Disable temperature and fanspeed readings and triggers
--gpu-temp-abort=NUM Abort session if GPU temperature reaches NUM degrees celsius
--gpu-temp-retain=NUM Try to retain GPU temperature at NUM degrees celsius (AMD only)
So what this thing is doing is: If the temperature configured with the new --gpu-temp-retain parameter is reached, it starts to increase the fan-speed by 1 percent each second. Thats all.
If you imagine a scenario what this means you will come to the conclusion that this feature also enables you to enfore your GPU running always to a very specific temperature.
Some notes:
--gpu-temp-disable you can completly disable all the temperature stuff.
--gpu-temp-retain currently only works for AMD.
--gpu-temp-abort parameter is just the renamed version of the old --gpu-watchdog.
Both parameters accept the 0 value which disables only this specific feature. This means you can step back to the old behavior by specifying --gpu-temp-retain 0.
The default for --gpu-temp-abort is still 90c.
The default for --gpu-temp-retain is 80c.
Built-in benchmarking mode
Code:
* Benchmark:
-b, --benchmark Run benchmark
--benchmark-mode Benchmark-mode, see references below
Nothing much to explain here I think, but some notes to the benchmark mode:
As long as you do not set the --benchmark-mode you can modify all the configuration parameters you always use. Something like -d, -n, --gpu-accel or --runtime.
With --runtime you can specify the duration how long each test lasts.
If you add -m you can limit to a specific hash-type. If you do not set it, it will iterate through all hash-types.
All unneccessary parallel threads like hardware monitor, restore-support and outfile-watch are disabled. Also the quiet mode is enabled.
On NVidia, the hashes based on SHA256, SHA512 and DES are limited to -n 32, otherwise the driver throws the error cuStreamSynchronize() 702.

Welcome to oclHashcat-lite v0.9.
Message from Atom (Hashcat-Lite Developer + Bruteforce Guru)
Code: Hello Hashcat-Users,
I am proud to announce version 0.09 of the oclHashcat-lite series.
Download it here: http://hashcat.net/oclhashcat-lite/
The highlights of this release are:
Support for AMD GCN cards (hd7xxx series)
I already wrote some more detailed informations about the integration here: http://hashcat.net/forum/thread-817.html
This card is a true DES killer. I wrote some more detailed informations about this topic here: http://hashcat.net/forum/thread-846.html
Added the LM Algorithm
After so many people requested this algorithm in the feature request section I decided to add it even I had not interesst in it.
However, it turned out it was a good investment of time. I realized how many pentester still have need for it.
See here for discussion: http://hashcat.net/forum/thread-167.html
Vectorized datatype kernels for sm_21 NVidia architecture
This a massive improvement for low- and mid-ranged NVidia GPUs.
The gtx560Ti @ MD5, for example, increased by 23% (1252 Mhash/s -> 1660 Mhash/s).
This improvement can be seen on nearly all algorithms for this architecture.
MD4 based algorithm tuning
To make it short: I found a way to reverse another step in MD4.
Especially the NTLM and DCC algorithm benefit from this code change.
The hd6990 @ NTLM broke the 20000 Mhash/s mark on stock clocks. Average increase is around + 9% (19100 Mhash/s -> 20864 Mhash/s).
Updated EULA
This goes back to a discussion we had HD Moore from Rapid7.
The updated EULA is a lot more relaxed for professional pentesters than before.
See changelog for more details.
Fixed some major issues
On thing that many user complained about in oclHashcat-lite 0.08 was its "instability" and problems with session restore.
This popped in because of a default-settings change in oclHashcat-lite v0.07. It has been set back to oclHashcat-lite v0.06 default.
Discussion can be found here: http://hashcat.net/forum/thread-681.html
Harmonization with oclHashcat-plus
The --help page, the --outfile-format and the -m parameter values, in case of an overlap, are now equal to oclHashcat-plus v0.08.
It will help to avoid confusion, thats why I am planning to do the same change on CPU hashcat in the next version.
