oclHashcat v1.35 - atom - 03-22-2015



Download here: https://hashcat.net/oclhashcat/



This version 1.35 is about performance increase and bug fixes. Even if you did not face any errors with v1.33 we recommend upgrading.

Good thing is both oclHashcat v1.35 and oclHashcat v1.33 share the same driver dependancies. If you had a running v1.33 then v1.35 will work, too.

Most important changes:
  • Increased speed for SHA1 raw kernels, all AMD GPU
  • Increased speed for PDF kernel, all NVidia GPU
  • Increased speed for all multihash kernel using a different bitmap technique, all GPU
  • Fixed a race condition in multihash kernels
  • Fixed a buffer overflow that could lead to all kinds of segmentation fault or system freezing
  • Fixed a bug which caused clCreateBuffer() -61 Error even on single hashes

No more frankencat?


RE: oclHashcat v1.35 - shodan - 03-22-2015

Hm... if i use cudaHashcat64.exe -a 3 -m 20 -2 ?l?d -3 ?l?u hash.txt ?3?2?2?2?2?2?2
Quote:ATTENTION!
The wordlist or mask you are using is too small.
That mask is small?!
It need 4 hours to compute for 1000 hashes! (more hashes-more time and always one gpu)

And again i must use voodoo magic like --gpu-accel=2..6 or slow pipe Sad

Maybe be better if cudaHashcat64 can be "internally pipe" by itself for small mask? (without "external" pipe programm)


RE: oclHashcat v1.35 - epixoip - 03-22-2015

keyspace is only 52 + 36^6, that is incredibly small


RE: oclHashcat v1.35 - shodan - 03-22-2015

Ok 4 hours by gtx970 is small... but this make compute too long, if i use mask file with small and big keyspace inside.
User must calculated each mask and use many different ways to compute?! I dont think that is right way Sad
Maybe be right if hashcat can make all it internally?

I hope that is be fixed https://hashcat.net/trac/ticket/605 Sad

How i can understand, mask small or big?


RE: oclHashcat v1.35 - dylan - 03-22-2015

So I ran the exact same command on the same capture and same word list just as a comparison.

Code:
./oclHashcat64.bin -m 2500 -w 3 --gpu-temp-retain=60 --status ~/captures/netgear38.hccap ~/wordlists/SANITIZEDwpa2

Now I realize this is only against one hash type but the results were almost identical. Just providing info in case you wanted it. Let me know if you would like any other tests ran. But have updated to the new version and will update on anything useful. Thanks Atom!!!!! Great as always!
