You can also use attack mode 6 (dict + mask) with oclhashcat-plus and use the salts as a dictionary.

RE: md5(salt.pass) troubles and tricks - atom - 08-06-2012

new plus will support generic md5(salt.pass)

RE: md5(salt.pass) troubles and tricks - d0znpp - 08-08-2012

Thx... and you can guide the timing of the release of new version?
I would also like to become a beta tester, if possible

RE: md5(salt.pass) troubles and tricks - atom - 08-09-2012

Become a beta-tester is OK, all you need to do is to send me a test-plan. This ensures you are not trying to become a beta-tester so you have the new algorithms earlier. Otherwise just wait for the new release.

And what about ordering?
Test case
Code:
md5(str_repeat('a',16))=='23ca472302f49b3ea5592b146a312da0'
Testing
Code:
./oclHashcat-lite64.bin -m 0 23ca472302f49b3ea5592b146a312da0 -1 abcde ?1?1?1?1?1?1?1?1?1?1?1?1?1?1?1?1 --pw-min 16 -s 120544432500
false (pass not found)

./oclHashcat-lite64.bin -m 0 23ca472302f49b3ea5592b146a312da0 -1 abcde ?1?1?1?1?1?1?1?1?1?1?1?1?1?1?1?1 --pw-min 16 -s 120544432499
true (pass found)

What about wiki? It is wrong as i see:

will latest version markov kicked in and changed everything. you can try --markov-disable. the wiki needs to be updated, that is true

and what is order with the --markov-disable option?

Because aaaaaaaaaaaaaaaa is not first in order, but 625 AND (!!!) 152587890255 . Why?!

Great news, thanks atom! Does this include the sha families as well? I've been needing a sha256(salt.pass) for a while so this would be awesome whenever it comes.

RE: md5(salt.pass) troubles and tricks - atom - 09-05-2012

yes Smile
