np, i you check the -h option of hashcat like
cudaHashcat-plus64.exe -h
you will get many useful information Wink

i tested your command now..
i md5ed "zar2Hh" and saved it into a file in /md5.txt
and used your command :

Code:
./cudaHashcat-plus64.bin -m 0 -a 3 -i --increment-max=7 -o /cr3.txt /md5.txt --force

it must be cracked if your command is cheacking all combinations , yea ?
is it possible to test all combinations `atom` ? Sad

RE: oclHashCat-plus64 MD5(unix) cracking help - TrAnn3l - 05-01-2013

I tried the same hash you had, didn't crack it too, but then i tried it with a other command.
i cracked the hash, using

Code:
oclHashcat-plus64.exe -a 3 "hash.txt" ?a?a?a?a?a?a

well, i think there is a difference between using bruteforce only with -a 3 ,
and using it with the mask ?a?a?a?a?a?a (a stands for ?l?u?d?s). i don't know why, but maybe Atom can us say what is here going on.

RE: oclHashCat-plus64 MD5(unix) cracking help - epixoip - 05-01-2013

blind leading the blind.

if you don't specify a mask in mask mode, it uses the default built-in mask, which is almost never what you want.

if all you want to do is incrementally brute force all characters through length 7, you would simply use:

Code:
-a 3 -i ?a?a?a?a?a?a?a

RE: oclHashCat-plus64 MD5(unix) cracking help - TrAnn3l - 05-01-2013

And what is the default built-in mask?

RE: oclHashCat-plus64 MD5(unix) cracking help - epixoip - 05-01-2013

last, i knew, it was:

-1 ae10i2onrls938t45m67cdyhubkgpjvfwzAxEILORNSMTCDBqHYKUPGJFVWZXQ
-2 ae10i2onrls938t45m67cdyhubkgpjvfwzxq
-3 ae10i2onrls938t45m67cdyhubkgpjvfwzx._q!-*@
-4 1029384567

?1?2?2?2?2?2?2?3?3?3?3?4?4?4?4

but it may have changed

is it possible for my speed to crack this hash ? Sad

for crack a 4lenght pass..

Code:
./cudaHashcat-plus64.bin -m 0 -a 3 "/md5.txt" ?a?a?a?a?a?a?a?a?a?a?a?a -i --increment-min=1 --increment-max=12 --force

RE: oclHashCat-plus64 MD5(unix) cracking help - mastercracker - 05-02-2013

The MD5 hash of "zar2Hh" should be cracked in a short time. For the MD5(unix), it will take much longer (and don't forget to use -m 500 instead of -m 0). It would be easier if you use an adapted mask like ?l?l?l?d?u?l. However in a real case scenario, you don't know that so you go for the highest probabilities, meaning that you start with first letter upper or lower case, followed by a bunch of lowercase letter and maybe finishing by 1-4 numbers.

RE: oclHashCat-plus64 MD5(unix) cracking help - TrAnn3l - 05-02-2013

If you only want to crack one hash, you should use cudaHashcat-lite, that is much faster than normal cudaHashcat-plus, but you can only crack one hash at time. Also, if you want to crack a 4 length password, you don't need 12x ?a, you only need 4x ?a, and the increment things you typed are not really necessary.
The command to brute-force a 4 length password should be

Code:
./cudaHashcat-plus64.bin -m 0 -a 3 "/md5.txt" ?a?a?a?a

and if you want to crack all possible passwords up to 12 chars(which is really time-consuming with a not specified mask) the command should be

Code:
./cudaHashcat-plus64.bin -m 0 -a 3 "/md5.txt" ?a?a?a?a?a?a?a?a?a?a?a?a -i

And if you want to crack MD5(unix), you should use -m 500 instead of -m 0, just like mastercracker said.

RE: oclHashCat-plus64 MD5(unix) cracking help - sangiiin - 05-04-2013

can we use -m 500 in lite version ?
cause i cant see 500 option in hash mode list in --help .

anyway ... i understand , i cant crack it via one gpu because this md5 type give a heavy work to generate and check. so i must use multi gpus Or use good mask Big Grin
