oclHashCat-plus64 MD5(unix) cracking help

[TrAnn3l]

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.
