Combinator Attack and unique - Mem5 - 11-28-2017 Hi, When using Combinator attack (with two wordlists), hashcat does not unique duplicate words. I think it's useful, but it may exist a reason why developers did not implement that ? Thanks. RE: Combinator Attack and unique - royce - 11-29-2017 The assumption is that the user will deduplicate, if desired. RE: Combinator Attack and unique - Mem5 - 11-29-2017 From an algorithm perspective, would it be faster to sort & uniq on CPU or GPU, for huge files ? RE: Combinator Attack and unique - royce - 11-29-2017 CPU, I would think. Here's an alias that I stole from epixoip that works well on Linux: Code: bigsort() { LC_ALL=C sort --parallel=4 -S 4000M -T /path/to/fast/storage/ $*; } Adjust 'parallel' and '-S' option sizes to taste, based on your number of cores, RAM, etc. This assumes that you don't need to preserve order, and it's only one file. If you're managing a library of wordlists, for which order is significant (most likely words first), I've had good luck using rli/rli2 from hashcat-utils to remove duplicates among files. |
