0phoi5 Posted July 25, 2016 Share Posted July 25, 2016 (edited) Hi all, Perhaps someone here has tried this and is able to advise? Say my password was a combination of lowercase letters of 8 digits. Using OCLHashCat, would it be faster to Brute Force using ... oclhashcat --hash-type [TYPE] file.hccat ?l?l?l?l?l?l?l?l ... or, would it be faster to use a wordlist, with all of the combinations of 8 lowercase letters in it ... oclhashcat --hash-type [TYPE] file.hccat wordlist.dic ... ? This is not taking in to account the time spent to generate the wordlist, or the size. Let's say that's already covered. *edit* I assume the wordlist would be slightly faster, based on there being one less step per password for the GPU to have to compute, but I guess what I'm trying to get at is whether it's a noticeable difference? Are we talking shaving only minutes or hours off, or could this potentially save days? Thank you. Edited July 25, 2016 by haze1434 Quote Link to comment Share on other sites More sharing options...
cooper Posted July 26, 2016 Share Posted July 26, 2016 The difference will be fractional. Generating a sequence in memory will be faster than a chunk of IO to acquire some structured data and then parsing that read data. Personally, I'd separate the two. Isn't there a wordlist generator (crunch or something?) that can do the generating and just pipes out the data which can feed into oclhashcat. Is probably easier to make continue from a certain point and/or distribute sections of the keyspace to multiple machines. Quote Link to comment Share on other sites More sharing options...
0phoi5 Posted July 26, 2016 Author Share Posted July 26, 2016 Thanks, good idea. It is Crunch, yes. I guess I was being lazy with asking this question, but I'm such a busy person! Next time I get a chance, I'll create a wordlist of all passwords between 0000 - 9999, run the following ... oclhashcat [...] ?d?d?d?d oclhashcat [...] numbers.txt crunch [...] | oclhascat [...] ... and let you guys know the results / which is fastest. Just need to find some spare time, which is easier typed than done! Quote Link to comment Share on other sites More sharing options...
cooper Posted July 26, 2016 Share Posted July 26, 2016 I actually scripted a sequence generator a while back: Quote Link to comment Share on other sites More sharing options...
