Edit Question
Title
Body
I recently read Jeff's blog post entitled Speed Hashing , where amongst other things he mentions that you can hash things really fast by harnessing the power of your GPU. I was wondering whether or not it was possible to harness the power of the GPU to hash things in Python (md5, sha-1 etc)? I'm interested in this for trying to see how fast I can brute-force things (not real world stuff, from old leaked data dumps). At the moment, I'm doing this sort of thing (simplified example): from itertools import product from hashlib import md5 hashes = ["some","hashes"] chars = [] for i in range(97,123): # a-z only chars.append(chr(i)) for i in range(1,6): # all combos of a-z, 1-5 chars for c in product(chars,repeat=i): s = ''.join(c) if md5(s).hexdigest() in hashes: print "Found",s But I was wondering whether there was a way to speed that up using the GPU? I'm guessing I'm going to need a module that would serially generate hashes like this - does anyone know of one?
