I’m trying since few weeks to implement the unix crypt() - DES - function.
I started with the simple version of the algorithm (http://michael.dipperstein.com/crypt/crypt3.c). However I’ve poor performances : john is faster on a single CPU than on my GTX260 !
Now I’m “playing” with the Ultra Fast implementation (ufc-crypt) but I’ve some problem with memory allocation and various sync.
Did someone already have made such work ? Do you think, according to the first algorithm referenced above, the results I observed are normal or I made a mistake on the algorithm portage ? I mean : do you think such algorithm can be ported to -really- gain speed on GPU?
