iTunes backup crack too slow
#9
I'm not sure what's the problem. All numbers match perfectly. I ran this on my rx480 which is the closest I have matching you GPU.

It's 10,000,000 iterations of PBKDF2-HMAC-SHA256. So let's benchmark PBKDF2-HMAC-SHA256 first:

Quote:$ ./hashcat -b -m 10900 -w 3 --machine
# version: v5.1.0-720-g4653447d
# option: --workload-profile=3
1:10900:1236:300:96.02:644529

Note the default iteration count of raw PBKDF2 based algorithms is 1000. So we have (644529 * 1000) / 10000000 = 64,45. Now benchmark of itunes 10:

Quote:$ ./hashcat -m 14800 -b
...
Speed.#1.........:       65 H/s (56.82ms) @ Accel:256 Loops:64 Thr:64 Vec:1

It couldn't be more exact. The benchmark speed also matches the real cracking performance:

Quote:$ ./hashcat -m 14800 hash.txt -a 3 ?l?l?l?l?l -u 64 -n 256 --force 
...
Speed.#1.........:       65 H/s (43.98ms) @ Accel:256 Loops:64 Thr:64 Vec:1
