Use GPU to crack wpa/wpa2

Test environment:
Win7 SP1 X64/Nvidia 630 M
After grasping the handbag under Kali, you can crack it in Windows.
I used aircrack-ng to crack it, which is about key/s.
So I just want to try GPU cracking.
1. Convert the cap package to the hccap package of oclhashcat under Kali.
Aircrack-ng test. cap-J test
Generate test. hccap
2. Use oclhashcat-plus to crack

CudaHashcat-plus64-m 2500 test. hccap wordlist. diccudaHashcat-plus64 is because I am Nvidia graphics card, 64-bit, if it is ATI will start with ocl-m 2500 represents the wap/wap2 cracking mode Session. name... : CudaHashcat-plusStatus ......... : RunningInput.

The speed is about 7000, which is much faster than the CPU.
