WPA2 could i be doing this better?

[kiara]

10 characters not 10 digits..

yes their is, u are running a full brute force.. which take alot of time.
u can minimize ur time by generating a mask file for example
?u?d?d?d?d?d?d?d?d?d
?d?u?d?d?d?d?d?d?d?d
?d?d?u?d?d?d?d?d?d?d
etc...
+
wordlist + rules

to generate a mask file u can use PACK

if ur using The-Distribution-Which-Does-Not-Handle-OpenCL-Well (Kali) its already there
