When used on the computer with WZC (Wireless Zero Configuration), that program can save WPA-PSK password hash into the text file (press Export button on Misc Features | Wireless network page); EWSA can also dump password hashes from the local Registry itself (use Dump Windows WPAPSK hashes menu item). Please note that neither PSPR nor EWSA cannot extract hashes in the situation when wireless configuration is driven by 3rd party (vendor-supplied) utility instead of WZC.
