reavetard/src/db.coffee

CoffeeScript modules that provide AP rotation support and a host of data management and general usability enhancements for Reaver-WPS Cracker and its partner in crime, Wash-WPS Scanner

# Reavetard - Reaver WPS (+Wash) extension scripts
# db.coffee :: Swankified access to reaver.db and .wpc session files
#   Currently depends on sqlite3 bindings which may be difficult to install
#   on Backtrack (I had to make some manual changes to get the plugin built properly)
