Reaver DB weird
 

Hi,
Using reaver i always wanted to have ability to display passwords without re-cracking.
Reaver database is located here :/usr/local/etc/reaver/reaver.db
As it said
" The reaver.db SQLite database contains three tables:

"history" This table lists attack history, including percent complete and recovered WPA keys
"survey" This table is re-populated each time wash is run with detailed access point information
"status" This table is used to indicate the overall status of wash/reaver"


But in real there is only 1 table called "survey" and it doesn't contains passwords,only statistics.
Is it known problem?should I create new tables?if YES what're the names of columns?
