I periodically export the mysql database with the encrypted user email passwords and run it through John the Ripper, and it finds a few every time. So it will all depend on how good the password is. Try it yourself with John http://www.openwall.com/passwords/unix.shtml; it's not difficult. If you use the big wordlists available at http://www.openwall.com/passwords/wordlists/, you will be amazed at how many passwords you can get. _______________________________________________ Full-Disclosure - We believe in it.
