How long will it take to h@ck y3r Pa$$w0rd?

Ever been annoyed by those password policies that say “One digit, one uppercase, one lowercase” and then cap your password at, say 12 characters? Are those passwords secure these days, when cheap processing power is freely available ? A while ago I’ve stumbled upon an article where, among other info, some really interesting data was shared about how long it takes to crack standard crypto hashes used for password encryption in WLANs, web sites and operating systems. This prompted for a refresher in password security and brute-forcing performance. The numbers are worth sharing.
