Rockyou hcmask files

[royce]

I believe that they're derived from an expected runtime (based on a baseline cracking rate): The first number is a way to keep them sorted, and the second number is the number of seconds.

Code:

   836 rockyou-1-60.hcmask      <- 1 minute
  2968 rockyou-2-1800.hcmask    <- 30 minutes
  3971 rockyou-3-3600.hcmask    <- 1 hour
  7735 rockyou-4-43200.hcmask   <- 12 hours
 10613 rockyou-5-86400.hcmask   <- 24 hours
 17437 rockyou-6-864000.hcmask  <- 10 days
 25043 rockyou-7-2592000.hcmask <- 30 days

These were probably generated with PACK.
