I recently did a little research on this, and if the password was well chosen 
you will not find the password.  

An 8 character password, based on a 72 character set (26 lower case letters, 
26 uppercase letters, 10 digits, and 10 special characters) results in 72^8 
or 7.2x10^14 possible passwords.  My reference PC was only able to crack at 
1500c/s.  Doing the math reveals that 150,000 years would be required to 
crack all combinations, or 75,000 years on average.  For a 12 character 
password the result was 2,000,000,000,000 years.

If my math is wrong, please break it to me gently.
