How to crack passwords, and why you should
Page 2
Security Auditing passwords is a worthwhile venture, particularly in an environment that deals with sensitive information. Because systems encrypt passwords when they store them, you really can't properly judge the strength of a password unless you try to crack it. We suggest using a password-cracking tool such as John the Ripper. This tool works extremely well because it can crack MD5 passwords, which most systems currently use. In addition, it's much faster and more sophisticated than earlier password-cracking software such as Crack.

Once you've installed the tool, either from RPM or by compiling a copy yourself, you can set it to work. Keep in mind that John the Ripper uses a fair amount of CPU, but it will only use idle CPU time. However, copying the /etc/shadow file to a nonessential machine and running the tool on that, rather than a production machine, wouldn't be a bad idea either.
