Cain & Able
While I’m on the subject of tools, another good tool to look at is Cain & Able (http://www.oxid.it/projects.html) which is a somewhat grey/blackhat type tool. It has a specific section for brute-forcing Cisco PIX-MD5 and IOS-MD5 password as well as a section where you can type in a password and it will give you all sorts of hashes including IOS and PIX MD5 hashes. For example:
Text to hash: cisco
Type Hash

It can also do cute thinks like ARP Poisioning, SSH and HTTPS Man-in-the-middle, and sniffing/recording VoIP traffic. Overall, a neat utility for demonstrating why you need Cisco Integrated Security Features!
