Cisco Password Decrypter

Summary

Cisco routers can be configured to store weak obfuscated passwords. This simple piece of JavaScript can be used to decode those passwords.

This is conversion from the original ciscocrack.c code by hobbit@avian.org. More information about the Cisco password algorithm can be found at http://www.insecure.org/sploits/cisco.passwords.html.

Note: This utility will only decrypt user passwords encyrpted with the "7" algorithm, not the MD5 method employed by the "5" algorithm.
