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 a 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 decode user passwords stored with the "7" algorithm, not the MD5 hash method employed by the "5" algorithm.
