Router Password Kracker is a free software to recover the lost password of your Router. It can also be used to recover password from your internet Modem or Web sites which are protected by HTTP BASIC Authentication.
Generally Routers or Modems control their access by using HTTP BASIC authentication mechanism. In simple words, when you connect to your Modem/Router from the browser (typically http://192.168.1.1) you will be asked to enter username & password. If you ever forget this password then you will not be able to access your Router/Modem configuration. Even some websites use this BASIC Authentication to allow only certain users to access their site.
In these cases 'Router Password Kracker' can help you in quickly recovering your lost password. Also Penetration Testers and Forensic Investigators can find this tool very useful in cracking the Router/Modem/Website password.
