Password Decryptor Router is a small and free tool for recovering access data to device settings, WEP keys and WPA/WPA2 passwords from modem or router configuration files. The program allows you to recover all the most important data that is required to configure the router, and thus establish a connection to the Internet or home wireless network. This requires access to the router's configuration file, in which Router Password Decryptor automatically searches for relevant information and then decrypts it, thus enabling its reading.

The current version of the tool officially supports routers from such manufacturers as Cisco, Juniper, DLink and BSNL. In addition, it has a 'Smart Mode' mode, which allows you to try to recover data from other manufacturers' devices if you have their configuration files (only XML format is supported). Recovered information can be saved as a text file, HTML, CSV or XML file on the disk.
