PowerShell script that decodes the .cfg file resulted from backing up the configuration of an Asus router.
It saves the entire decoded content of the .cfg file as [FileName]_Decoded.txt.

It also displays the following information if found in the config file:

• Admin username
• Admin password
• SSIDs (Wi-Fi names)
