WirelessKeyDump

WirelessKeyDump is a command-line utility capable of listing all wireless network keys saved on your computer. The tool comes in handy if you have forgotten the passwords to your wireless network when you want to grant Internet access to a visiting friend, for example.

Doesn't require installation

There is no setup pack involved. Instead, the entire program's wrapped in a single executable file that you can save anywhere on the hard drive or copy to a USB flash drive to seamlessly launch WirelessKeyDump on any computer with as little effort as possible, without previous intsallations. No new entries are added to the system registry.

View your saved wireless passwords in a console window

All you have to do is call WirelessKeyDump's process from a console window. It automatically detects your saved wireless network passwords and shows them in a list in this panel, along with the security method applied.
There is no command integrated for dumping all this information to the Clipboard. However, you can select all text and press Enter to copy it to the Clipboard, then open a text editor, paste the content, and save it as a new file.

Old application with compatibility issues on newer Windows

The software utility hasn't received updates for a pretty long time, so you will likely experience compatibility issues with newer operating systems. For example, the tool failed in its attempt to list saved wireless password on Windows 10 in our tests, returning blank lines instead. For newer Windows versions, you can use WirelessKeyView, made by the same developer.
WirelessKeyDump was originally designed for Windows 2000, 2008, 7 and Vista, and it has separate executable files for 32-bit (x86) and 64-bit (x64) architecture types. For for 2008, 7 and Vista, you have to launch the tool with administrative privileges to be able to access the saved keys.
The downloaded package may be flagged as malware by certain antivirus engines but only because it can be used with malicious purposes (stealing someone's wireless passwords). Our tests have shown that WirelessKeyDump does not actually contain malware.
