WEP, or wired equivalent privacy, is a type of algorithmic security for networking devices such as routers and wireless access points. WEP communications encrypt traffic between a wireless router and a wireless device and require knowledge of the key to log into the system. WEP keys are often represented and entered as hexadecimal values, meaning values in a base-16 numeric system with information represented by both letters and numbers. This key is often derived from a security password that is entered in plain text. If you know the hexadecimal WEP key you can convert it back to its original ASCII, or American Standard Code for Information Interchange, text format.
Visit the dirtymonday.net website and click "Projects," then "WEP Key Converter." Type your hexadecimal key into the "Hex Key" box and your ASCII key will be displayed in the text box below it.
