ASKey is a simple HEX to ASCII and vice versa converter for Mac OS X 10.3 or higher, including 10.4 Tiger for PowerPC and Intel. This software was especially made for converting WiFi WEP/WPA codes. Feel free to download and share - it's freeware!
Version 1.03: The conversion will be done just as you're typing. Also, the window is resizeable and the HEX code checks are better, now.
Mac OS X 10.3 or later
