WEP Key Maker generates a hexadecimal WEP key from a pass phrase. IEEE 802.11b (aka Airport, Wi-Fi) uses a 104- or 40-bit (aka 128- and 64-bit) key to encode packets with WEP encryption. Third party devices typically use a hexadecimal key, which WEP Key Maker helps create. Generating such a key from a pass phrase makes it easy to create and reproduce a key without writing it down. The key can be copied from WEP Key Maker's dialog and pasted directly into Airport dialogs and third-party software. WEP Key Maker also creates keys of other lengths.
