Re: WEP text-password to hex-key hashing formula



An airport base station allows you to enter shorter and/or longer-than- should-be passwords:

For example, an airport's 40-bit wep key could be set to (via airport utility) just the 3 letters "abc", and the equivalent wep key would be 0xFBACFD96BD... nothing to do with "abc", at first sight.

But if set to "abcde" (5 chars) instead, the equivalent wep key would be "0x6162636465"... as should be.

Hi,

I'm working on a project that is to interface with an apple airport.
This involves embedded hardware for which we've written drivers. We
would like to use the apple text-password to connect to the airport.
However, this means converting the text-password to a hex-key.

I am just guessing but I would suspect the hex value is simply the ascii value of each charcater. So 'Hello' would be:

48656c6c6f

Check out are the ascii man page, which indicates the values for each
character. This might also be useful:
