WEP Question
I am using a Dell True Mobile 1150 card. As far as I can tell it is Dell branded Lucent Gold Card. When I look at the back of the card it has "Encryption: 128RC4".
Looking at that I figured I could use a 128bit WEP key, but when I try to type in a seed for the key, it only takes ASCII 13 characters. Isn't that what I would expect for a 40bit key? I thought a 128bit key would take 26 characters. Am I out to luch here? |

Key sizes demystified
40-bit WEP (aka 64-bit WEP) is a 40 bit key plus a variable 24-bit IV which makes a 64-bit encryption key. The 40 bit key is equivalent to 5 ASCII characters or 10 hex digits.
104-bit WEP (aka 128-bit WEP) is a 104 bit key plus a variable 24-bit IV which makes a 128-bit encryption key. The 104 bit key is equivalent to 13 ASCII characters or 26 hex digits. |
