I found a better explanation for the 40-bit/64-bit and 104-bit/128-bit key business in an Avaya manual. Now I'm finally clear. An Encryption Key is composed of the secret key (entered by the user) and a 24-bit Initialization Vector (IV). Some products report an Encryption Key Size with the IV and some report a Key Size without the IV. Therefore, 64-bit encryption is also referred to as "40-bit" encryption (without the IV), 128-bit encryption is also referred to as "104-bit" encryption (without the IV), and 152-bit encryption is also referred to as "128-bit" encryption (without the IV). Great. So 128-bit can mean two different things. That's smart.

It's brief and not very techie. http://www.proxim.com/support/all/skyline/technotes/tn2001-08-03.html Basically it says they are the same. You should get 10 hex numbers with 64 bit WEP and 26 hex numbers with 128 bit WEP. I'd stick to the hex numbers and not the pass-phrase that is used to create it. It's a drag to type all of the numbers and such but it sounds like some folks have had problems with some WEP key generators. You should be all right to use the pass-phrase if you stick with the same wireless manufacturer I would imagine. I've had good luck with Linksys at least. _______________________________________________ Twin Cities Wireless Users Group Mailing List - Minneapolis/St. Paul, Minnesota http://www.tcwug.org tcwug-list at tcwug.org https://mailman.real-time.com/mailman/listinfo/tcwug-list _______________________________________________ Twin Cities Wireless Users Group Mailing List - Minneapolis/St. Paul, Minnesota http://www.tcwug.org tcwug-list at tcwug.org https://mailman.real-time.com/mailman/listinfo/tcwug-list
