When it comes to wireless networking, it is important to use a form of encryption called Wired Equivalent Privacy (WEP), so that only clients that know the “secret key” can connect to the wireless network.

While configuring a WiFi router we have to provide some WEP keys, the best is to generate random keys using our Linux, or any other Unix like OS.

$ dd if=/dev/random bs=1 count=13 2>/dev/null|xxd -ps

You will get something like:

3cafee64845c2617aa9d1b1411

This is a 104-bit key consist of 26 Hex digit, if you need a different key length just set count as follow:

• 40 bits: count=5
• 64 bits: count=8
• 104 bits: count=13
• 128 bits: count=16
• 152 bits: count=19
• 232 bits: count=29
• 256 bits: count=32
