cryptography - How does WEP wireless security work?
Jul 6, 2015 · For 64-bit WEP, the key is made with 24 bits from the IV and 40 bits from the WEP key, which results in a 5-letter ascii password or 10 hexadecimal characters. For 128-bit WEP, …
How to find a wep key inside a pcap file with only 2 IV?
Nov 4, 2017 · In order to break WEP you need to catch 2 packets with the same key and reused IVs. The number of packets in order to break the key depends on the length of the IV, but you …
Why it does not matter whether you type HEX or ASCII as WEP …
A 64-bit WEP key is usually entered as a string of 10 hexadecimal (base 16) characters (0-9 and A-F). Each character represents four bits, 10 digits of four bits each gives 40 bits; adding the …
