WEP - Wired Equivalent Privacy
(40bit)64bit 는 5자리
(104bit)128bit는 13자리 까지 입력을 해야한다.

64bit 가 8자리가 아니라 5자리가 된 이유는
24bit (3자리)의 IV(Initialization Vector)가 들어가기 때문이라는데 흐음..
IV가 먼지 까지 알아야 하려나... -_-
Standard 64-bit WEP uses a 40 bit key (also known as WEP-40), which isconcatenated with a 24-bit initialization vector (IV) to form the RC4 key.

WPA-PSK2 - Wi-Fi Protected Access Pre-shared key mode
8~63 자리
Pre-shared key mode (PSK, also known as Personal mode) is designed for home and small office networks that don't require the complexity of an 802.1X authentication server.[8] Each wireless network device encrypts the network traffic using a 256 bit key. This key may be entered either as a string of 64 hexadecimal digits, or as a passphrase of 8 to 63 printable ASCII characters.
