What is the encryption method used with wpa2?
WPA2 is capable of using several different encryption types. WPA2 (as opposed to WPA) introduced CCMP, a new AES-based encryption mode. In addition, WPA2 can operate in PSK, also known as Personal mode, which is designed for home and small office networks that don't require the complexity of an 802.1X authentication server. The wireless network device encrypts the network traffic using a 256 bit key. The key may be entered either as a string of 64 hexadecimal digits, or as a passphrase of 8 to 63 ASCII characters. If the ASCII characters are used, the 256 bit key is calculated by applying the PBKDF2 key derivation function to the passphrase and using the SSID as the "salt"or initialization parameter and 4096 iterations of HMAC-SHA1.Answers.com
