Functions

func GenerateAuthenticatorResponse

func GenerateAuthenticatorResponse(Password []byte, NTResponse [24]byte, PeerChallenge [16]byte,
	AuthenticatorChallenge [16]byte, UserName []byte) [20]byte

RFC2759 section 8.7 page 9 return binary form of the result in the hash example password is utf-16 encode.

   Password = "clientPass" 密码的输入格式比较奇怪.utf16?
			   = 63 00 6C 00 69 00 65 00 6E 00
				 74 00 50 00 61 00 73 00 73 00

func MsCHAPV2GetSendAndRecvKey

func MsCHAPV2GetSendAndRecvKey(Password []byte, NTResponse [24]byte) (sendKey []byte, recvKey []byte)

http://www.ietf.org/rfc/rfc3079.txt

   Password = "clientPass" 密码的输入格式已经修正
			   = 63 00 6C 00 69 00 65 00 6E 00
