Functions

func GetKDFValue

func GetKDFValue(key []byte, FC string, param ...[]byte) ([]byte, error)

This function implements the KDF defined in TS.33220 cluase B.2.0.

For P0-Pn, the ones that will be used directly as a string (e.g. "WLAN") should be type-casted by []byte(), and the ones originally in hex (e.g. "bb52e91c747a") should be converted by using hex.DecodeString().

For L0-Ln, use KDFLen() function to calculate them (e.g. KDFLen(P0)).
