Functions

func CheckKey

func CheckKey(k key.Key) error

CheckKey checks whether the given key is a valid AES-CBC-MAC key.

func GenerateKey

func GenerateKey(alg int) (key.Key, error)

GenerateKey generates a new Key with given algorithm for AES-CBC-MAC.

func KeyFrom

func KeyFrom(alg int, k []byte) (key.Key, error)

KeyFrom returns a Key with given algorithm and bytes for AES-CBC-MAC.

func New

func New(k key.Key) (key.MACer, error)

New creates a key.MACer for the given AES-CBC-MAC key.
