Functions

func Equal

func Equal(mac1, mac2 []byte) bool

Equal compares two MACs for equality without leaking timing information.

func New

func New(h func() hash.Hash, key []byte) hash.Hash

New returns a new HMAC hash using the given hash.Hash type and key. New functions like sha256.New from crypto/sha256 can be used as h. h must return a new Hash every time it is called. Note that unlike other hash implementations in the standard library, the returned Hash does not implement encoding.BinaryMarshaler or encoding.BinaryUnmarshaler.
