func New ¶

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

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.
