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. If the returned hash is `nil` make a call to `sslerr.Error()` to know what went wrong. Currently only `crypto.SHA512`, `crypto.SHA384`, `crypto.SHA256`, `crypto.SHA224`, `cryptoSHA1` and `crypto.MD5` are the only supported hashes. If an unsupported hash is provided the function will just return `nil` and no error from `sslerr` is given.

func NewWithEngine 

func NewWithEngine(e *engine.Engine, h func() hash.Hash, key []byte) hash.Hash

NewWithEngine behaves the same as New but it accepts a pointer to an `engine.Engine` to setup the engine to use during ctx setup.
