hmac.digest()

hmac.digest([encoding])

Calculates the HMAC digest of all of the data passed using hmac.update(). The encoding can be 'hex', 'binary' or 'base64'. If encoding is provided a string is returned; otherwise a Buffer is returned;

The Hmac object can not be used again after hmac.digest() has been called. Multiple calls to hmac.digest() will result in an error being thrown.
