func Sign

func Sign(mac Hmac, body []byte) []byte

Sign takes an Hmac (with secret, algorithm, and expected header), and a body, and returns an HTTP header, similar to GitHub and GitLab HMACs for authenticating the body, via HTTP header envelope. see https://tools.ietf.org/html/draft-cavage-http-signatures-10 or a later revision for more details on the proposed RFC specification.
