title: Is OAuth irrelevant when HTTPS is used?
body: <p>I am designing a RESTful API which will always communicate over HTTPS. Is there any reason to use a scheme like OAuth when running over HTTPS? I am particularly interested whether or not aspects like HMAC-signed requests, nonces, and timestamps are useful when the entire communication is encrypted.</p>
  
  <p>It seems like any authentication scheme over HTTPS is sufficient but I just wanted to get a second opinion.</p>
