NET Web APIUpdate I have put my another answer how to use JWT authentication for Web Api in here for anyone interested in JWT JWT Authentication for Asp. Net Web Api. We have managed to apply HMAC authentication to secure Web Api and it worked okay. Basically, HMAC authentication uses a secret key for each consumer which both consumer and server both know to hmac hash a message, HMAC2. Most of cases, hashed password of consumer is used as secret key. The message normally is built from data in the HTTP request, or even customized data which is added into HTTP header, message might include Timestamp time that request is sent UTC or GMT timeHTTP verb GET, POST, PUT, DELETE. URLUnder the hood, HMAC authentication would be Consumer sends a HTTP request to web server, after building the signature output of hmac hash, the template of HTTP request User Agent agent.

PMn. webapi. hmacapivaluesn. Please note that form data and query string should be in order, so the code on server get querystring and form data to build correct message. When HTTP request comes to server, an authentication action filter is implemented to parse the request to get information HTTP verb, timestamp, uri, form data and query string, then based on these to build signature use hmac hash with secret key hashed password on the server. The secret key is got from database with username on the request. Then server code compares the signature on the request with the signature built, if equal, authentication is passed, otherwise, it failed. The code to build signature private static string Compute.

So, how to prevent replay attack Add constraint for the timestamp, something like servertime X minutesseconds lt timestamp lt servertime X minutesseconds. And, cache the signature of request in memory use Memory. Cache, should keep in limit of time. If the next request comes with the same signature with previous request, it will be rejected.
