 ## HTTP Signature Authentication
 
-HTTP Signature (currently a [IETF draft][http-signature-ietf-draft]) provides a way to achieve origin authentication and message integrity for HTTP messages. Similar to [Amazon's HTTP Signature scheme][amazon-http-signature], used by many of its services, it permits stateless, per-request authentication. [Elvio Toccalino][etoccalino] maintains the [djangorestframework-httpsignature][djangorestframework-httpsignature] (outdated) package which provides an easy to use HTTP Signature Authentication mechanism. You can use the updated fork version of [djangorestframework-httpsignature], which is [drf-httpsig].
