Towards Remote Procedure Call Encryption by Default

Overview

RFC 9289, “Towards Remote Procedure Call Encryption by Default”, is a Proposed Standard document published in September 2022 by T. Myklebust, C. Lever. It updates RFC 5531. The canonical text is published by the RFC Editor.

Abstract

This document describes a mechanism that, through the use of opportunistic Transport Layer Security (TLS), enables encryption of Remote Procedure Call (RPC) transactions while they are in transit.
