        Title           : Completely Encrypting RTP Header Extensions and Contributing Sources

   While the Secure Real-time Transport Protocol (SRTP) provides
   confidentiality for the contents of a media packet, a significant
   amount of metadata is left unprotected, including RTP header
   extensions and contributing sources (CSRCs).  However, this data can
   be moderately sensitive in many applications.  While there have been
   previous attempts to protect this data, they have had limited
   deployment, due to complexity as well as technical limitations.

   This document updates RFC 3711, the SRTP specification, and defines
   Cryptex as a new mechanism that completely encrypts header extensions
   and CSRCs and uses simpler Session Description Protocol (SDP)
   signaling with the goal of facilitating deployment.
