Technical Summary

   This draft describes the general problem of encryption of the Server
   Name Identification (SNI) parameter.  The proposed solutions hide a
   Hidden Service behind a Fronting Service, only disclosing the SNI of
   the Fronting Service to external observers.  The draft lists known
   attacks against SNI encryption, discusses the current "co-tenancy
   fronting" solution, and presents requirements for future TLS layer
   solutions.

Working Group Summary

Some working group members are not in favor of encrypting the SNI.  However,
the working group has consensus for continued work on the general topic of SNI encryption.

Document Quality

This document describes the problem and does not define a protocol. 
The document has been reviewed by the TLS working group.
