Abstract:
   This document is intended to inform the community about the impact of
   the deployment of the proposed Encrypted Client Hello (ECH) standard
   that encrypts Server Name Indication (SNI) and other data.  Data
   encapsulated by ECH (ie data included in the encrypted
   ClientHelloInner) is of legitimate interest to on-path security
   actors including those providing inline malware detection, parental
   controls, content filtering to prevent access to malware and other
   risky traffic, mandatory security controls etc.

   The document includes observations on current use cases for SNI data
   in a variety of contexts.  It highlights how the use of that data is
   important to the operators of both public and private networks and
   shows how the loss of access to SNI data will cause difficulties in
   the provision of a range of services to end-users, including the
   potential weakening of cybersecurity defences.  Some mitigations are
   identified that may be useful for inclusion by those considering the
   adoption of support for ECH in their software.
