-# TLS: ECH support in curl and libcurl
-
-## Summary
-
-**ECH** means **Encrypted Client Hello**, a TLS 1.3 extension which is
-currently the subject of an [IETF Draft][tlsesni]. (ECH was formerly known as
-ESNI).
-
-This file is intended to show the latest current state of ECH support
-in **curl** and **libcurl**.
-
-At end of August 2019, an [experimental fork of curl][niallorcurl], built
-using an [experimental fork of OpenSSL][sftcdopenssl], which in turn provided
-an implementation of ECH, was demonstrated interoperating with a server
-belonging to the [DEfO Project][defoproj].
-
-Further sections here describe
-
-- resources needed for building and demonstrating **curl** support
- for ECH,
-
-- progress to date,
-
-- TODO items, and
-
-- additional details of specific stages of the progress.
-
-## Resources needed
-
-To build and demonstrate ECH support in **curl** and/or **libcurl**,
-you will need
-
-- a TLS library, supported by **libcurl**, which implements ECH;
-
-- an edition of **curl** and/or **libcurl** which supports the ECH
- implementation of the chosen TLS library;
-
-- an environment for building and running **curl**, and at least
- building **OpenSSL**;
-
-- a server, supporting ECH, against which to run a demonstration
- and perhaps a specific target URL;
-
-- some instructions.
-
-The following set of resources is currently known to be available.
-
-| Set | Component | Location | Remarks |
-|:-----|:-------------|:------------------------------|:-------------------------------------------|
-| DEfO | TLS library | [sftcd/openssl][sftcdopenssl] | Tag *esni-2019-08-30* avoids bleeding edge |
-| | curl fork | [niallor/curl][niallorcurl] | Tag *esni-2019-08-30* likewise |
-| | instructions | [ESNI-README][niallorreadme] | |
-
-## Progress
-
-### PR 4011 (Jun 2019) expected in curl release 7.67.0 (Oct 2019)
-
-- Details [below](#pr-4011);
-
-- New configuration option: `--enable-ech`;
-
-- Build-time check for availability of resources needed for ECH
- support;
-
-- Pre-processor symbol `USE_ECH` for conditional compilation of
- ECH support code, subject to configuration option and
- availability of needed resources.
-
-## TODO
-
-- (next PR) Add libcurl options to set ECH parameters.
-
-- (next PR) Add curl tool command line options to set ECH parameters.
-
-- (WIP) Extend DoH functions so that published ECH parameters can be
- retrieved from DNS instead of being required as options.
-
-- (WIP) Work with OpenSSL community to finalize ECH API.
-
-- Track OpenSSL ECH API in libcurl
-
-- Identify and implement any changes needed for CMake.
-
-- Optimize build-time checking of available resources.
-
-- Encourage ECH support work on other TLS/SSL backends.
-
-## Additional detail
-
-### PR 4011
-
-**TLS: Provide ECH support framework for curl and libcurl**
-
-The proposed change provides a framework to facilitate work to implement ECH
-support in curl and libcurl. It is not intended either to provide ECH
-functionality or to favour any particular TLS-providing backend. Specifically,
-the change reserves a feature bit for ECH support (symbol
-`CURL_VERSION_ECH`), implements setting and reporting of this bit, includes
-dummy book-keeping for the symbol, adds a build-time configuration option
-(`--enable-ech`), provides an extendable check for resources available to
-provide ECH support, and defines a compiler pre-processor symbol (`USE_ECH`)
-accordingly.
-
-Proposed-by: @niallor (Niall O'Reilly)\
-Encouraged-by: @sftcd (Stephen Farrell)\
-See-also: [this message](https://curl.se/mail/lib-2019-05/0108.html)
-
-Limitations:
-- Book-keeping (symbols-in-versions) needs real release number, not 'DUMMY'.
-
-- Framework is incomplete, as it covers autoconf, but not CMake.
-
-- Check for available resources, although extendable, refers only to
- specific work in progress ([described
- here](https://github.com/sftcd/openssl/tree/master/esnistuff)) to
- implement ECH for OpenSSL, as this is the immediate motivation
- for the proposed change.
