libressl/0009-Add-support-for-additional-GOST-curves.patch

From d0368ed4943958dfb98e6fc5c1a005ea9bddc49c Mon Sep 17 00:00:00 2001
From: jsing <>
Date: Fri, 5 Jun 2020 17:12:09 +0000
Subject: [PATCH 09/87] Add support for additional GOST curves.

These GOST curves are defined in RFC 7836 and draft-deremin-rfc4491-bis.
Add aliases for 256-bit GOST curves (see
draft-smyshlyaev-tls12-gost-suites) and rename the 512-bit curve ids to
follow names defined in tc26 OID registry.
