Subject: [PATCH] crypto: testmgr: add test vectors for skein
Date:   Wed, 20 Jun 2018 19:57:14 +0900
Message-Id: <20180620105714.18359-1-j.m.torrespalma@gmail.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Adds test vectors specified in skein v1.3
specification. The main code is still in staging
directory, but this is required to eventually be
moved to the crypto directory.
