From 40896f4a8f30bc6459fd7147aa43f4ccb4cb2146 Mon Sep 17 00:00:00 2001 From: Holger Freyther Date: Mon, 2 Apr 2007 15:59:35 +0000 Subject: packages/shasum: Add a sha256sum utility with little dependencies To avoid weird requirements add a sha256sum tool to OpenEmbedded directly. This will be part of the OE manifest and be guarded by the monotone OE trust chain. --- packages/shasum/files/mhash_sha256.h | 64 ++++++++++++++++++++++++++++++++++++ 1 file changed, 64 insertions(+) create mode 100644 packages/shasum/files/mhash_sha256.h (limited to 'packages/shasum/files/mhash_sha256.h') diff --git a/packages/shasum/files/mhash_sha256.h b/packages/shasum/files/mhash_sha256.h new file mode 100644 index 0000000000..46090c5f3e --- /dev/null +++ b/packages/shasum/files/mhash_sha256.h @@ -0,0 +1,64 @@ +/* sha.h + * + * The sha1 and sha256 hash functions. + */ + +/* nettle, low-level cryptographics library + * + * Copyright (C) 2001 Niels Möller + * + * The nettle library is free software; you can redistribute it and/or modify + * it under the terms of the GNU Lesser General Public License as published by + * the Free Software Foundation; either version 2.1 of the License, or (at your + * option) any later version. + * + * The nettle library is distributed in the hope that it will be useful, but + * WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY + * or FITNESS FOR A PARTICULAR PURPOSE.
