From 6df87e64b78ae794ba49a5937b093e4c5dad4914 Mon Sep 17 00:00:00 2001
From: Peter Stuge <peter@stuge.se>
Date: Fri, 29 Jan 2010 23:06:31 +0100
Subject: [PATCH] Use LIBSSH2_HOSTKEY_HASH_SHA1 instead of _MD5 in examples and
 tests

MD5 support is optional and may not always be available, while SHA1 is both
required and recommended.
