From 0c5a66fd2d137897419a0b8340a15f2965d89380 Mon Sep 17 00:00:00 2001 From: David Disseldorp <ddiss@suse.de> Date: Fri, 5 Apr 2013 16:13:36 +0200 Subject: [PATCH 07/12] md5: use in-tree MD5 rather than libcrypto Currently libcrypto (openssl) is linked purely for md5 calculation utilities. Use the tiny in tree library instead, and do away with the libcrypto dependency.
