MD5 has known weaknesses and is discouraged in favor of SHA1 (see

+equipment requires the MD5 signature algorithm, we recommend that you
change the "ca.cnf", "server.cnf", and "client.cnf" files to specify
the use of SHA1 for the certificates. To do this, change the
-'default_md' entry in those files from 'md5' to 'sha1'.
