    Change the default digest for pki/ssl_setup to sha256
    
    The default digest was `default`, which meant that the digest was the
    openssl default of sha1. The default setting should be a SHA2
    algorithm since this meets current security standards.
    
    This is for security hardening.

    The `default_message_digest` configuration options now default to
    `sha256` instead of `default`.
