=head1 DESCRIPTION
If the ciphersuite cannot request a client certificate (for example an
anonymous ciphersuite or PSK) this option has no effect.
+=item B<-nameopt option>
+
+option which determines how the subject or issuer names are displayed. The
+B<option> argument can be a single option or multiple options separated by
+commas. Alternatively the B<-nameopt> switch may be used more than once to
+set multiple options. See the L<x509(1)> manual page for details.

output.
+=item B<-client_sigalgs sigalglist>
+
+Signature algorithms to support for client certificate authentication
+(colon-separated list)
+
+=item B<-named_curve curve>
+
+Specifies the elliptic curve to use. NOTE: this is single curve, not a list.
+For a list of all possible curves, use:
+
+ $ openssl ecparam -list_curves
+
=item B<-cipher cipherlist>
This allows the cipher list used by the server to be modified. When
Protocol names are printable ASCII strings, for example "http/1.1" or
"spdy/3".
+=item B<-keylogfile path>
+
+Appends TLS secrets to the specified keylog file such that external programs
+(like Wireshark) can decrypt TLS connections.
+
+=item B<-max_early_data arg>
+
+Change the default maximum early data bytes that are specified for new sessions
+and any incoming early data (when used in conjunction with the B<-early_data>
+flag). The default value is approximately 16k. The argument must be an integer
+greater than or equal to 0.
+
+=item B<-early_data>
+
+Accept early data where possible.
