Option which determines how the subject or issuer names are displayed. The
-B<val> argument can be a single option or multiple options separated by
+I<val> 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.
=item B<-id_prefix> I<val>
-Generate SSL/TLS session IDs prefixed by B<val>. This is mostly useful
+Generate SSL/TLS session IDs prefixed by I<val>. This is mostly useful
for testing any SSL/TLS code (eg. proxies) that wish to deal with multiple
servers, when each of which might be generating a unique range of session
IDs (eg. with a certain prefix).
=item B<-status_timeout> I<int>
-Sets the timeout for OCSP response to B<int> seconds.
+Sets the timeout for OCSP response to I<int> seconds.
=item B<-status_url> I<val>
=item B<-psk_identity> I<val>
-Expect the client to send PSK identity B<val> when using a PSK
+Expect the client to send PSK identity I<val> when using a PSK
cipher suite, and warn if they do not. By default, the expected PSK
identity is the string "Client_identity".
=item B<-psk_hint> I<val>
-Use the PSK identity hint B<val> when using a PSK cipher suite.
+Use the PSK identity hint I<val> when using a PSK cipher suite.
=item B<-psk> I<val>
-Use the PSK key B<val> when using a PSK cipher suite. The key is
+Use the PSK key I<val> when using a PSK cipher suite. The key is
given as a hexadecimal number without leading 0x, for example -psk
1a2b3c4d.
This option must be provided in order to use a PSK cipher.
=item B<-psk_session> I<file>
-Use the pem encoded SSL_SESSION data stored in B<file> as the basis of a PSK.
+Use the pem encoded SSL_SESSION data stored in I<file> as the basis of a PSK.
Note that this will only work if TLSv1.3 is negotiated.
=item B<-listen>
These flags enable the Enable the Application-Layer Protocol Negotiation
or Next Protocol Negotiation (NPN) extension, respectively. ALPN is the
IETF standard and replaces NPN.
-The B<val> list is a comma-separated list of supported protocol
+The I<val> list is a comma-separated list of supported protocol
names. The list should contain the most desirable protocols first.
Protocol names are printable ASCII strings, for example "http/1.1" or
"spdy/3".
=item B<-engine> I<val>
-Specifying an engine (by its unique id string in B<val>) will cause B<s_server>
+Specifying an engine (by its unique id string in I<val>) will cause B<s_server>
to attempt to obtain a functional reference to the specified engine,
thus initialising it if needed. The engine will then be set as the default
for all available algorithms.
