This implements a generic SSL/TLS client which can establish a transparent
connection to a remote server speaking SSL/TLS. It's intended for testing
purposes only and provides only rudimentary interface functionality but
internally uses mostly all functionality of the OpenSSL B<ssl> library.
-=item B<s_server>
+=item L<B<s_server>|s_server(1)>
This implements a generic SSL/TLS server which accepts connections from remote
clients speaking SSL/TLS. It's intended for testing purposes only and provides
line oriented protocol for testing SSL functions and a simple HTTP response
facility to emulate an SSL/TLS-aware webserver.

+=head1 PASS PHRASE ARGUMENTS
+
+Several commands accept password arguments, typically using B<-passin>
+and B<-passout> for input and output passwords respectively. These allow
+the password to be obtained from a variety of sources. Both of these
+options take a single argument whose format is described below. If no
+password argument is given and a password is required then the user is
+prompted to enter one: this will typically be read from the current
+terminal with echoing turned off.
+
+=over 10
+
+=item B<pass:password>
+
+the actual password is B<password>. Since the password is visible
+to utilities (like 'ps' under Unix) this form should only be used
+where security is not important.
+
+=item B<env:var>
+
+obtain the password from the environment variable B<var>. Since
+the environment of other processes is visible on certain platforms
+(e.g. ps under certain Unix OSes) this option should be used with caution.
+
+=item B<file:pathname>
+
+the first line of B<pathname> is the password. If the same B<pathname>
+argument is supplied to B<-passin> and B<-passout> arguments then the first
+line will be used for the input password and the next line for the output
+password. B<pathname> need not refer to a regular file: it could for example
+refer to a device or named pipe.
+
+=item B<fd:number>
+
+read the password from the file descriptor B<number>. This can be used to
+send the data via a pipe for example.
+
+=item B<stdin>
+
+read the password from standard input.
