=head1 NAME
SSL - OpenSSL SSL/TLS library
=head1 SYNOPSIS
+See the individual manual pages for details.
+
=head1 DESCRIPTION
The OpenSSL B<ssl> library implements the Secure Sockets Layer (SSL v2/v3) and
Transport Layer Security (TLS v1) protocols. It provides a rich API which is
documented here.
-At first the library must be initialized; see
-L<SSL_library_init(3)|SSL_library_init(3)>.
-
Then an B<SSL_CTX> object is created as a framework to establish
-TLS/SSL enabled connections (see L<SSL_CTX_new(3)|SSL_CTX_new(3)>).
+TLS/SSL enabled connections (see L<SSL_CTX_new(3)>).
Various options regarding certificates, algorithms etc. can be set
in this object.
When a network connection has been created, it can be assigned to an
B<SSL> object. After the B<SSL> object has been created using
-L<SSL_new(3)|SSL_new(3)>, L<SSL_set_fd(3)|SSL_set_fd(3)> or
-L<SSL_set_bio(3)|SSL_set_bio(3)> can be used to associate the network
+L<SSL_new(3)>, L<SSL_set_fd(3)> or
+L<SSL_set_bio(3)> can be used to associate the network
connection with the object.
Then the TLS/SSL handshake is performed using

=item SSL *B<SSL_dup>(SSL *ssl);
+SSL_dup() allows applications to configure an SSL handle for use
+in multiple SSL connections, and then duplicate it prior to initiating
+each connection with the duplicated handle.
+Use of SSL_dup() avoids the need to repeat the configuration of the
+handles for each connection.
+This is used internally by L<BIO_s_accept(3)> to construct
+per-connection SSL handles after L<accept(2)>.
+
+For SSL_dup() to work, the connection MUST be in its initial state
+and MUST NOT have not yet have started the SSL handshake.
+For connections that are not in their initial state SSL_dup() just
+increments an internal reference count and returns the I<same>
+handle.
+It may be possible to use L<SSL_clear(3)> to recycle an SSL handle
+that is not in its initial state for re-use, but this is best
+avoided.
+Instead, save and restore the session, if desired, and construct a
+fresh handle for each connection.
