=head1 NAME
SSL - OpenSSL SSL/TLS library
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
L<SSL_accept(3)|SSL_accept(3)> or L<SSL_connect(3)|SSL_connect(3)>
L<SSL_accept(3)> or L<SSL_connect(3)>
respectively.
L<SSL_read(3)|SSL_read(3)> and L<SSL_write(3)|SSL_write(3)> are used
to read and write data on the TLS/SSL connection.
L<SSL_shutdown(3)|SSL_shutdown(3)> can be used to shut down the
L<SSL_read(3)> and L<SSL_write(3)> are
used to read and write data on the TLS/SSL connection.
L<SSL_shutdown(3)> can be used to shut down the
TLS/SSL connection.

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.
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.
