+At first the library must be initialized; see
+L<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)>).
+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)>, 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)> or L<SSL_connect(3)>
+respectively.
+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.
