     * Considering that

     *
     * The following decisions have been made.
     *
     * 1. This library uses TLS 1.2 by default for pre PHP 7.2.0.
     * 2. Starting from PHP 7.2.0 this library uses the TLS negotiation by PHP, which
     *    means TLS 1.2 if available, otherwise falls back to a lower TLS version.
