Создание уникального глобального идентификатора (GUID)

function GUID()
{
    if (function_exists('com_create_guid') === true) {

        return trim(com_create_guid(), '{}');
    }

       return sprintf('%04X%04X-%04X-%04X-%04X-%04X%04X%04X', mt_rand(0, 65535), mt_rand(0, 65535), mt_rand(0, 65535),
           mt_rand(16384, 20479), mt_rand(32768, 49151), mt_rand(0, 65535), mt_rand(0, 65535), mt_rand(0, 65535));


};

echo GUID();

Set up Nginx

Now we need to add a new snippet with ssl-params.

Go to snippets directory and create a new one.

cd /etc/nginx/snippets
nano ssl.conf

Add the following lines, save and exit the editor (Ctrl+X, Y, Enter).

ssl_session_timeout 1d;
ssl_session_cache shared:SSL:50m;
ssl_session_tickets on;

ssl_protocols TLSv1.2;
ssl_ciphers ECDHE-RSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-SHA:ECDHE-RSA-AES256-SHA384;
ssl_ecdh_curve secp384r1;
ssl_prefer_server_ciphers on;

ssl_stapling on;
ssl_stapling_verify on;

add_header Strict-Transport-Security "max-age=15768000; includeSubdomains; preload";
add_header X-Frame-Options DENY;
add_header X-Content-Type-Options nosniff;

Then you have to create a directory for certificates snippets.

mkdir certs
cd certs

Create a new file that will hold certificate’s params.

nano example.com

Add paths to the wildcard certificate.

ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem;
ssl_trusted_certificate /etc/letsencrypt/live/example.com/fullchain.pem;
