Instructions on how to install SSL certificate for website

Step 1: Set up a private IP address for the server when installing the SSL certificate for the website

To provide the best security, installing an SSL certificate for your website requires your website to have its own IP address. However, now there are many small web hosting packages with shared IP addresses, in which many different websites use the same location (IP) leading to low security and less guarantee.

Therefore, with a private IP address, you can ensure that traffic from your IP address only goes to your website and not another website.

If you don't already have a private IP address plan, you can ask your existing server/hosting provider to upgrade your account for a dedicated IP address. To upgrade this IP package, you need to pay the cost by year or by month.

In this step, you need to check if your web host has automatically activated the certificate. Activation of certificates takes 1 to 2 days to receive results.

However, if you want to manually activate the certificate, make the process faster. You can also do it yourself in the IP admin interface, your web hosting.

Go to the SSL/TLS administration and select Generate an SSL certificate and Signing Request. Fill full the information.

In the “Host to make cert for” box enter your domain name, and the Contact email box can be left blank. After filling in the information, you will see a window like the one below displayed on the screen.

Copy the first block of text. You need to use this CSR to provide your issuer with an SSL certificate so they can establish your identity.

Paste your CSR in the necessary frames. It will ask you for an approval email. This is the email address that proves you own the domain name. If not, you must create an email to get the email containing the final certificate. Follow the steps, and once completed the email address you will receive the .crt file.

Step 5: Configure the site

After you've installed an SSL certificate for your website and set up an SSL certificate, you need to reconfigure your site for the upcoming activities.

You can update all links to target sites using HTTPS links. This to link all pages pointing to sensitive URLs.

However, if you want to ensure that users can only use specific secure pages no matter what link they have, it is best to use a server-side approach to redirect non-HTTPS users. .

To do this, insert a code snippet at the top of the secure page. Here is one of the code snippets in PHP:

    // Require https
    if ($_SERVER[‘HTTPS’] != “on”) {
    $url = “https://”. $_SERVER[‘SERVER_NAME’] . $_SERVER[‘REQUEST_URI’];
    header(“Location: $url”);
    EXIT;
    }

Another server-side approach is to use mod-rewrite. This does not require you to change any site files, but will have to edit the apache configuration. Here is a mod-rewrite:

    RewriteEngine On
    RewriteCond %{HTTPS} off
    RewriteRule ^(cart/|checkout/) https://%{HTTP_HOST}%{REQUEST_URI}

This will ensure that if someone accesses the site via HTTP, they are automatically redirected to HTTPS.
