Switching from HTTP to HTTPS: A Guide for Website Security

This guide provides a comprehensive overview of how to switch your website from HTTP to HTTPS for enhanced website security. more secure and protected.

To create a Certificate Signing Request (CSR) for an SSL/TLS certificate, you'll need to perform the following steps:

1. Generate a private key for the CSR. You can use OpenSSL to generate a 2048-bit RSA key using the following command:

 OpenSSL req -new -newkey rsa:2048 -nodes -keyout mymenuinc.key -out mymenuinc.csr

for CSR you need to add some Basic detail like


Common Name :
 An SSL certificate issued for domainname.com is not valid for www.domainname.com.

 you are requesting a wildcard certificate, add an asterisk (*) on the left side of the Common Name (e.g., *.domainname.com or *.www.domainname.com).

Organization: Organization name

State: State name

City: City name

Organizational Unit: "Engineering" or "Human Resources"

When you generate CSR certificate then automatically generate a key file

2. Save the private key and the CSR file in a safe location. You'll need to provide the CSR file to a Certificate Authority (CA) to obtain an SSL/TLS certificate.

3. Submit the CSR to a trusted CA and follow their instructions to obtain the SSL/TLS certificate. The CA may require you to verify your domain ownership before issuing the certificate.

4. Install the SSL/TLS certificate on your server, along with the private key and any intermediate certificates provided by the CA. The steps to do this depend on your web server software and hosting environment.

To configure HTTPS on an Apache2 web server, you'll need to perform the following steps:

1. Install an SSL/TLS certificate on your server. You can obtain a certificate from a trusted Certificate Authority (CA) or generate a self-signed certificate for testing purposes.

2. Enable the SSL module in Apache2 using the following command:

 sudo a2enmod ssl

3. Configure the SSL virtual host in Apache2. Edit the Apache2 configuration file for your website using your preferred text editor. The default location of this file is usually "/etc/apache2/sites-available/default-ssl.conf". Make sure that the following directives are set in the virtual host configuration:

 SSLEngine on
SSLCertificateFile /path/to/your_certificate_file
SSLCertificateKeyFile /path/to/your_private_key_file

4. Redirect HTTP requests to HTTPS by adding the following lines to your virtual host configuration file:

 RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

5. Save and close the configuration file, then restart Apache2 to apply the changes:

 sudo systemctl restart apache2

Your website should now be accessible over HTTPS. Make sure to test the SSL configuration using an SSL checker tool to verify that it is working correctly.
