Introduction
SSL (Secure Sockets Layer) is a security protocol that provides communication security over the internet. It is a cryptographic protocol used to establish an encrypted connection between a web server and a web browser. This connection ensures that all data passed between the server and the browser remains private and secure. With SSL, users can rest assured that their private data is safe and secure.
SSL works by creating an encrypted connection between a web server and a web browser. This connection is established using a cryptographic protocol, which uses a combination of public and private keys to authenticate and encrypt data. The public key is shared with the server, while the private key is kept by the user. All data transmitted between the server and the browser is encrypted using the public key, which ensures that the private data remains secure and confidential.
Having an SSL certificate on your website is essential for security and privacy. But if you don’t want to spend money on a certificate, you can get it for free. In this blog post, we’ll show you how to setup free SSL in Ubuntu.
Step 1: Install Certbot
The first step is to install Certbot, which is a free, open source tool for managing SSL certificates. To install Certbot, open up a terminal and run the following command:
sudo apt-get install certbotStep 2: Generate a Certificate
Once Certbot is installed, you can generate a certificate with the following command:
sudo certbot certonly --manual --preferred-challenges http --agree-tos -d example.comReplace “example.com” with the domain name for your website.
Step 3: Setup Auto Renewal
To make sure your certificate doesn’t expire, you can setup automatic renewal with the following command:
sudo certbot renew --dry-runThis will run a “dry run” of the renewal process and check if your certificate is close to expiring.
Conclusion
In this blog post, we showed you how to setup free SSL in Ubuntu. We started by installing Certbot, then generating a certificate, and finally setting up auto renewal. With these steps, you can ensure that your website is secure and private.
