How to Install Let’s Encrypt on AlmaLinux 10

January 21, 2026 by Jeff Wilson

SSL (Secure Sockets Layer) is a security protocol that functions to secure communication between clients and servers over the Internet. SSL protects sensitive data such as login information, credit card numbers, and other personal information sent over the internet. Secure Sockets Layer, or SSL, works by using encryption techniques, namely changing the data sent into a form that cannot be read by unauthorized parties. This is done by encrypting the data on the sender’s side and decrypting it on the recipient’s. Nowadays, websites are expected to use SSL certificates. In this article, we will show you how to install Let’s Encrypt on AlmaLinux 10.

How to Install HTTPS Protocol on Ubuntu 24.04

January 19, 2026 by Jeff Wilson

HTTPS is the secure form of the Hypertext Transfer Protocol (HTTP). It employs the SSL/TLS protocol for encryption and authentication, ensuring secure communication between the web server and the browser. This protocol encrypts HTTP requests and responses to prevent unauthorized access to the information exchanged between your browser and the web server. Without HTTPS, someone can intercept and steal sensitive information from your website visitors, including login credentials and credit card details. After installing Apache or Nginx on Ubuntu 24.04, the service will only run on port 80 by default. To enable HTTPS protocol on Ubuntu 24.04, we need to configure Apache or Nginx to listen on port 443 and install an SSL certificate. In this article, we will show you how to enable the HTTPS protocol on Ubuntu 24.04.

Static IP addresses are used for devices that require consistent, dependable access, such as servers, printers, and other network devices, as they ensure that other devices can consistently locate and connect to them. In this article, we will show you how to configure a static IP address on AlmaLinux 10.
