SSL (Secure Sockets Layer) is a security protocol that functions to secure communication between clients and servers over the internet. SSL is used to protect sensitive data such as login information, credit card data, 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 data on the sender’s side and then decrypting it on the recipient’s side. 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 Create a Self-Signed SSL Certificate for Nginx in Ubuntu 24.04
This blog post is about creating a self-signed SSL certificate for the Nginx web server in Ubuntu 24.04 OS. A Self-Signed SSL certificate is just like the other SSL certificates with a certificate private key and cert file. The only difference is that certificate authorities do not trust the self-signed SSL certificate included with the web browsers. Self-signed certificate in most cases is used when there is no domain associated with your server, otherwise, if there is a domain it is better to use CA-Signed (Certificate Authority) SSL certificate. However in both cases with or without a domain(only IP address) we can install a self-signed SSL certificate. The CA-Signed can only be installed on a domain.
Guide to Testing an SSL Connection Using OpenSSL
In this tutorial, we will provide helpful information about SSL certificates, SSL connections and testing an SSL connection using OpenSSL. The SSL certificates are necessary for domain names since they display essential information for verifying the website’s owner. It also encrypts the web traffic with SSL/TLS, including the public key, the certificate authority, and the associated subdomains. The traffic is through HTTPS (Hypertext Transfer Protocol Secure) when there is a valid SSL certificate, and this technology encrypts the data sent between a website and a browser. It prevents hackers from seeing or stealing any information, like personal data.
In the following paragraphs, we will proceed with the OpenSSL as software, how to install it, and how to test the SSL connections. Let’s get started!
