An SSL cipher, or an SSL cipher suite, is a set of algorithms or a set of instructions/steps that helps to establish a secure connection between two entities. SSL cipher suites determine the method through which a secure connection will take place between both entities. This communication could be taking place through HTTPS, FTPS, SMTP, …

SSL (Secure Sockets Layer) connection is a connection that provides secure communications on the Internet for such things as web browsing, e-mail, instant messaging, and other data transfers. Although SSL was replaced by an updated protocol called TLS (Transport Layer Security) some time ago, “SSL” is still a commonly used term for this technology. How …
An SSL/TLS certificate is a file installed on a website’s origin server. It’s simply a data file containing the public key and the identity of the website owner, along with other information. Without a server certificate, a website’s traffic can’t be encrypted with TLS. SSL/TLS certificates are the most popular type of X.509 certificate. SSL/TLS …
We have two methods to use update-ca-trust or trust anchor to add a CA certificate on Linux. We need to install the ca-certificates package first with the command yum install ca-certificates. Understanding Root CA certificate SSL certificates operate on a structure called the certificate chain — a network of certificates starting back at the issuing …
Server certificates are known as SSL/TLS certificates. It verifies and validates the identity of the certificate holder or applicant before authenticating it. It also establishes an encrypted communication channel and switches the protocol to HTTPS once installed on the server. What is SSL certificate Server certificates are the most popular type of X.509 certificate. SSL/TLS …
A Security Certificate (also known as a public-key certificate) is an electronic document used to prove ownership of a public encryption key. A Security Certificate is used in TLS to associate encryption keys with internet domains (such as www.howtouselinux.com). A security certificate is a small data file used as an Internet security technique through which …
Both SSL and TLS protocols aim to protect sensitive information used during transactions such as payment processing that requires authentication to prove the identity of our server to the users. TLS 1.3 is the latest version of the TLS protocol. It is a descendent of SSL and is regarded to be more powerful and effective. …
The port number for SSH is 22 by default. Whenever we run a command through default SSH port number 22, a connection is established between client and server. Every connection initializes through this port. This tutorial explains why and how to change the default SSH port in Linux. Why should we change the default SSH …
SSH (Secure Shell) is a widely used network protocol to securely log onto remote systems. One of its features is /SSH Port Forwarding/ (or SSH tunneling). This functionality forwards encrypted connections between a local and a remote computer. There are 3 types of port forwarding: local port forwarding Reverse port forwarding dynamic port forwarding The …
A self-signed certificate is a security certificate that is not signed by a certificate authority (CA). These certificates are easy to make and do not cost money. The Self-signed SSL certificate is mainly used for non-production applications or other experiments. In this article, we will cover 2 ways to create a self-signed certificate. Is a …
