Let’s Encrypt is a Certificate Authority which is able to create and release free SSL/TLS certificates we can use to enable encryption and secure our websites. All the biggest hosting providers allow their customers to request Let’s Encrypt certificates in a user-friendly way, via administration panels like Cpanel or Plesk. If we have SSH access to a remote host, however, we can obtain a Let’s Encrypt certificate from the command line, by using Certbot. In this article, we learn how to install Certbot on the most used Linux distributions, and how to use it to obtain and manage valid Let’s Encrypt certificates.

How to install Void Linux with LVM on LUKS encryption
Since all the major Linux distributions adopted Systemd as their init system, they progressively became more and more similar to each other. Void Linux is an exception: it was written from scratch entirely by volunteers, uses Runit as its init system and service manager, and, as its name may suggest, it was designed with simplicity in mind.
How to deploy a self-hosted Vaultwarden instance
Everyone, nowadays, has several accounts and credentials to take care of, that’s why everyone needs a decent and possibly open source password manager. When it comes to managing passwords there are many choices available on Linux: in the past, for example we talked about “pass”, a great, command line oriented, password-manager based on standard tools such as GPG and git. In this article we explore an alternative which can be the ideal solution for individuals and small organizations: Vaultwarden.
How to create encrypted git repositories with git-remote-gcrypt
Git is, by far, the most used version control system. Being it “distributed”, means that each user can clone its own full copy of a repository on which he can work even if offline, pushing changes to a remote only when ready. Git repositories are not designed to host sensitive information, but in certain situations, the ability of transparently encrypt the content of a repository can come in handy. The git remote-gcrypt helper is designed with this goal in mind.
Ansible Vault Tutorial
In previous tutorials we discussed Ansible, a great tool we can use for automation and provisioning. We talked about basic Ansible concepts, we saw some of the most used Ansible modules, how to manage variables and how to perform basic loops in playbooks; now it’s time to see how to protect sensitive information which sometimes may be needed to accomplish some tasks. In order to protect sensitive information when using Ansible, we encrypt them with Ansible Vault.
