  • SHA-1 Deprecation: Pro, Con, or Extend?

    I read Ryan's article about why SHA-1 should be deprecated faster and why we should veto the proposed extensions. It is an excellent explanation of what's going on. I highly recommend it (and look forward to the complete series when he publishes it):

  • Legacy Verified: Legacy Solutions

    While the previous post explored the historical context in which the SHA-1 deprecation fits, and in the many failures to respond adequately to known risks, it didn’t really address the actual Legacy Verified proposal made by CloudFlare and Facebook, and subsequently endorsed by Twitter, nor how it attempts to mitigate the concerns with continuing SHA-1 allocation.

  • Let’s Encrypt Now Being Abused By Malvertisers

    Encrypting all HTTP traffic has long been considered a key security goal, but there have been two key obstacles to this. First, certificates are not free and many owners are unwilling to pay; secondly the certificates themselves are not always something that could be set up by a site owner.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
