Following Part 2 of the series, the second component to be set up is the Smallstep Certificate Authority server. Smallstep is a lightweight CA I use to issue and manage TLS certificates for my internal services. It makes it easy to automate cert handling without relying on external CAs such as Let’s Encrypt, nor do I have to reveal details about my domain names to the public.

Docker Compose

The Docker Compose file and configuration of Smallstep is located in /containers/smallstep base folder.

I’ve been using SSH certificates for years to connect to my servers no matter where they are, and they’ve always worked perfectly. I’ve used both client and server certificates, but since I automated the setup I sometimes forget the steps. This guide records the process for future reference.

What are SSH Certificates?

Just as HTTPS certificates verify our websites, SSH certificates confirm the identity of both server and user before any connection begins. When you first connect to a new SSH server, you’ve no doubt seen that warning about an unknown host key and clicked “yes” because you just created the machine and assume it’s safe. SSH certificates remove that guesswork. A trusted authority signs the server’s public key in advance, and your client automatically checks that signature on every connection. On the flip side, the server only accepts user keys that carry a valid signature from the same authority. Certificates can include expiration dates and be revoked if necessary, giving you precise control over who can connect and for how long. With SSH certificates in place, there’s no need to blindly trust that initial prompt.

About This Build
This build explores the design of Tharn Wildvein, a Half-Orc Barbarian in Dungeons & Dragons 5e inspired by the essence of Wolverine — the feral loner, the unstoppable survivor, the relentless fury in the face of overwhelming odds.

Rather than a direct adaptation, this is a fantasy reinterpretation: a savage warrior whose power is not bestowed by science or sorcery, but awakened by rage, trauma, and unrelenting instinct. His body is the weapon — muscle, claw, and willpower forged through countless battles.

About This Build
This build explores the design of Jaxen Vantrell, an Armorer Artificer in Dungeons & Dragons 5e inspired by the concept of Iron Man — especially the Heroes Reborn saga, where the character’s brilliance, adaptability, and sheer variety of power suits took center stage.

Rather than a direct conversion, this is a high fantasy reimagining of the archetype: a genius arcane engineer who doesn’t rely on destiny or lineage, but on crafted armor, magical augmentation, and relentless iteration. Every infused item, every armor model, every spell reflects a different version of “the suit” — modular, reactive, and purpose-built.

Design Note
Zareth Kael is a personal homage to one of my all-time favorite characters — The Darkness, from the Top Cow comic series. I read the entire run starting from the 1990s, and the idea of a reluctant antihero bound to an ancient, sentient force of shadow left a permanent impression on me.

In reimagining this concept within 5E, I wanted to portray the Darkness not just as a weapon or curse, but as a primordial entity — protective and parasitic, elegant and monstrous. Its presence isn’t loud or overt, but it shapes every moment Zareth lives through, watching from behind a cracked mirror and whispering between spells.

About This Build
This step-by-step breakdown traces the mechanical and narrative design behind Zareth Kael, my reinterpretation of The Darkness comic character in Dungeons & Dragons 5e. As someone who grew up reading The Darkness from the 1990s onward, this project is more than just a character — it’s a tribute to one of my favorite antiheroes.

I wanted to explore how Jackie Estacado’s cursed, sentient power could be expressed through official 5e mechanics, while leaning into my current interest in flawed, complex protagonists. This build is designed for a homebrew game I may run someday — dark, thematic, and soaked in psychic tension.

Earthdawn Reforged – A Heroic Take on a Legendary World

What happens when you take the lore-rich world of Earthdawn and explore it through the lens of Age of Sigmar: Soulbound’s heroic engine?

Welcome to Earthdawn Reforged — a personal design experiment where I’m reimagining the Earthdawn setting using the mechanics of Soulbound. This isn’t a full system rewrite or community project — just something I’m exploring for my own creative enjoyment, to see how the themes of survival, horror, and magical legacy can play out in a more fast-paced, cinematic system.

Once your server is up and running, you can configure a peer. The process is nearly identical to setting up the server—allowing you to easily replicate these steps for adding multiple peers. As always, ensure that all commands are executed as the root user.

Generate keys

Each peer requires a unique public/private key pair to establish identity and secure connections, just like the server . Run the following commands to create the required files:

Refer to this article for a brief overview, prerequisites, and server details. Ensure you run all commands as the root user.

Generate keys

Each server requires a unique public/private key pair to establish identity and secure connections. Run the following commands to create the required files:

(umask 0077; wg genkey | sudo tee /etc/wireguard/privatekey | wg pubkey | sudo tee /etc/wireguard/publickey)
wg genpsk   # Generates a preshared key for Peer A (adds an extra layer of encryption)

Create configuration file

Create a configuration for the new interface. In Wireguard, the configuration file’s name determines the interface name. For example, if you create /etc/wireguard/wg0.conf, the interface will be named wg0.
