Protect Your Privacy With An XMPP Tor Hidden Service (Prosody)

~ Tom's IT Cafe ~ Leave a comment

The world is changing fast.
Yesterday’s mistake becomes today’s data leak – and tomorrow’s compromise.

Privacy is not a default setting.
It’s constant configuration and calibration.

You know how to install an IRC server as a Tor hidden service.
You’ve seen the modern features and modularity of the XMPP protocol.

A Tor hidden service protects both the server and the user.
This setup is designed to reduce exposure of IP addresses and limit metadata leakage.
It does not protect against compromised endpoints or user mistakes.

Run IRC As A Tor Hidden Service (Inspircd + Anope)

~ Tom's IT Cafe ~ 1 Comment

IRC with InspIRCd and Anope works well as an internet-facing service.
Your domain name, the TLS certificates and SASL authentication make it secure.
Cloaking hides your address from other users.

But what about IRC Operators and Network Admins?
They can see the addresses/hosts the clients connect from.

As an IRC Operator you can increase the trust in your services.

You will learn now how to run InspIRCd as a Tor-only hidden service.

XMPP – The Middle Ground Of Instant Messaging (Prosody)

~ Tom's IT Cafe ~ 1 Comment

XMPP or Extensible Messaging and Presence Protocol is an open communication protocol.
It has been actively developed since it was introduced in 1999.
Over time, a large part of its user base migrated to centralized cloud platforms.

IRC is a simple, reliable, text-based protocol.
Matrix is a robust but more complex protocol with higher resource requirements.
XMPP sits between them, closer to IRC in simplicity while offering more modern features.

In this article you will learn to install a private, non-federated XMPP server.

Host your own Matrix on Tor, no public IP, zero tracking.
By running Matrix over Tor, you eliminate exposure to public servers and keep your chats private.

This isn’t just another guide – it’s a battle‑tested recipe for keeping your Matrix chats private on Tor.

Breadcrumbs In The Wire – Why OPSEC Is Important

~ Tom's IT Cafe ~ Leave a comment

OPSEC Is Not For The Military

Operational Security (OPSEC) isn’t a military secret – it’s a survival tool.
People think it’s for soldiers, spies, or hackers.
But it’s for civilians. For you.
Every day, you leave trails: where you go, who you talk to, what you buy.
Someone is watching. Someone is connecting the dots.
OPSEC is the discipline of controlling your own story before someone else writes it for you.

The Ciphered Mind – Encrypted Journaling with Org-mode

~ Tom's IT Cafe ~ Leave a comment

By DeadSwitch | The Cyber Ghost

“Your thoughts should never be anyone’s business. Encrypt the silence.”

In a world obsessed with sharing, I write to forget – not to be remembered by others. My journal isn’t a scrapbook for dopamine or a backup for someone else’s algorithm. It’s a log of operations, and operations require secrecy.

So I encrypt mine. With Emacs. In plain text.

This is how DeadSwitch keeps a daily log that even the digital gods can’t peek into.

Why Encrypt a Journal?

Because the mind is sacred.
Because ideas are weapons.
Because tomorrow’s threat often begins with yesterday’s leak.

Encrypted journaling isn’t about fear. It’s about respect – for your thoughts, your process, your silence.

The Setup – Emacs, Org-mode, and GPG

Here’s the toolbox:

  • Editor: Emacs
  • Format: Org-mode
  • Encryption: GnuPG
  • Extension: org-crypt
  • Storage: Offline, local, under your terms

Emacs Configuration

Drop this into your config:

(require 'org-crypt)
(setq org-tags-exclude-from-inheritance '("crypt"))
(setq org-crypt-key nil) ;; uses your default GPG key
(org-crypt-use-before-save-magic)

This tells Emacs to automatically encrypt any headline tagged with :crypt: before saving.
Decryption happens only when you open the file – and stays in RAM.

A Sample Entry

* May 2025 :crypt:

** [2025-05-04 Sun]
- 5k run - 22:18 [2025-05-04 Sun 09:06]
- Cold shower - difficulty: easy [2025-05-04 Sun 09:28]
- New idea: Emacs Lisp for internal ops [2025-05-04 Sun 14:24]

Your operations, encrypted. Your timestamps, precise. Your log, protected.

Timestamps and Logging Shortcuts

  • C-c . – insert date
  • C-u C-c . – insert date and time
  • C-c ! – inactive timestamp
  • C-u C-c ! – inactive date and time

You want traceability without noise. Emacs delivers.

Why Not Notion, Joplin, Obsidian, or Others?

Because I don’t trust clouds.
Because their encryption isn’t mine.
Because their sync means exposure.
Because when I type, I want code – not JavaScript trying to sell me my own thoughts.

Final Note

“Encryption is not paranoia. It is self-respect.”
