Privacy Tips

Lumen – A privacy-focused pastebin script

Hello folks,

I built Lumen because I wanted a pastebin that actually respects privacy. Most pastebins out there load tons of JavaScript, track you across the web, and keep your data indefinitely. Lumen takes a different approach: it supports password-protected pastes with end-to-end encryption, self-destructing pastes that burn after reading, Markdown rendering, and syntax highlighting. Everything expires automatically, nothing is permanent, and you get admin links to delete your own pastes without needing an account.

Features:

- Password-protected pastes with AES-256-GCM encryption

- Self-destructing pastes (burn after reading)

- Markdown rendering and syntax highlighting

- Automatic expiration (10 minutes to 30 days)

- Admin links for self-deletion

Privacy:

- No JavaScript, no tracking, no analytics

- End-to-end encryption for protected pastes

- IP addresses hashed with HMAC-SHA256

- No accounts required

Open source (AGPL-3.0), written in Go. Self-hosting is straightforward. Just build and run, or configure it with environment variables for production use.

Code audits and feedback are welcome.

Great, there is never too much open source software around. Is it deployed somewhere to look at?

It’s not deployed yet, but you can find the open-source code with photos on both

Actually refreshing to see a Go-based pastebin that isn't bloated with JS. The AES-256-GCM encryption for password-protected pastes is a must for anyone moving sensitive infrastructure audits. I'll be keeping this on my radar for Shadowservice ops. Great work on the HMAC-SHA256 IP hashing standardization of privacy is key right now. Awarded.
