CyberChef
The Cyber Swiss Army Knife - a web app for encryption, encoding, compression and data analysis
Project mention: Show HN: Txtl – Fast static website of text utilities | news.ycombinator.com | 2025-02-25I have Cyberchef locally, just unzip it and run. It has an auto function that I only manage to get working by mistake. So as is said above just learn that instead.

Project mention: Nomad, communicate off-grid mesh, forward secrecy and extreme privacy | news.ycombinator.com | 2024-08-15
Reticulum is incredibly versatile and has an entire ecosystem of tools under development. NomadNet is just one of the messengers. There is Sideband, a mobile app client (https://github.com/markqvist/Sideband), and Reticulum MeshChat, developed by Liam Cottle which is a browser based client https://github.com/liamcottle/reticulum-meshchat.
Reticulum can work over anything that has a throughput greater than 5 bits a second (yes, bits) and a MDU of 500 bytes. Not only can it work over hundreds of different carriers but each of these carriers can be apart of the same network.
I threw together a quick proof of concept of it working over HF radio. I setup two nodes about 144 km (90 miles) separate. Both were ICOM-7300's with a Raspberry Pi 5 driving the software modem that would take packets from Reticulum and send them over the air. https://www.youtube.com/watch?v=blwNVumLujc
Node 1 was out in the field while Node 2 was back at my house. Node 2 had two interfaces setup, one for the HF modem and another connected to the TCP testnet. This means that Node 1 could access any peer that was over on the TCP testnet.
Here is a quick primer on Reticulum that explains some of the basic concepts: https://www.youtube.com/watch?v=q8ltLt5SK6A
