## What it is
A hands-on workshop for learning cryptographic engineering through a set of exercises using libsodium in Node.js. It teaches practical crypto concepts via guided problems rather than being a production library.

## Use cases
- learn cryptography through hands-on exercises
- practice using libsodium in nodejs
- teach a crypto engineering workshop
- understand encryption, signing, and hashing basics
- self-study cryptographic engineering

## When to choose
- you want to learn applied cryptography with libsodium
- you prefer exercise-driven learning in JavaScript
- you are running a workshop or study group on crypto basics

## When to avoid
- you need a production cryptography library to ship in an app
- you want formal or academic cryptography theory
- you need a maintained tool rather than educational material

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: cryptography, developer-tools
- domain: security, developer-tools, tutorials
- platform: cross-platform
- tags: cryptography, workshop, libsodium, exercises, education, nodejs
