## What it is
OpenDHT is a lightweight C++17 distributed hash table (DHT) library providing an easy-to-use distributed in-memory data store with redundancy, data signing, and encryption via GnuTLS. It includes bindings for C, Rust, and Python 3, plus a REST API and CLI tools like dhtnode.

## Use cases
- build a peer-to-peer distributed key-value store
- run a DHT node on a public network
- store and retrieve signed or encrypted values across a distributed network
- add decentralized data storage to a C++ or Python application
- bootstrap a lightweight P2P network for IoT or messaging apps

## When to choose
- you need a lightweight, scalable distributed hash table with C++17 or Python bindings
- you want built-in public key cryptography for signed/encrypted distributed data
- you need IPv4 and IPv6 support with resilience to network disruption
- you're building peer-to-peer applications like messaging or decentralized storage

## When to avoid
- you need persistent on-disk storage rather than an in-memory distributed store
- you want a managed or centralized database with strong consistency guarantees
- you need a full-featured DHT with extensive tooling outside the C++ ecosystem
