# yojimbo

**yojimbo** is a network library for client/server games written in C++.

It's designed around the networking requirements of competitive multiplayer games like first person shooters. 

Generally speaking, if you have a custom game engine written in C++ and you want to network your game, yojimbo is a really good choice.

It has the following features:

* Cryptographically secure authentication via [connect tokens](https://github.com/networkprotocol/netcode/blob/master/STANDARD.md)
* Client/server connection management and timeouts
* Encrypted and signed packets sent over UDP
* Packet fragmentation and reassembly
* Bitpacker and serialization system
* Unreliable-unordered messages for time sensitive data
* Reliable-ordered messages with aggressive resend until ack
* Data blocks larger than maximum packet size can be attached to reliable-ordered messages
* Estimates of latency, jitter, packet loss, bandwidth sent, received and acked per-connection

yojimbo is stable and production ready.
