libyojimbo is a new, easy-to-use library for creating secure client/server network protocols over UDP.
It is designed around the networking requirements of competitive realtime multiplayer games such as first person shooters and action games. As such it provides the absolute fastest, most time critical networking layer over UDP, with a client/server architecture supporting up to 64 players per-dedicated server instance.
libyojimbo is currently in pre-release for early feedback. Right now it provides support for: cryptographically secure authentication, client/server connection management, encryption for packets sent over UDP, as well as a bitpacker and framework for extending the protocol with custom packet types. Preliminary support for reliable-ordered messages and data blocks is included in the latest preview release.
Current work is focused on implement security features that silo client connections into their own heaps, so a malicious attacker is not able to mount protocol level attacks to exhaust server resources. Next, packet fragmentation and reassembly will be implemented and libyojimbo 0.3 is ready for release.
For more details please refer to the roadmap.
