KryptonPlus ⚡

KryptonPlus is a modernized, drop-in network stack optimization mod for modern Fabric Minecraft, based on PaperMC’s Velocity networking innovations.

It completely rewrites Minecraft’s packet encryption and compression pipelines with zero-leak native memory management, delivering maximum network throughput, lower server/client CPU usage, and ultra-low ping spikes.

✨ Key Features & Improvements

🚀 Velocity Native Pipeline: High-performance libdeflate compression and native AES encryption for lightning-fast packet handling.
🔄 Full ViaFabricPlus Compatibility: Intelligently handles multi-version byte streams, packet length shifts, and dynamic Netty pipeline injections without crashes or disconnects.
🛡️ Zero-Conflict Coexistence:
- Designed to work alongside e4mc without conflicting login/cipher redirections.
- Dynamically respects PacketFixer packet limits without crashing on large payloads.
- Compatible with ResourceTrimmer, TT20, and Eunomia.
🧹 Instant Memory Cleanup: Unused native buffers and compression decoders are cleanly dereferenced as soon as network channels close.
☕ Java 27 Ready: Built and tested with modern Java runtimes (Java 21, 25, 27).
