Log Decryptor

Drop a Client.log file below. The decryptor auto-detects both Kuro encryption schemes, applies the LUT XOR transform, and outputs human-readable text — entirely in your browser. No uploads, no servers.

Scheme A · Magic bytes 4B 47 4C 4F 47

Scheme B · Offset LUT with 256-byte key rotation

🔒 All processing is client-side only

Tool Notes

This tool implements both encryption schemes reverse-engineered from Kuro Games' Client.log format.

Scheme A uses a fixed magic header (KGLOG) followed by XOR with a static LUT.

Scheme B uses a rolling 256-byte key with position-based offset rotation. Auto-detection reads the first 16 bytes to determine which scheme applies.

Also available as a CLI tool: wuwa_ld on GitHub.
