Comprehensive security system to protect against packet-sniffing attacks, XUID harvesting, privilege escalation, bot flooding, and XUID impersonation. - Stream cipher: per-session XOR cipher with 4-message handshake via CustomPayloadPacket (MC|CKey, MC|CAck, MC|COn). Negotiated per-connection, backwards compatible (old clients/servers fall back to plaintext). - Security gate: buffers all game data until cipher handshake completes, preventing unsecured clients from receiving any XUIDs or game state. - Cipher handshake enforcer: kicks clients that don't complete the handshake within 5 seconds (configurable via require-secure-client). - Identity tokens: persistent per-XUID tokens in identity-tokens.json, issued over the encrypted channel, verified on reconnect. Prevents XUID replay attacks. Client stores server-specific tokens. - PROXY protocol v1: parses real client IPs from playit.gg tunnel headers so rate limiting, IP bans, and XUID spoof detection work per-player. - Rate limiting: per-IP sliding window (default 5 connections/30s) with pending connection cap (default 10). - Privilege hardening: OP requires ops.json, live checks on every command and privilege packet. Host-only server settings changes. - XUID stripping: PreLoginPacket response sends INVALID_XUID placeholders. - Packet validation: readUtf global string cap, reduced max packet size, stream desync protection on oversized strings. - OpManager: persistent ops.json with XUID-based OP list. - Whitelist improvements: whitelist add accepts player names with ambiguity detection, XUID cache from login attempts. - revoketoken command: revoke identity tokens for players who lost theirs. - server.log: persistent log file written alongside console output with flush-per-write to survive crashes. - CLI security logging: consolidated per-join security summary with cipher status, token status, XUID, and real IP. Security warnings for kicks, spoofing, and unauthorized commands.
