About

AntiSeedCracker protects Paper, Folia, and Purpur *.21.4+ servers from world-seed cracking. It scrambles structure seeds, spoofs Join Game and Respawn seed packets per player, offsets generated ores with a server-local HMAC key, obfuscates selected structure patterns, redirects Ender Eyes, blocks seed and locate commands, filters tab completion, tracks violations with configurable punishments, alerts administrators, and exposes a trusted seed-access service for approved plugins.
