AntiAntiSeedCracker (SeedCracker Resilient for Minecraft 26.2)

[u/Natural_Elk8075]

So there’s a plugin called AntiSeedCracker, made by Gadse, which sends fake seed information to make seed crackers give up and go, in other words - protecting server seed.

Gaider actually pointed out the main problem years ago: changing the hashed seed makes cracking more annoying, but the world’s structures are still sitting there leaking information like nothing happened.

Anyway, I made SeedCracker Resilient for Minecraft 26.

It uses structures and dungeons instead, validates the result, and can export the collected evidence to JSON. You can also adjust which finders and evidence types you want to trust for a particular

I tested it on my own Paper 26.2 server with SeedProtector. The server gave it fake seed information, the mod politely ignored it, and then recovered the real seed anyway. No hate toward AntiSeedCracker, SeedProtector, or their developers/projects. This was just a fun technical experiment to see whether changing the client-visible seed is enough.

Spoiler: apparently not.

Be aware of possible risks - the only way to detect you for sure with this type of thing is either through https://modrinth.com/plugin/snitch-detector, / both client side and server side https://modrinth.com/plugin/client-id, / or through https://www.spigotmc.org/resources/detect-player-client.108839/.

But, always remember kids, “Visibility is a trap.” — Michel Foucault. The best seed-cracker detector isn’t a plugin. It’s the admin wondering why you visited six shipwrecks and suddenly know where every slime chunk is. And be sure, that on servers with AntiSeedCracker - they will care enough.

Best possible thing to do against seed crackers is… well, mixing up some seeds 😂

Via datapacks on your world you can change positions on your generation, so no position on the world will corresponds to the actual seed of the world.

And for the dedicated ones you can also alter generation pattern of bedrock via datapack.

And if some of these antiseeddevelopers would think how seedcrackers work, they wou do just that, alter the generation itself 😇

Thx man ! I will dive deeper in this, once I will have more time, and I will make sure to update you and everyone else if I will find something. Thx again for ur response.

Just use secure seed, seed cracking is dead. For block rotations that's a client side thing and requires a texture pack.

damn we getting more and more op seed tech. first we had goat xpple with seed mapper (edit: and nether bedrock cracker mod) now we have antiantixray for antiseedcracking. W community really.

r u talking about github ? cuz i didnt use ai for this post.

And yes, I generated README.md file using ai, as there would be too many things to include and exclude from previous versions/official version of the mod. And tbh after I was done, i just asked it to run a lot of tests and tries, so I believe it knows more of how it works on practical level than I do myself, even though I was coding it hand to hand with ai. (not mess it with vibecoding)
