A non-owner can’t open it, break it, push it with a piston, power it open with redstone, or blow it up. It survives TNT and Creepers. A zombie can’t break it down, and a villager can’t wander through it.

Seal of the Padlock
This door is mine, and nothing gets through it but me.
Why it exists
A door, trapdoor or fence gate should actually stay closed to everyone but you — not just look locked, but stay off-limits to other players, mobs, pistons, explosions and redstone.
What it does
Craft a Seal of the Padlock and right-click it against a door, trapdoor or fence gate to seal it. The binding is server-side and permanent until you remove it yourself with Shift + right-click.
You keep full control at all times, and don’t need the Seal in hand except to remove the binding. The block holding the door up is protected too — otherwise removing it would pop the door off and bypass the seal.
Works with any vanilla-style door, trapdoor or fence gate, including modded ones that extend the vanilla block classes. It is not a claim system: it protects the access, not the whole house.
How it fits
The Pergamena del Lucchetto is found in dungeon chests. Server operators can be granted a dedicated permission to bypass any seal for legitimate recovery; it is off for regular players by default.
