CWALock is a plugin that allows players to protect blocks with locks and keys.

Players can place locks on chests, barrels, shulker boxes, doors, and trapdoors. Each lock creates a unique key with an ID and coordinates. To open a protected block, you need the correct key. Administrators can use a master key that opens any lock.

Features:
- Protection for chests, barrels, shulker boxes, doors, and trapdoors
- Unique keys for each lock
- Master key for administrators
- Crafting recipes for locks, keys, and master key
- Redstone protection (buttons, levers, pressure plates)
- Lock data saved to file

Commands:
/masterkey - gives a master key (requires cwalock.admin permission)

Permissions:
cwalock.admin - access to master key and ability to break other players' locks

Works on Minecraft versions: 1.17 - 1.20.4 (compatible up to 1.21+)
