I need a simple key crate plugin.

I need a simple crate plugin.
I really need this soon, Thanks guys.

IT MUST HAVE
- be fully customisable where i can change what you can get out of the crate
- be used with a key that is enchanted and cannot be crafted by players
- have a chance system
- no gui, just click and get the items
- /crate for the start of all commands
- /crate givekey <cartename> <player> <amount>
- /crate set <cratename> or /crate give <cratename> <player>
- permissions
- crate.use - use the crate
- crate.admin - use all the commands

IT SHOULD HAVE

- particles around then chest *configurable*
- Knock back if a player has no key
- Fireworks on open

IT COULD HAVE

- In came configuration *not necessary*
