## Offline Customization And Identification Protocol (OCAIP)

Allows connections to a server even when auth servers are unreachable.

The goal is to just to add a bit of auth to offline-mode, while allowing normal online connections.

### Features: 

- Offline logins can be restricted by a registration password  

- Offline logins can be restricted by a registration proof of work

### How it works (in a nutshell):  

1. Client creates a private key (this is kindof like a password but more secure)

2. Client connects to server

3. If the client hasn't connected before the server will prompt a registration password/proof of work

4. The server will remember the public key and later logins will be seamless

____________________________________________________

### Q&A:

- Where's the private key stored?

  The private key is stored in `.minecraft/ocaip.key`  

keeping a backup of the key is recommemded as losing it means  

you won't be able to access that account and will have to contact an admin or create a new one.

- How to reset user's account if they lost their public key (server sided)?

  Server hosts public keys are located in `ocaip/server_keys`. If a user lost their original

public key you can reset the account by removing their name and the key underneath the name

- My skin is the default one, can I change that?

  To have a skin, place your 64x64 pixel skin file into `.minecraft/ocaip_skin.png`.

**OCAIP**: because the acronym kindof sounds like "Oh, Cape" (due to the migrator cape).
