Cipher Block

The Cipher Block lets you encrypt and decrypt messages using an innovative ripped off from OpenEnder method - item stacks! Your unique items will create the key used for encryption.

Recipe

NOTE: The stone bricks can be any type of stone bricks.

Usage (Computer API)

Setting the key

The key is derived from the six item stacks in the Cipher Block's inventory. Remember that the item stacks need to be identical every time you want to encrypt/decrypt a message with the same key.
