# Eleuth Security Core in Java

This repository contains java classes, helpers and utils for Eleuth to be used in different implementations.

### Diffie Hellman

Diffie-Hellman is a way of generating a shared secret between two people in such a way that the secret can't be seen by observing the communication. That's an important distinction: You're not sharing information during the key exchange, you're creating a key together.

Eleuth uses Diffie-Hellman to perform an end-to-end key exchange. This (temporary) secret key is used to encrypt p2p communications with an AES-256 cipher.

### Encrypted Sessions

Encrypted Session class attaches to a session and uses diffie hellman key agreement to encrypt data.

### AES File Encryption

In other to back-up the Eleuth data and reuse it in other devices, user first needs to encrypt the data. AES File Encryption helps user in this process.

### Generators

Generator is an interface to generate different kind of data, mostly for initializing Eleuth in the device.

For example, `KeyStoreGenerator` generates initial keystore which holds user public and private keys.
