That's an important distinction: You're not sharing information during the key exchange, you're creating a key together.\n\nEleuth 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. \n\n- *Tell me more! What it really is?* [read](https://security.stackexchange.com/questions/45963/diffie-hellman-key-exchange-in-plain-english)\n- *How?* [look](https://github.com/ep2p/eleuth-java-security-core/tree/master/src/main/java/com/github/ep2p/encore/diffieHellman)\n- *Show me a simple test?* [look](https://github.com/ep2p/eleuth-java-security-core/blob/master/src/test/java/com/github/ep2p/encore/diffieHellman/EncryptedSessionTest.java)\n\n### Encrypted Sessions\n\nEncrypted Session class attaches to a session and uses diffie hellman key agreement to encrypt data.\n\n### AES File Encryption\n\nIn 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.\n\n### Generators\n\nGenerator is an interface to generate different kind of data, mostly for initializing Eleuth in the device.\n\nFor example, `KeyStoreGenerator` generates initial keystore which holds user public and private keys.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fep2p%2Fencryption-core","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fep2p%2Fencryption-core","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fep2p%2Fencryption-core/lists"}
