lime src b7b5356a463eb80021bbb9425b2d0eb08dfd9195f260a4d0ddb797b9ea4ef661 An encryption library for one-to-one and group instant messaging LIME is an encryption library for one-to-one and group instant messaging, allowing users to exchange messages privately and asynchronously. It supports multiple devices per user and multiple users per device. LIME offers two major security benefits to instant messaging users: - end-to-end encryption, which means that only you and your contact (and not even the server) can decrypt the content that you shared - perfect forward secrecy, which ensures that encrypted messages cannot by decrypted by a third party, even if a key is compromised in the future LIME is composed of a portable client library coupled with a public key server developed by Belledonne Communications to allow end-to-end encryption for messaging, without having to exchange cryptographic keys simultaneously. Main features are: - end-to-end encryption based on modern Elliptic Curve Diffie-Hellman(ECDH) - perfect forward secrecy with double ratchet algorithm - designed for group communications - asynchronous messaging system based on pre-positioned keys - man-in-the-middle (MITM) detection based on ZRTP auxiliary secret - signaling protocol agnostic bero <bero@lindev.ch> https://linphone.org
