End-to-end encryption (E2EE) is an application of cryptography in communications systems between endpoints. E2EE systems are unique in providing features of confidentiality, integrity and authenticity for users. Improvements to E2EE strive to maximise the system's security while balancing usability and availability. Users of E2EE communications expect trustworthy providers of secure implementations to respect and protect their right to whisper.
