End-to-End Encryption
A security protocol that ensures data remains encrypted throughout its entire journey from sender to recipient, with only communicating parties having access to the decryption keys.
End-to-End Encryption (E2EE)
End-to-end encryption represents a cornerstone of modern secure communications, providing the highest level of data privacy by ensuring that only the intended participants can access the transmitted information.
Core Principles
