End-to-end Encryption

End-to-end encryption (E2EE) is an uninterrupted protection of the confidentiality and integrity of transmitted data by encoding it at its starting point and decoding it at its destination. It involves encrypting clear (red) data at source with knowledge of the intended recipient, allowing the encrypted (black) data to travel safely through vulnerable channels (e.g. public networks) to its recipient where it can be decrypted (assuming the destination shares the necessary key-variables and algorithms).
