端到端加密（End to End encryption，E2EE）是一種通訊技術，透過傳輸層安全性協定（Transport Layer Security，TLS）實施的加密技術來保護訊息，使其只能由通訊用戶讀取，防止潛在的竊聽者能夠存取解密對話所需的密鑰。
- End-to-end encryption (E2EE) is the use of cryptography implemented through the Transport Layer Security protocol (TLS) for the protection of a message so that it can only be read by the communicating users, and not by third parties acting as intermediaries in the transfer of this data.
- End-to-end encryption (E2EE) is a system of communication where only the communicating users can read the messages. In principle, it prevents potential eavesdroppers – including telecom providers, Internet providers, malicious actors, and even the provider of the communication service – from being able to access the cryptographic keys needed to decrypt the conversation.
