What Is End2End Encryption, and Why Does It Matter?
End-to-end encryption (E2EE) ensures that your data is encrypted (kept secret) until it reaches an intended recipient. Whether you’re talking about end-to-end encrypted messaging, email, file storage, or anything else, this ensures that no one in the middle can see your private data.
In other words: If a chat app offers end-to-end encryption, for example, only you and the person you’re chatting with will be able to read the contents of your messages. In this scenario, not even the company operating the chat app can see what you’re saying.
