Encryption from sender to recipient without exposure on intermediate servers.
End to End Encryption Definition: Encryption from sender to recipient without exposure on intermediate servers.
End-to-End Encryption E2EE is a communication method where data is encrypted on the sender's device and can only be decrypted by the intended recipient. No intermediate node, including internet service providers or application servers, has access to the unencrypted data. E2EE is commonly used in messaging applications and secure communications platforms to ensure confidentiality. For example, apps like Signal or WhatsApp use end-to-end encryption to protect user messages from interception.
