"End-to-end encryption" provides a communication framework where only the communicating users can read the messages. This means that no third party, including service providers or potential eavesdroppers, can access or decrypt the information shared. By ensuring that data is encrypted on the sender's device and decrypted only on the recipient's device, end-to-end encryption enhances privacy and security. It is widely used in messaging applications and email services to protect personal conversations and sensitive information.
