EndezuEndeverschlüsselte

Ende-zu-Ende-Verschlüsselung, often abbreviated as E2EE, is a method of secure communication that ensures only the communicating users can read the messages. It works by encrypting data on the sender's device and decrypting it only on the recipient's device. This means that the data is unreadable to any third party, including the service provider hosting the communication.

The process typically involves public-key cryptography. When a user initiates an E2EE communication, their device generates a pair of cryptographic keys: a public key and a private key. The public key can be shared with anyone and is used to encrypt messages intended for that user. The private key, however, is kept secret by the user and is the only key capable of decrypting messages encrypted with the corresponding public key.

When User A wants to send an E2EE message to User B, User A's device encrypts the message using User B's public key. This encrypted message is then sent to User B's device. Upon receiving the encrypted message, User B's device uses their private key to decrypt it, making the original message readable.

This form of encryption is widely used in messaging applications, email services, and other communication platforms to protect user privacy and data security. It prevents eavesdropping and ensures that sensitive information remains confidential throughout its transmission.
