End-to-End Encryption (E2EE)
End-to-End Encryption (E2EE) is a method of secure communication that prevents third-parties from accessing data while it’s transferred from one end system or device to another.
The data is encrypted on the sender’s system or device and only the recipient is able to decrypt it. The information is rendered unreadable to anyone else who might intercept the data while it’s in transit. E2EE is commonly used in messaging apps, email services, and file storage solutions to protect user data from unauthorized access.
One of the main benefits of E2EE is that even the service provider does not have access to the unencrypted data, ensuring the highest level of privacy for the users. However, this also means that if the user loses the decryption key, the data cannot be recovered.
Implementing E2EE involves generating a pair of cryptographic keys, a public key, and a private key. The public key is used to encrypt the data, and the private key is used to decrypt it. The private key is kept secret and only known to the recipient.
