How does public / private key encryption work.

A user is generated two keys, one public and one private, in public key cryptography. The public key is freely sharable to the public and is used to encrypt messages. Only the owner of the private key is aware of the private key, and it is used to decrypt messages.

To send a message, the sender encrypts it using the recipient's public key. The recipient then decrypts the message using their private key. Because an attacker cannot decrypt a message without knowing the private key, public key cryptography is more secure than traditional cryptography.

Nomie 6's new Cloud Storage service encrypts your data on your device BEFORE it is sent to the server using public / private key encryption. Once on the server, it is unreadable gibberish until it is downloaded to the device and decrypted for reading.
