- Receiver loads the EC key (public/private/curve)
- Receiver sends its public key and curve to the Transmitter
- Transmitter generates a new ephemeral EC key on the curve
- Transmitter generates the shared symmetric key
- Transmitter encrypts the data and sends its public key and ciphertext to the Receiver
- Receiver generates the shared symmetric key
- Receiver descrypts the data
