You can use the raw shared secret that DeriveSharedSecret returns to derive a symmetric key that can encrypt and decrypt data that is sent between the two peers, or that can generate and verify HMACs.

The public key can be from another asymmetric KMS key pair or from a key pair generated outside of KMS, but both key pairs must be on the same elliptic curve.</p>
