TLSSocket.prototype.getEphemeralKeyInfo(): EphemeralKeyInfo
 | object
 | null

Returns an object representing the type, name, and size of parameter of an ephemeral key exchange in perfect forward secrecy on a client connection. It returns an empty object when the key exchange is not ephemeral. As this is only supported on a client socket; null is returned if called on a server socket. The supported types are 'DH' and 'ECDH'. The name property is available only when type is 'ECDH'.

For example: { type: 'ECDH', name: 'prime256v1', size: 256 }.
