createPacketCipher(
    cipher: string,
    mac: string,
    keys: DirectionKeys,
): Promise<PacketCipher>
Builds a PacketCipher for one direction from the negotiated algorithm names and the derived key material.
Parameters
- cipher: string
  The negotiated encryption algorithm name.
- mac: string

- keys: DirectionKeys
  The per-direction key/IV/MAC material from the key schedule.
Returns Promise<PacketCipher>
