Add a context structure for the algorithm and keys established by NTS-KE. Modify the client to save the context and reset the SIV key to the C2S/S2C key before each request/response instead of keeping two SIV instances. This will make it easier for the server to support different algorithms and allow the client to save the context with cookies to disk.
