Adding Paillier Context to encrypted number serialisation in CLI #37
Description
Paillier Context is included in the encrypted number in the backend, but CLI doesn't include Paillier Context when serialising encrypted number. Currently this is not a problem because Paillier Context is not configurable from the CLI. (The required Paillier Context can be derived if a correct public key is provided.) However, if Paillier Context can be configured from CLI, then it needs to be included in encrypted number serialisation.
