I can see that there are keyswitchgen procedure in Key.cpp and keyswtiching.cpp but where is the keyswtich procedure??? How do I actually do the keyswitching ??

I'm considering the same question now. And I would like to ask about the meaning of key-switching procedure step2-1 "zero-padding and split" in paper "Better Bootstrapping for Approximate Homomorphic Encryption". I understood the RNS-desompose part but why we have to do the "zero-padding and split" (especially "split")?

I also have the same question. How can I actually do the keyswitching?
