Hi, I have a question about creating a Ctxt array. Which one should I choose (which is faster or more reasonable in ciphertext operations?): ``` Ctxt* ctxt1 = new Ctxt(publicKey,...

Hi team, I'm studying the CKKS scheme and wondering how does the `rescale` part work in the CKKS of HElib. If it's possible to modify it by ourselves? Similar question...

Hi, I have a question, when I generate a new context by reading from stringstream, these two context should be equal. But if I encrypt the vector using the oldContext.publickey,...

Sorry, @fionser I closed the issue in SEAL. My question is: I want to get the exact number of slots in the ciphertext to get a cyclic rotation. Or implement...
