I am new using the library and I wonder if there is any method to serialize and display the information of a ciphertext by console in order to save it in a database. I have seen that there is the SerializeToFile method to save the ciphertext in a file, is there another one to save it in a variable …

Hi, there are a couple of ways to do matrix vector and matrix matrix operations in the literature, most trade efficiency for complexity in implementation. We eventually plan to release a sub-library for this, but it won’t be available in the short term. In response to the question of how to encrypt…

Hi, this is a common question, you may want to review some of the existing library questions. by design a ciphertext is encrypted data. so not sure what you want to look at. A ciphertext is a C++ object. It can be serialized to a binary buffer or a json string using the Serialize method and both c…

Thank you very much for your reply. Could you explain this in more depth? Does this mean that all libraries using BGV, BFV and CKKS will generate a long ciphertext? [image] dcousins: Also remember that for the BGV,BFV,CKKS family of schemes, CT can most efficiently contain a vector of data, an…

@dcousins sorry, I didn’t mention you

@dcousins I have read the post but it is not exactly what I would like to know. Like you said in your first answer: CT can be serialized to a binary buffer or a json string using the Serialize method and both could be written directy to files using the method you pointed out. Both will be very, ve…

@jtovartr There’s a bit of nuance here that might go over your head (especially as a newbie). Say we have the following dataset: X = [ [ 0, 1, 2, 3], [ 4, 5, 6, 7], [ 8, 9, 10, 11], [12, 13, 14, 15], [16, 17, 18, 19] ]) Two things to keep in mind: Oftentimes, we have m…

when you select all the paramters for a scheme, you will get a resutling ciphertext size. it is based on how much computation (multiplicative depth) you want to do before bootstrapping, as well as security settings. you can easily determine the size of a Ciphertext by serializing it to file or to …

Thank you very much for explaining it to me in more detail, now I understand it better.

The main objective, as you say, is to encrypt data, store them in a database and be able to retrieve these encrypted data to be able to apply different operations on them, such as addition, multiplication, calculation of averages, obtaining statistics of the encrypted data. And in the future, be ab…

@iquah I am thinking about the information you provided me and I want to pass the following example to real code, but how can I encrypt a matrix or a vector of vectors like the example you provided me? [image] iquah: X = [ [ 0, 1, 2, 3], [ 4, 5, 6, 7], [ 8, 9, 10, 11], [1…

yes, while you can encrypt a single value, each of those schemes supports encrypting a vector. See @Caesar 's post Is there a limit to plaintext size? for a good discussion.
