Encryption using server keys about concrete HOT 2 CLOSED

Hello @julen-bernabe !

What you describe is not achievable with server keys, however it is doable with what is known as a public key. We are currently repackaging some code in the new TFHE-rs project you can find here : https://github.com/zama-ai/tfhe-rs you can check for example the docs.rs page for the shortint public key https://docs.rs/tfhe/0.1.5/tfhe/shortint/public_key/struct.PublicKey.html and the user docs md from the repo : https://github.com/zama-ai/tfhe-rs/blob/main/tfhe/docs/shortint/tutorial.md#encrypting-values-using-a-public-key (and boolean: https://github.com/zama-ai/tfhe-rs/blob/main/tfhe/docs/Booleans/tutorial.md#encrypting-inputs-using-a-public-key). The server key requirement for shortint will be removed (it had to do with noise management).

Do note that we are aware of key size issues with the larger parameters sets for shortint and are currently working to resolve them.

If you have any other question feel free to ask them here 🙂
