Encryption

This document explains how to encrypt data.

To encrypt data, use the encrypt method from the FheEncrypt trait. This crate provides types that implement either FheEncrypt or FheTryEncrypt or both, to enable encryption.

Here is an example:

use tfhe::prelude::*;
use tfhe::{generate_keys, ConfigBuilder, FheUint8};

fn main() {
    let config = ConfigBuilder::default().build();

    let (client_key, server_key) = generate_keys(config);

    let clear_a = 27u8;
    let clear_b = 128u8;

    let a = FheUint8::encrypt(clear_a, &client_key);
    let b = FheUint8::encrypt(clear_b, &client_key);
}
