Key Generation

Once you've created a runtime, generating keys is simple:

use sunscreen::{
    fhe_program,
    types::{bfv::Signed, Cipher},
    Compiler, Runtime, PublicKey
};

#[fhe_program(scheme = "bfv")]
fn noop() {
}

fn main() {
   let fhe_program = Compiler::with_fhe_program(noop)
       .compile()
       .unwrap();

   let runtime = Runtime::new(&fhe_program.metadata.params).unwrap();

    let (public_key, private_key) = runtime.generate_keys().unwrap();
}

This produces a public key (which allows you to encrypt data and run FHE programs) and a private key (which allows you to decrypt).
