use tfhe::prelude::*;
use tfhe::{
    generate_keys, set_server_key, ConfigBuilder, FheAsciiString, FheStringLen,
};
    
fn main() -> Result<(), Box<dyn std::error::Error>> {
    
    let config = ConfigBuilder::default().build();
    let (client_key, server_key) = generate_keys(config);
    set_server_key(server_key);
    
    let string1 = FheAsciiString::try_encrypt("tfhe-RS", &client_key).unwrap();
    let string2 = FheAsciiString::try_encrypt("TFHE-rs", &client_key).unwrap();
    let is_eq = string1.eq_ignore_case(&string2);

    assert!(is_eq.decrypt(&client_key));

    Ok(())
}
