Crate ctaphid

Communicate with devices implementing the CTAPHID protocol.

This implementation is based on the FIDO Client to Authenticator Protocol (CTAP) specification (version of June 15, 2021), section 11.2.

Quickstart

let hidapi = hidapi::HidApi::new()?;
let devices = hidapi.device_list().filter(|device| ctaphid::is_known_device(*device));
for device_info in devices {
    let hid_device = device_info.open_device(&hidapi)?;
    let device = ctaphid::Device::new(hid_device, device_info.to_owned())?;
    print!(
        "Trying to ping CTAPHID device 0x{:x}:0x{:x} ...",
        device_info.vendor_id(),
        device_info.product_id(),
    );
    device.ping(&[0xde, 0xad, 0xbe, 0xef])?;
    println!("done");
}
