ctap

ctap is a library implementing the FIDO2 CTAP protocol.

Usage example

use ctap_hmac::*;
let device_info = get_devices()?.next().expect("no device connected");
let mut device = FidoDevice::new(&device_info)?;

// This can be omitted if the FIDO device is not configured with a PIN.
let pin = "test";
device.unlock(pin)?;

// In a real application these values would come from the requesting app.
let cred_request = FidoCredentialRequestBuilder::default()
                    .rp_id("rp_id")
                    .user_name("user_name")
                    .build().unwrap();

let cred = device.make_credential(&cred_request)?;
let cred = &&cred;
let assertion_request = FidoAssertionRequestBuilder::default()
                            .rp_id("rp_id")
                            .credential(&&cred)
                            .build().unwrap();
// In a real application the credential would be stored and used later.
let result = device.get_assertion(&assertion_request);
