SignResponseData

AI-generated Key Takeaways

• The SignResponseData class is deprecated and users should use Fido APIs instead.

• This class is a utility for producing a U2F SignResponse object.

• Example code demonstrates how to handle SignResponseData within onActivityResult.

• The class includes constants for JSON keys like "clientData", "keyHandle", and "signatureData".

• Public methods are available for accessing client data string, key handle, signature data, and converting to a JSONObject.

public class SignResponseData extends ResponseData

This class is deprecated.
Please use Fido APIs instead.

A utility class to produce a U2F SignResponse object.

Example of handling response data:

 @Override
 protected void onActivityResult(int requestCode, int resultCode, Intent data) {
   if (resultCode != RESULT_OK) {
     // Something went wrong
   }

   switch(requestCode) {
     case REGISTER_REQUEST_CODE:
       RegisterResponseData registerResponse = (RegisterResponseData) data
           .getParcelableExtra(Fido.KEY_RESPONSE_EXTRA);
       // Do something useful
       break;
     case SIGN_REQUEST_CODE:
       SignResponseData signResponse = (SignResponseData) data
           .getParcelableExtra(Fido.KEY_RESPONSE_EXTRA);
       // Do something useful
       break;
     default:
       // Something went wrong
   }
 }
