ClientData

Page Summary

The ClientData class is deprecated and users should use Fido APIs instead.
ClientData is sent from the FIDO Client to the relying party and its hash is used for signature verification on registration and authentication responses.
The registration and authentication request messages contain a challenge parameter which is a hash of stringified JSON data that the FIDO client prepares.
The FIDO Client must send ClientData to the relying party during verification so the challenge can be regenerated for signature verification.

public class ClientData extends Object

This class is deprecated.
Please use Fido APIs instead.

ClientData is sent from the FIDO Client to the relying party, and its hash will be sent back from the relying party to the Client for verifying the signature on both registration and authentication responses.

The registration and authentication request messages contain a challenge parameter, which is defined as the SHA-256 hash of a (UTF8 representation of a) stringified JSON data structure that the FIDO client has to prepare. The FIDO Client must send the Client Data to the relying party during the verification phase, where the relying party can regenerate the challenge parameter (by hashing the client data), which is necessary in order to verify the signature both on the registration response message and authentication response message.
