Note: In the above example it is a failure if you finished the attempt (authnAttemptId) already or the authnAttemptId is invalid. Though the /status method is useful if used with the basic initialization request (that is, /initialize followed by /verify).
Generate a Hash-based Message Authentication Code (HMAC) for Authentication Agents
The administrator can generate a Hash-based Message Authentication Code (HMAC) that can be used to encrypt authentication requests between authentication agents and the RSA SecurID Authentication API.
The HMAC provides a hash for the request body and an HMAC signature.
