6.8 SelfTest Command
    The SelfTest command performs on-demand testing of one
            or more of the cryptographic algorithms implemented in the TA010-TFLXAUTH. The algorithms HMAC (SHA-256), ECDSA and the DRBG of the RNG each
            have a self-test routine to confirm their integrity. The SelfTest
            command can be run at any time after the initial start-up procedure is completed.
