This is a reimplementation of Matthew Garrett's tpmtotp
software for TPM 2.0 using the tpm2-tss software stack. Its
purpose is to attest the trustworthiness of a device against
a human using time-based one-time passwords (TOTP),
facilitating the Trusted Platform Module (TPM) to bind the
TOTP secret to the known trustworthy system state. In
addition to the original tpmtotp, given the new capabilities
of in-TPM hmac calculation, the tpm2-totp's secret HMAC keys
do not have to be exported from the TPM to the CPU's RAM on
boot anymore.
