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