kandi X-RAY | tpm2-totp Summary

tpm2-totp is a C library. tpm2-totp has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

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. Another addition is the ability to rebind an old secret to the current PCRs in case a software component was changed on purpose, using a user-defined password.

Install tpm2-totp

When the platform is in a known trustworthy state, the user will generate a tpm2-totp secret that is sealed to the current PCR values of the TPM. The secret is also exported (e.g. via QR-Code) so it can be recorded in a TOTP application (e.g. freeotp on Android phones). The secret is also stored inside the TPM's NV space.
Followed by setting up the initrd, see below. Instructions on packages needed to build and install tpm2-totp and different build options are available in the INSTALL file.
The TOTP secret can be generated with and without password. It is recommended to set a password -Pin order to enable recovery options. Also the PCRs and PCR banks can be selected -p and -b. Default values are PCRs 0,2,4 and banks SHA1, SHA256.
