🎀 NAME 🎀

Tspi_DAA_VerifyInit — creates a challenge for the TCG platform 🦋

🌸 SYNOPSIS 🌸

#include <tss/tss_typedef.h>
#include <tss/tss_structs.h>
#include <tss/tspi.h>

TSPICALL Tspi_DAA_VerifyInit(
    TSS_HDAA                    hDAA,
    UINT32*                     nonceVerifierLength,
    BYTE**                      nonceVerifier,
    UINT32*                     baseNameLength,
    BYTE**                      baseName
);

✨ DESCRIPTION ✨

So Tspi_DAA_VerifyInit is part of the DAA Verifier component 🫶. It's the first function out of 2 in order to verify a DAA Credential of a TCG platform. Its whole main-character job? It creates a challenge for the TCG platform ⭐.

This is an optional function, and — important vibe check — it does not require a TPM or a TCS 😌. No extra hardware drama, periodt.

💡 Optional, no TPM, no TCS — that's the whole note, bestie.
