💖 Tspi_TPM_DAA_JoinStoreCredential 💖

Okay bestie, welcome to this page from the Library Functions Manual — also known from the TCG Software Stack Developer's Reference — page Tspi_TPM_D...Credential(3). The main character is Tspi_TPM_DAA_JoinStoreCredential, and yes, she is iconic. ✨

🌸 NAME 🌸

Tspi_TPM_DAA_JoinStoreCredential — compute the final DAA Credential. 💅

🦋 SYNOPSIS 🦋

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

TSS_RESULT Tspi_TPM_DAA_JoinStoreCredential(
    TSS_HDAA                    hDAA,
    TSS_HTPM                    hTPM,
    TSS_DAA_CRED_ISSUER         credIssuer,
    TSS_DAA_JOIN_SESSION        joinSession,
    TSS_HKEY*                   hDaaCredential
);

✨ DESCRIPTION ✨

So Tspi_TPM_DAA_JoinStoreCredential is the last out of 3 functions (after Tspi_TPM_DAA_JoinInit() and Tspi_TPM_DAA_JoinCreateDaaPubKey()) to execute in order to receive a DAA Credential. 🫶 It verifies the issued credential from the DAA Issuer and computes the final DAA Credential. No cap, that's the whole glow-up. 🔥

👑 PARAMETERS 👑

hDAA

The hDAA parameter is used to specify the handle of the DAA object. 🎀

hTPM

The hTPM parameter is the handle to the TPM object. 💖

credIssuer

The credIssuer parameter is the DAA Credential issued by the DAA Issuer including proof of correctness. 🦋

joinSession

The joinSession parameter is the structure containing the DAA Join session information. 🌸

hDaaCredential

The hDaaCredential parameter is the handle of the received DAA Credential. 👑

💀 RETURN CODES 💀

Tspi_TPM_DAA_JoinStoreCredential returns TSS_SUCCESS on success, otherwise one of the following values is returned:

• TSS_E_INVALID_HANDLE — either the DAA or the TPM handler is not valid. 😭
• TSS_E_BAD_PARAMETER — this code is listed here, bestie; the page doesn't give it an extra description. 🙈
• TSS_E_INTERNAL_ERROR — an internal SW error has been detected. 💀
• TSS_E_DAA_CREDENTIAL_PROOF_ERROR — one of the verification of the issued credential failed. 🫠

🌈 CONFORMING TO 🌈

Tspi_TPM_DAA_JoinStoreCredential conforms to the Trusted Computing Group Software Specification version 1.2. ⭐
