Tspi_TPM_DAA_JoinStoreCredential - compute the final DAA Credential

 #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  ");" 

\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.

The hDAA parameter is used to specify the handle of the DAA object. The hTPM parameter is the handle to the TPM object. The credIssuer parameter is the DAA Credential issued by the DAA Issuer including proof of correctness. The joinSession parameter is the structure containing the DAA Join session information. The hDaaCredential parameter is the handle of the received DAA Credential.

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

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

Tspi_TPM_DAA_JoinStoreCredential conforms to the Trusted Computing Group Software Specification version 1.2
