NAME

       Tspi_DAA_IssueInit - initialize the Issuer for a join operation

SYNOPSIS

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

       TSPICALL Tspi_DAA_IssueInit(
	   TSS_HDAA			 hDAA,
	   TSS_HKEY			 issuerAuthPK,
	   TSS_HKEY			 issuerKeyPair,
	   TSS_DAA_IDENTITY_PROOF	 identityProof,
	   UINT32			 capitalUprimeLength,
	   BYTE*			 capitalUprime,
	   UINT32			 daaCounter,
	   UINT32*			 nonceIssuerLength,
	   BYTE**			 nonceIssuer,
	   UINT32*			 authenticationChallengeLength,
	   BYTE**			 authenticationChallenge,
	   TSS_DAA_JOIN_ISSUER_SESSION*  joinSession
       );

DESCRIPTION

       Tspi_DAA_IssueInit is a function that is part of the DAA Issuer component. It's the first function out of 2 in order to issue a DAA Creden-
       tial for a TCG Platform. It assumes that the endorsement key and its associated credentials are from a genuine and valid TPM. (Verification
       of the credentials is a process defined by the TCG Infrastructure WG.)

PARAMETERS

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

   issuerAuthPK
       The issuerAuthPKh parameter is the root authentication (public) key of DAA Issuer.

   issuerKeyPair
       The issuerKeyPair parameter is the handle of the main DAA Issuer key pair (private and public portion).

   identityProof
       The identityProof parameter is the structure containing endorsement, platform and conformance credential of the TPM requesting the DAA Cre-
       dential.

   capitalUprimeLength
       The capitalUprimeLength parameter is the length of capitalUprime which is .

   capitalUprime
       The capitalUprime parameter is U'.

   daaCounter
       The daaCounter parameter is the DAA counter.

   nonceIssuerLength
       The nonceIssuerLength parameter is the length of nonceIssuer (20 bytes).

   nonceIssuer
       The nonceIssuer parameter is the nonce of the DAA Issuer.

   authenticationChallengeLength
       The authenticationChallengeLength parameter is the length of authenticationChallenge (256 bytes - DAA_SIZE_NE1).

   authenticationChallenge
       The authenticationChallenge parameter is the second nonce of the DAA Issuer that is encrypted by the endorsement public key. It is used	as
       a challenge to authenticate the TPM.

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

RETURN CODES

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

       TSS_E_INVALID_HANDLE
	      Either the DAA is not valid.

       TSS_E_BAD_PARAMETER

       TSS_E_INTERNAL_ERROR
	      An internal SW error has been detected.

CONFORMING TO

       Tspi_DAA_IssueInit conforms to the Trusted Computing Group Software Specification version 1.2

NAME

       Tspi_Context_LoadKeyByBlob - load a key into the TPM using the key's blob.

SYNOPSIS

       #include <tss/platform.h>
       #include <tss/tcpa_defines.h>
       #include <tss/tcpa_typedef.h>
       #include <tss/tcpa_struct.h>
       #include <tss/tss_typedef.h>
       #include <tss/tss_structs.h>
       #include <tss/tspi.h>

       TSS_RESULT Tspi_Context_LoadKeyByBlob(TSS_HCONTEXT hContext,	TSS_HKEY hUnwrappingKey,
					     UINT32	  ulBlobLength, BYTE*	 rgbBlobData,
					     TSS_HKEY*	  phKey);

DESCRIPTION

       Tspi_Context_LoadKeyByBlob creates a key based on the information gotten by the key blob. It then loads the key into the TPM, which unwraps
       the key blob by using the key associated with hUnwrappingKey. The key blob addressed by hUnwrappingKey must have been already  loaded  into
       the TPM. This function returns a handle to the created key object.

PARAMETERS

   hContext
       The hContext parameter is the handle of the context object.

   hUnwrappingKey
       The  hUnwrappingKey parameter is the handle of the key object which should be used to unwrap the key information associated with rgbBlobDa-
       ta.

   rgbBlobData
       The rgbBlobData parameter is the wrapped key to load.

   phKey
       The phKey parameter receives the handle of the key object representing the loaded key.

RETURN CODES

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

       TSS_E_INVALID_HANDLE
	      hContext is not a valid handle.

       TSS_E_INTERNAL_ERROR
	      An internal SW error has been detected.

       TSS_E_BAD_PARAMETER
	      One or more parameters is bad.

CONFORMING TO

       Tspi_Context_LoadKeyByBlob conforms to the Trusted Computing Group Software Specification version 1.1 Golden
