NAME

       Tspi_DecodeBER_TssBlob - unwraps a BER-encoded TSS blob.

SYNOPSIS

       #include <tss/tspi.h>

       TSS_RESULT Tspi_DecodeBER_TssBlob(UINT32  berBlobSize, BYTE*   berBlob,
					 UINT32* blobType,    UINT32* rawBlobSize,
					 BYTE*	 rawBlob);

DESCRIPTION

       Tspi_DecodeBER_TssBlob	is used to unwrap a BER-encoded blob in accordance with the ASN.1 data definitions in the Portable Data section of
       the Trusted Computing Group Software Stack Specification Version 1.2.

PARAMETERS

   berBlobSize
       Size of the BER-encoded blob.

   berBlob
       Pointer to the BER-encoded blob.

   blobType
       Pointer to the type of blob being unwrapped (refer to the TSS_BLOB_TYPE_* constants).

   rawBlobSize
       Pointer to the size of the rawBlob buffer.  On input this parameter contains a pointer to the maximum size of the supplied rawBlob  buffer.
       On  output this parameter contains a pointer to the actual size of the unwrapped blob.  On input, if this parameter points to a value of 0,
       then this function will return the size of the buffer required to hold the unwrapped blob without writing to the rawBlob buffer.

       Note: The output data must be shorter than the BER-encoding, so berBlobSize is a useful upper limit on rawBlob buffer size.

   rawBlob
       Pointer to a buffer to hold the unwrapped blob.

RETURN CODES

       Tspi_EncodeDER_TssBlob returns TSS_SUCCESS on success, otherwise one of the following values are returned:

       TSS_E_BAD_PARAMETER

       TSS_E_INTERNAL_ERROR - An error occurred internal to the TSS.

CONFORMING TO

       Tspi_DecodeBER_TssBlob conforms to the Trusted Computing Group Software Specification Version 1.2

NAME

       Tspi_Key_CreateMigrationBlob - create a key blob suitable for migrating to another TPM.

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_Key_CreateMigrationBlob(TSS_HKEY hKeyToMigrate,		TSS_HKEY hParentKey,
					       UINT32	ulMigTicketLength,	BYTE*	 rgbMigTicket,
					       UINT32*	pulRandomLength,	BYTE**	 prgbRandom,
					       UINT32*	pulMigrationBlobLength, BYTE**	 prgbMigrationBlob);

DESCRIPTION

       Tspi_Key_CreateMigrationBlob  returns a key blob containing an encrypted section, which will be different depending on the migration scheme
       indicated within the migration ticket previously created by the method Tspi_TPM_AuthorizeMigrationTicket().

PARAMETERS

   hKeyToMigrate
       Handle of the key object to migrate.

   hParentKey
       Handle to the parent key related to the key addressed by hKeyToMigrate.

   ulMigTicketLength
       The length (in bytes) of the rgbMigTickey parameter.

   rgbMigTicket
       Pointer to memory containing the migration ticket (migration public key and its authorization digest).

   pulRandomLength
       On successful completion this parameter returns the random data length returned at the parameter prgbRandom.

   prgbRandom
       On successful completion this parameter returns the random data.

   pulMigrationBlobLength
       On successful completion this parameter returns the length of the migration blob data returned at the parameter prgbMigrationBlob.

   prgbMigrationBlob
       On successful completion this parameter returns the migration data blob.

RETURN CODES

       Tspi_Key_CreateMigrationBlob returns TSS_SUCCESS on success, otherwise one of the following values are returned:

       TSS_E_INVALID_HANDLE - Either hKeyToMigrate, hParentKey or rgbMigTicket are invalid parameters.

       TSS_E_BAD_PARAMETER - One of the passed parameters is wrong.

       TSS_E_KEY_NO_MIGRATION_POLICY - No migration policy picked.

       TSS_E_INTERNAL_ERROR - An error occurred internal to the TSS.

CONFORMING TO

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