Tspi_EncodeDER_TssBTCG(Software	Stack Developer's RefTspi_EncodeDER_TssBlob(3)

NAME
       Tspi_EncodeDER_TssBlob -	generate a DER encoded TSS blob.

SYNOPSIS
       #include	<tss/tspi.h>

       TSS_RESULT Tspi_EncodeDER_TssBlob(UINT32	rawBlobSize, BYTE*   rawBlob,
					 UINT32	blobType,    UINT32* derBlobSize,
					 BYTE*	derBlob);

DESCRIPTION
       Tspi_EncodeDER_TssBlob	is  used to generate a DER-encoded blob	in ac-
       cordance	with the ASN.1 data definitions	in the Portable	 Data  section
       of  the	Trusted	 Computing  Group Software Stack Specification Version
       1.2.

PARAMETERS
   rawBlobSize
       Size of the unwrapped blob.

   rawBlob
       Pointer to the unwrapped	blob.

   blobType
       Type of blob being wrapped (refer to the	TSS_BLOB_TYPE_*	constants).

   derBlobSize
       Pointer to the size of the derBlob buffer.   On	input  this  parameter
       contains	 a pointer to the maximum size of the supplied derBlob buffer.
       On output this parameter	contains a pointer to the actual size  of  the
       DER-encoded  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 DER-encoded blob without writing to the derBlob buffer.

       Note: If	the raw	data blob length is less than 2^16 bytes then the DER-
       encoding	may add	no more	than 20	bytes.

   derBlob
       Pointer to a buffer to hold the DER-encoded 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_EncodeDER_TssBlob conforms to the Trusted Computing	Group Software
       Specification Version 1.2

SEE ALSO
       Tspi_DecodeBER_TssBlob(3).
