Tspi_D...ssBlob(3)  TCG Software Stack Developer's Reference  Tspi_D...ssBlob(3)

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 con-
     tains a pointer to the maximum size of the  supplied  rawBlob  buffer.   On
     output  this  parameter  contains	a  pointer to the actual size of the un-
     wrapped 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 un-
     wrapped 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
