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
