Tspi_EncodeDER_TssBlob - generate a DER encoded TSS blob.

Tspi_EncodeDER_TssBlob conforms to the Trusted Computing Group Software Specification Version 1.2

Tspi_EncodeDER_TssBlob   is used to generate a DER-encoded blob in accordance with the ASN.1 data defini‐
       tions in the Portable Data section of the Trusted Computing Group Software  Stack  Specification  Version
       1.2.

       Tspi_EncodeDER_TssBlob - generate a DER encoded TSS blob.

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.

Tspi_EncodeDER_TssBlob returns TSS_SUCCESS on success, otherwise one of  the  following  values  are  re‐
       turned:

       TSS_E_BAD_PARAMETER

       TSS_E_INTERNAL_ERROR - An error occurred internal to the TSS.

Tspi_DecodeBER_TssBlob(3).
