Tspi_EncodeDER_TssBlob(3)			     TCG Software Stack Developer's Reference				 Tspi_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 accordance 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

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
