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
