Tspi_DecodeBER_TssBlob (3) - Linux Manuals
Tspi_DecodeBER_TssBlob: unwraps a BER-encoded TSS blob.
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.
