Tspi_DecodeBER_TssBlob(3) TCG Software Stack Developer's Reference Tspi_DecodeBER_TssBlob(3) 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 SEE ALSO
