18 Tspi_DecodeBER_TssBlob is used to unwrap a BER-encoded blob in accor‐
19 dance with the ASN.1 data definitions in the Portable Data section of
20 the Trusted Computing Group Software Stack Specification Version 1.2.
21
23 berBlobSize
24 Size of the BER-encoded blob.
25
26 berBlob
27 Pointer to the BER-encoded blob.
28
29 blobType
30 Pointer to the type of blob being unwrapped (refer to the
31 TSS_BLOB_TYPE_* constants).
32
33 rawBlobSize
34 Pointer to the size of the rawBlob buffer. On input this parameter
35 contains a pointer to the maximum size of the supplied rawBlob buffer.
36 On output this parameter contains a pointer to the actual size of the
37 unwrapped blob. On input, if this parameter points to a value of 0,
38 then this function will return the size of the buffer required to hold
39 the unwrapped blob without writing to the rawBlob buffer.
40
41 Note: The output data must be shorter than the BER-encoding, so
42 berBlobSize is a useful upper limit on rawBlob buffer size.
43
44 rawBlob
45 Pointer to a buffer to hold the unwrapped blob.
46
48 Tspi_EncodeDER_TssBlob returns TSS_SUCCESS on success, otherwise one of
49 the following values are returned:
50
51 TSS_E_BAD_PARAMETER
52
53 TSS_E_INTERNAL_ERROR - An error occurred internal to the TSS.
54
56 Tspi_DecodeBER_TssBlob conforms to the Trusted Computing Group Software
57 Specification Version 1.2
58
60 Tspi_DecodeBER_TssBlob(3).
