18 Tspi_EncodeDER_TssBlob is used to generate a DER-encoded blob in ac‐
19 cordance with the ASN.1 data definitions in the Portable Data section
20 of the Trusted Computing Group Software Stack Specification Version
21 1.2.
22
24 rawBlobSize
25 Size of the unwrapped blob.
26
27 rawBlob
28 Pointer to the unwrapped blob.
29
30 blobType
31 Type of blob being wrapped (refer to the TSS_BLOB_TYPE_* constants).
32
33 derBlobSize
34 Pointer to the size of the derBlob buffer. On input this parameter
35 contains a pointer to the maximum size of the supplied derBlob buffer.
36 On output this parameter contains a pointer to the actual size of the
37 DER-encoded 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 DER-encoded blob without writing to the derBlob buffer.
40
41 Note: If the raw data blob length is less than 2^16 bytes then the DER-
42 encoding may add no more than 20 bytes.
43
44 derBlob
45 Pointer to a buffer to hold the DER-encoded 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_EncodeDER_TssBlob conforms to the Trusted Computing Group Software
57 Specification Version 1.2
