20 Tspi_TPM_GetAuditDigest is used to retrieve the audit digest. The au‐
21 dit digest may be signed or unsigned. If the audit digest is signed
22 (hKey is non-NULL) then the current audit digest, the current audit
23 counter and, optionally, the hash of the audited ordinal list and a
24 signature are returned. If the audit digest is not signed (hKey is
25 NULL) then the current audit digest, the current audit counter and the
26 full list of audited ordinals is returned.
27
29 hTpm
30 Handle of the TPM object.
31
32 hKey
33 Handle of the signature key object (the handle can be NULL).
34
35 closeAudit
36 A flag indicating whether or not to close the current audit digest af‐
37 ter it is signed. This parameter is ignored if hKey is NULL.
38
39 pulAuditDigestSize
40 Pointer to the size of the returned audit digest.
41
42 prgbAuditDigest
43 Pointer to a buffer that holds the returned audit digest.
44
45 pCounterValue
46 Pointer to a TPM_COUNTER_VALUE structure that holds the returned audit
47 counter.
48
49 pValidationData
50 Pointer to a validation data structure. The validation data structure
51 provides external information required to compute the signature. On
52 input, the fields representing the ExternalData must contain an anti-
53 replay nonce that will be used in the signing operation. On output,
54 this structure provides a buffer containing the data used to compute
55 the validation data and a buffer containing the validation data (a sig‐
56 nature generated by signing the data using the key referenced by hKey).
57 If this parameter is NULL then the TSS will perform the validation.
58 This parameter is ignored if hKey is NULL.
59
60 ordSize
61 Pointer to the number of ordinals in the returned audited ordinal list.
62 This parameter is ignored if hKey is non-NULL.
63
64 ordList
65 Pointer to a buffer that holds the returned audited ordinal list. This
66 parameter is ignored if hKey is non-NULL.
67
69 Tspi_TPM_GetAuditDigest returns TSS_SUCCESS on success, otherwise one
70 of the following values are returned:
71
72 TSS_E_INVALID_HANDLE
73
74 TSS_E_BAD_PARAMETER
75
76 TSS_E_INTERNAL_ERROR - An error occurred internal to the TSS.
