19 Tspi_TPM_CMKSetRestrictions is used to set restrictions on the delegat‐
20 ed use of Certified Migratable Keys (CMKs). Use of this command cannot
21 itself be delegated.
22
23
25 hTPM
26 The hTPM parameter is used to specify the handle of the TPM object.
27
28 CmkDelegate
29 The CmkDelegate parameter is a bitmask describing the kinds of CMKs
30 that can be used in a delegated auth session. Each bit represents a
31 type of key. If the bit of a key type is set, then the CMK can be used
32 in a delegated authorization session, otherwise use of that key will
33 result in a TPM_E_INVALID_KEYUSAGE return code from the TPM.
34
35 The possible values of CmkDelegate are any combination of the following
36 flags logically OR'd together:
37
38
39 TSS_CMK_DELEGATE_SIGNING
40 Allow use of signing keys.
41
42
43 TSS_CMK_DELEGATE_STORAGE
44 Allow use of storage keys.
45
46
47 TSS_CMK_DELEGATE_BIND
48 Allow use of binding keys.
49
50
51 TSS_CMK_DELEGATE_LEGACY
52 Allow use of legacy keys.
53
54
55 TSS_CMK_DELEGATE_MIGRATE
56 Allow use of migratable keys.

58
60 Tspi_TPM_CMKSetRestrictions returns TSS_SUCCESS on success, otherwise
61 one of the following values is returned:
62
63 TSS_E_INVALID_HANDLE
64 hTPM is not a valid handle.
65
66
67 TSS_E_INTERNAL_ERROR
68 An internal SW error has been detected.
