9 tss2_createseal [OPTIONS]
10
12 tss2_createseal(1) - This command creates a sealed object and stores it
13 in the FAPI metadata store. If no data is provided (i.e. a NULL-point‐
14 er) then the TPM generates random data and fills the sealed object.
15
17 These are the available options:
18
19 · -p, --path STRING:
20
21 The path to the new key.
22
23 · -t, --type STRING:
24
25 Identifies the intended usage. Optional parameter. Types may be any
26 comma-separated combination of:
27
28 - "exportable": Clears the fixedTPM and fixedParent attributes of a key or
29 sealed object.
30 - "noda": Sets the noda attribute of a key or NV index.
31 - "system": Stores the data blobs and metadata for a created key or seal
32 in the system-wide directory instead of user's personal directory.
33 - A hexadecimal number (e.g. "0x81000001"): Marks a key object to be
34 made persistent and sets the persistent object handle to this value.
35
36 · -P, --policyPath STRING:
37
38 Identifies the policy to be associated with the new key. Optional
39 parameter. If omitted then no policy will be associated with the
40 key.
41
42 A policyPath is composed of two elements, separated by “/”. A poli‐
43 cyPath starts with “/policy”. The second path element identifies the
44 policy or policy template using a meaningful name.
45
46 · -a, --authValue STRING:
47
48 The new UTF-8 password. Optional parameter. If it is neglected then
49 the user is queried interactively for a password. To set no pass‐
50 word, this option should be used with the empty string ("").
51
52 · -i, --data FILENAME or - (for stdin):
53
54 The data to be sealed by the TPM. Optional parameter.
55
57 This collection of options are common to all tss2 programs and provide
58 information that many users may expect.
59
60 · -h, --help [man|no-man]: Display the tools manpage. By default, it
61 attempts to invoke the manpager for the tool, however, on failure
62 will output a short tool summary. This is the same behavior if the
63 “man” option argument is specified, however if explicit “man” is re‐
64 quested, the tool will provide errors from man on stderr. If the
65 “no-man” option if specified, or the manpager fails, the short op‐
66 tions will be output to stdout.
67
68 To successfully use the manpages feature requires the manpages to be
69 installed or on MANPATH, See man(1) for more details.
70
71 · -v, --version: Display version information for this tool, supported
72 tctis and exit.
73
75 Create a key with password “abc” and read sealing data from file.
76 tss2_createseal --path HS/SRK/mySealKey --type "noDa" --authValue abc --data data.file
77
79 0 on success or 1 on failure.
