SYNOPSIS

9       tss2_createnv [OPTIONS]
10

SEE ALSO

12       fapi-config(5)  to  adjust  Fapi parameters like the used cryptographic
13       profile and TCTI or directories for the Fapi metadata storages.
14
15       fapi-profile(5) to determine the cryptographic algorithms  and  parame‐
16       ters for all keys and operations of a specific TPM interaction like the
17       name hash algorithm, the asymmetric signature algorithm, scheme and pa‐
18       rameters and PCR bank selection.

DESCRIPTION

21       tss2_createnv(1) - This command creates an NV index in the TPM.
22

OPTIONS

24       These are the available options:
25
26-p, --path=STRING:
27
28         Path of the new NV space.
29
30         The  path is composed of three elements, separated by “/”.  An nvPath
31         starts with “/nv”.  The second path element identifies the NV  handle
32         range  for the nv object.  This includes the following values: Owner,
33         TPM, Platform, Endorsement_Certificate, Platform_Certificate,  Compo‐
34         nent_OEM, TPM_OEM, Platform_OEM, PC-Client, Server, Virtualized_Plat‐
35         form, MPWG, Embedded.  The third path element identifies  the  actual
36         NV-Index using a meaningful name.
37
38-t, --type=STRING:
39
40         Identifies the intended usage.  Optional parameter.  Types may be any
41         comma-separated combination of:
42
43                - "noda": Sets the noda attribute of a key or NV index.
44                - "bitfield": Sets the NV type to bitfield.
45                - "counter": Sets the NV type to counter.
46                - "pcr": Sets the NV type to pcr-like behavior.
47                - Hint: If none of the previous three keywords is provided a regular NV
48                  index is created.
49
50-s, --size=INTEGER:
51
52         The size in bytes of the NV index to be created.  Can be  omitted  if
53         size  can be inferred from the type; e.g. an NV index of type counter
54         has a size of 8 bytes.
55
56-P, --policyPath=STRING:
57
58         Identifies the policy to be associated with the new  NV  space.   Op‐
59         tional  parameter.  If omitted then no policy will be associated with
60         the key.
61
62         A policyPath is composed of two elements, separated by “/”.  A  poli‐
63         cyPath starts with “/policy”.  The second path element identifies the
64         policy or policy template using a meaningful name.
65
66-a, --authValue=STRING:
67
68         The new UTF-8 password.  Optional parameter.  If it is neglected then
69         the  user  is  queried interactively for a password.  To set no pass‐
70         word, this option should be used with the  empty  string  ("").   The
71         maximum  password size is determined by the digest size of the chosen
72         name hash algorithm in  the  cryptographic  profile  (cf.,  fapi-pro‐
73         file(5)).   For  example,  choosing  SHA256 as hash algorithm, allows
74         passwords of a maximum size of 32 characters.
75

COMMON OPTIONS

77       This collection of options are common to all tss2 programs and  provide
78       information that many users may expect.
79
80-h,  --help  [man|no-man]: Display the tools manpage.  By default, it
81         attempts to invoke the manpager for the  tool,  however,  on  failure
82         will  output  a short tool summary.  This is the same behavior if the
83         “man” option argument is specified, however if explicit “man” is  re‐
84         quested,  the  tool  will  provide errors from man on stderr.  If the
85         “no-man” option if specified, or the manpager fails,  the  short  op‐
86         tions will be output to stdout.
87
88         To  successfully use the manpages feature requires the manpages to be
89         installed or on MANPATH, See man(1) for more details.
90
91-v, --version: Display version information for this  tool,  supported
92         tctis and exit.
