SYNOPSIS

9       tss2_createnv [OPTIONS]
10

DESCRIPTION

12       tss2_createnv(1) - This command creates an NV index in the TPM.
13

OPTIONS

15       These are the available options:
16
17       · -p, --path STRING:
18
19         Path of the new NV space.
20
21         The  path is composed of three elements, separated by “/”.  An nvPath
22         starts with “/nv”.  The second path element identifies the NV  handle
23         range  for the nv object.  This includes the following values: Owner,
24         TPM, Platform, Endorsement_Certificate, Platform_Certificate,  Compo‐
25         nent_OEM, TPM_OEM, Platform_OEM, PC-Client, Server, Virtualized_Plat‐
26         form, MPWG, Embedded.  The third path element identifies  the  actual
27         NV-Index using a meaningful name.
28
29       · -t, --type STRING:
30
31         Identifies the intended usage.  Optional parameter.  Types may be any
32         comma-separated combination of:
33
34                - "noda": Sets the noda attribute of a key or NV index.
35                - "bitfield": Sets the NV type to bitfield.
36                - "counter": Sets the NV type to counter.
37                - "pcr": Sets the NV type to pcr-like behavior.
38                - Hint: If none of the previous three keywords is provided a regular NV
39                  index is created.
40
41       · -s, --size INTEGER:
42
43         The size in bytes of the NV index to be created.  Can be  omitted  if
44         size  can be inferred from the type; e.g. an NV index of type counter
45         has a size of 8 bytes.
46
47       · -P, --policyPath STRING:
48
49         Identifies the policy to be associated with the new  NV  space.   Op‐
50         tional  parameter.  If omitted then no policy will be associated with
51         the key.
52
53         A policyPath is composed of two elements, separated by “/”.  A  poli‐
54         cyPath starts with “/policy”.  The second path element identifies the
55         policy or policy template using a meaningful name.
56
57       · -a, --authValue STRING:
58
59         The new UTF-8 password.  Optional parameter.  If it is neglected then
60         the  user  is  queried interactively for a password.  To set no pass‐
61         word, this option should be used with the empty string ("").
62

COMMON OPTIONS

64       This collection of options are common to all tss2 programs and  provide
65       information that many users may expect.
66
67       · -h,  --help  [man|no-man]: Display the tools manpage.  By default, it
68         attempts to invoke the manpager for the  tool,  however,  on  failure
69         will  output  a short tool summary.  This is the same behavior if the
70         “man” option argument is specified, however if explicit “man” is  re‐
71         quested,  the  tool  will  provide errors from man on stderr.  If the
72         “no-man” option if specified, or the manpager fails,  the  short  op‐
73         tions will be output to stdout.
74
75         To  successfully use the manpages feature requires the manpages to be
76         installed or on MANPATH, See man(1) for more details.
77
78       · -v, --version: Display version information for this  tool,  supported
79         tctis and exit.
