10
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.
19
21 tss2_nvread(1) - This command reads the entire data from an NV index of
22 the TPM.
23
25 These are the availabe options:
26
27 • -f, --force:
28
29 Force overwriting the output file.
30
31 • -o, --data=FILENAME or - (for stdout):
32
33 Returns the value read from the NV space.
34
35 • -p, --nvPath=STRING:
36
37 Identifies the NV space to read.
38
39 • -l, --logData=FILENAME or - (for stdout):
40
41 Returns the JSON encoded log, if the NV index is of type "extend" and
42 an empty string otherwise. Optional parameter.
43
45 This collection of options are common to all tss2 programs and provide
46 information that many users may expect.
47
48 • -h, --help [man|no-man]: Display the tools manpage. By default, it
49 attempts to invoke the manpager for the tool, however, on failure
50 will output a short tool summary. This is the same behavior if the
51 "man" option argument is specified, however if explicit "man" is re‐
52 quested, the tool will provide errors from man on stderr. If the
53 "no-man" option if specified, or the manpager fails, the short op‐
54 tions will be output to stdout.
55
56 To successfully use the manpages feature requires the manpages to be
57 installed or on MANPATH, See man(1) for more details.
58
59 • -v, --version: Display version information for this tool, supported
60 tctis and exit.
