10

SEE ALSO

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_gettpmblobs(1) - This command returns the public and private blobs
22       of an object, such that they could be loaded by a low-level  API  (e.g.
23       ESAPI).  It also returns the policy associated with these blobs in JSON
24       format.
25

OPTIONS

27       These are the available options:
28
29       • -f, --force:
30
31         Force overwriting the output file.
32
33       • -p, --path=STRING:
34
35         The path of the object for which the blobs will be returned.
36
37       • -u, --tpm2bPublic=FILENAME or - (for stdout):
38
39         The returned public area of the object as a marshalled  TPM2B_PUBLIC.
40         Optional parameter.
41
42       • -r, --tpm2bPrivate=FILENAME or - (for stdout):
43
44         The  returned  private  area of the object as a marshalled TPM2B_PRI‐
45         VATE.  Optional parameter.
46
47       • -l, --policy=FILENAME or - (for stdout):
48
49         The returned policy associated with the object, encoded in JSON.  Op‐
50         tional parameter.
51

COMMON OPTIONS

53       This  collection of options are common to all tss2 programs and provide
54       information that many users may expect.
55
56       • -h, --help [man|no-man]: Display the tools manpage.  By  default,  it
57         attempts  to  invoke  the  manpager for the tool, however, on failure
58         will output a short tool summary.  This is the same behavior  if  the
59         "man"  option argument is specified, however if explicit "man" is re‐
60         quested, the tool will provide errors from man  on  stderr.   If  the
61         "no-man"  option  if  specified, or the manpager fails, the short op‐
62         tions will be output to stdout.
63
64         To successfully use the manpages feature requires the manpages to  be
65         installed or on MANPATH, See man(1) for more details.
66
67       • -v,  --version:  Display version information for this tool, supported
68         tctis and exit.
