16       ters for all keys and operations of a specific TPM interaction like the

DESCRIPTION

21       tss2_delete(1)  - This command deletes the given key, policy or NV from
22       the FAPI metadata store and the TPM.  Depending on the entity type, one
23       of the following actions are taken:
24
25              - Non-persistent key: Flush from TPM (if loaded) and delete public and private blobs from keystore.
26              - Persistent keys: Evict from TPM and delete public and private blobs from keystore
27              - Primary keys: Flush from TPM and delete public blob from keystore
28              - NV index: Undefine NV index from TPM and delete public blob from FAPI metadata store
29              - Policies: Delete entry from policy store
30              - Hierarchy, PCR: These are not deletable
31              - Special keys ek, srk: These are not deletable

OPTIONS

34       These are the available options:
35
36       • -p, --path=STRING:
37
38         The path to the entity to delete.

COMMON OPTIONS

41       This  collection of options are common to all tss2 programs and provide
42       information that many users may expect.
43
44       • -h, --help [man|no-man]: Display the tools manpage.  By  default,  it
45         attempts  to  invoke  the  manpager for the tool, however, on failure
46         will output a short tool summary.  This is the same behavior  if  the
47         “man”  option argument is specified, however if explicit “man” is re‐
48         quested, the tool will provide errors from man  on  stderr.   If  the
49         “no-man”  option  if  specified, or the manpager fails, the short op‐
50         tions will be output to stdout.
51
52         To successfully use the manpages feature requires the manpages to  be
53         installed or on MANPATH, See man(1) for more details.
54
55       • -v,  --version:  Display version information for this tool, supported
56         tctis and exit.
