NAME

       tss2_delete(1) -

SYNOPSIS

       tss2_delete [OPTIONS]

SEE ALSO

       fapi-config(5)  to  adjust Fapi parameters like the used cryptographic profile and TCTI or
       directories for the Fapi metadata storages.

       fapi-profile(5) to determine the cryptographic algorithms and parameters for all keys  and
       operations  of  a  specific  TPM  interaction like the name hash algorithm, the asymmetric
       signature algorithm, scheme and parameters and PCR bank selection.

DESCRIPTION

       tss2_delete(1) - This command deletes the given key, policy or NV from the  FAPI  metadata
       store and the TPM.  Depending on the entity type, one of the following actions are taken:

              - Non-persistent key: Flush from TPM (if loaded) and delete public and private blobs from keystore.
              - Persistent keys: Evict from TPM and delete public and private blobs from keystore
              - Primary keys: Flush from TPM and delete public blob from keystore
              - NV index: Undefine NV index from TPM and delete public blob from FAPI metadata store
              - Policies: Delete entry from policy store
              - Hierarchy, PCR: These are not deletable
              - Special keys ek, srk: These are not deletable

OPTIONS

       These are the available options:

       • -p, --path=STRING:

         The path to the entity to delete.

COMMON OPTIONS

       This  collection  of  options are common to all tss2 programs and provide information that
       many users may expect.

       • -h, --help [man|no-man]: Display the tools manpage.  By default, it attempts  to  invoke
         the  manpager  for the tool, however, on failure will output a short tool summary.  This
         is the same behavior if the “man” option argument  is  specified,  however  if  explicit
         “man”  is  requested,  the tool will provide errors from man on stderr.  If the “no-man”
         option if specified, or the manpager fails, the short options will be output to stdout.

         To successfully use the manpages feature requires the manpages to  be  installed  or  on
         MANPATH, See man(1) for more details.

       • -v, --version: Display version information for this tool, supported tctis and exit.

EXAMPLE

Deletes storage hierarchy (HS) and everything below it:

              tss2_delete --path=/HS

RETURNS

       0 on success or 1 on failure.
