Usage

Overview

- 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.

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.

Examples

Deletes storage hierarchy (HS) and everything below it:

tss2_delete --path=/HS

Returns

0 on success or 1 on failure.
