tss2_gettpm2object(1) General Commands Manual tss2_gettpm2object(1) NAME tss2_gettpm2object(1) SYNOPSIS tss2_gettpm2object [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 parame- ters for all keys and operations of a specific TPM interaction like the name hash algorithm, the asymmetric signature algorithm, scheme and pa- rameters and PCR bank selection. DESCRIPTION tss2_gettpm2object(1) - With this command for FAPI objects context files which can be used by tpm2 tool commands can be created. For per- sistent object only the textual representation of the handle number as hex number will be written and for keys a tpm2 tool context file will be written. If the default TCTI differs from the FAPI profile the de- fault the tcti can be defined with the -T (-tcti) option. Note To avoid wrong nv_written state in keystore before writing data to the NV ram with tpm2_nvwrite, at least an empty string should be written with tss2_nvwrite. OPTIONS These are the available options: • -f, --force: Force overwriting the output file. • -p, --path=STRING: Path of the object for which the application data will be loaded. • -c, --context=FILENAME or - (for stdout): The returned key context or handle. 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 re- quested, the tool will provide errors from man on stderr. If the "no-man" option if specified, or the manpager fails, the short op- tions 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 tss2_gettpm2object --path=/HS/SRK/myRSACrypt --key-context=mykey.ctx tss2_gettpm2object --path=/nv/Owner/mynv -c- The command can be used in options of tpm2 commands: handle=$(tss2_gettpm2object --path=/nv/Owner/mynv -c-) tpm2_nvread $handle RETURNS 0 on success or 1 on failure.
