tss2_sign(1) General Commands Manual tss2_sign(1) NAME tss2_sign(1) - SYNOPSIS tss2_sign [OPTIONS] SEE ALSO fapi-config(5) to adjust Fapi parameters like the used cryptographic pro- file 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_sign(1) - This command uses a key inside the TPM to sign a digest value using the TPM signing schemes as specified in the cryptographic pro- file (cf., fapi-profile(5)). OPTIONS These are the available options: * -p, --keyPath=STRING: The path to the signing key. * -s, --padding=STRING: The padding scheme used. Possible values are "RSA_SSA", "RSA_PSS" (case insensitive). Optional parameter. If omitted, the default padding spec- ified in the cryptographic profile (cf., fapi-profile(5)) is used. * -c, --certificate=FILENAME or - (for stdout): The certificate associated with keyPath in PEM format. Optional parame- ter. * -d, --digest=FILENAME or - (for stdin): The data to be signed, already hashed. * -f, --force: Force overwriting the output file. * -k, --publicKey=FILENAME or - (for stdout): The public key associated with keyPath in PEM format. Optional parame- ter. * -o, --signature=FILENAME or - (for stdout): Returns the signature in binary form. COMMON OPTIONS This collection of options are common to all tss2 programs and provide in- formation that many users may expect. * -h, --help [man|no-man]: Display the tools manpage. By default, it at- tempts to invoke the manpager for the tool, however, on failure will out- put 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 speci- fied, or the manpager fails, the short options will be output to stdout. To successfully use the manpages feature requires the manpages to be in- stalled or on MANPATH, See man(1) for more details. * -v, --version: Display version information for this tool, supported tctis and exit. EXAMPLE tss2_sign --keyPath=HS/SRK/myRSASign --padding="RSA_PSS" --digest=digest.file --signature=signature.file --publicKey=publicKey.file RETURNS 0 on success or 1 on failure.
