NAME

       tss2_verifysignature(1) -

SYNOPSIS

       tss2_verifysignature [OPTIONS]

DESCRIPTION

       tss2_verifysignature(1)  -  This  command verifies a signature using a public key found in the passed key
       path.  The used signature verification scheme is specified in the cryptographic profile  (cf.,  fapi-pro‐
       file(5)).

OPTIONS

       These are the available options:

       • -d, --digest=FILENAME or - (for stdin):

         The data that was signed, already hashed according to the cryptographic profile (cf., fapi-profile(5)).

       • -p, --keyPath=STRING:

         Path to the verification public key.

       • -i, --signature=FILENAME or - (for stdin):

         The signature to be verified.

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

              tss2_verifysignature --keyPath=ext/myRSASign --digest=digest.file --signature=signature.file

RETURNS

       0 on success or 1 on failure.
