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-profile(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.
