opendkim-testmsg(8)                  System Manager's Manual                  opendkim-testmsg(8)



NAME
       opendkim-testmsg - DKIM message tst

SYNOPSIS
       opendkim-testmsg [-C] [-d domain] [-K] [-k keypath] [-s selector] [-t path]

DESCRIPTION
       opendkim-testmsg signs or verifies an input message.  This is similar to the test mode for
       opendkim(8) except that it does not use the same configuration system or milter interface.
       Rather, it is a direct access to the DKIM library with those functions "out of the way".

       The  message  is  read  from standard input.  In signing mode, the complete signed message
       will then be written to standard output.  When verifying, there will be no  output  unless
       an error occurred.

       To  sign a message, the -d, -k and -s settings in the SYNOPSIS above must be provided.  If
       all of them are absent, the input message will be verified.   If  some  but  not  all  are
       present, an error is returned.


OPTIONS
       -C     If  specified,  the  signature header field generated in signing mode will be line-
              terminated with carriage-return line-feed, instead of just line-feed.

       -d domain
              Names the domain in which signing is to be  done.   More  specifically,  names  the
              domain  in which the public key matching the provided private key would be found in
              a live test.

       -K     Arranges to keep temporary files  generated  during  message  canonicalization  for
              debugging purposes.

       -k keypath
              Specifies  the  path to the private key file which should be used to sign the input
              message.

       -s selector
              Names the selector within the specified domain that should be included in the  sig‐
              nature.

       -t path
              Specifies the directory in which temporary files are to be created.  The default is
              /tmp.
