opendkim-testmsg - DKIM message tst

       Copyright (c) 2011-2013, The Trusted Domain Project.  All rights reserved.

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.

-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.

       -ddomain
              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.

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

       -sselector
              Names the selector within the specified domain that should be included in the signature.

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