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 signature.

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