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 ac-
cess 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 verify-
ing, 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, in-
stead of just line-feed.
-d domain
Names the domain in which signing is to be done. More specifi-
cally, 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 canon-
icalization 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 cre-
ated. The default is /tmp.
