NAMEMail::OpenDKIM - Provides an interface to libOpenDKIMSYNOPSIS# sign outgoing message use Mail::DKIM::Signer; # create a signer object my $dkim = Mail::OpenDKIM::Signer->new( Algorithm => 'rsa-sha1', Method => 'relaxed', Domain => 'example.org', Selector => 'selector1', KeyFile => 'private.key', ); # read an email and pass it into the signer, one line at a time while(<STDIN>) { # remove local line terminators chomp; s/\015$//; # use SMTP line terminators $dkim->PRINT("$_\015\012"); } $dkim->CLOSE(); # what is the signature result? my $signature = $dkim->signature; print $signature->as_string; # check validity of incoming message my $o = Mail::OpenDKIM->new(); $o->dkim_init(); my $d = $o->dkim_verify({ id => 'MLM', }); $msg =~ s/\n/\r\n/g; $d->dkim_chunk({ chunkp => $msg, len => length($msg) }); $d->dkim_chunk({ chunkp => '', len => 0 }); $d->dkim_eom(); my $sig = $d->dkim_getsignature(); $d->dkim_sig_process({ sig => $sig }); printf "0x\n", $d->dkim_sig_getflags({ sig => $sig }); $d->dkim_free(); $o->dkim_close(); DESCRIPTIONMail::OpenDKIM, coupled with Mail::OpenDKIM::DKIM, provides a means of calling libOpenDKIM from Perl. Mail::OpenDKIM implements those routine taking a DKIM_LIB argument; those taking a DKIM argument have been implemented in Mail::OpenDKIM::DKIM.Mail::OpenDKIM::Signer provides a drop in replacement for the signature process provided by Mail::DKIM::Signer. When an error is encountered, an Error::Simple object is thrown. SUBROUTINES/METHODSnewCreate a new signing/verifying object. After doing this you will need to call the dkim_init method before you can do much else.dkim_initFor further information, refer to http://www.opendkim.org/libopendkim/dkim_closeFor further information, refer to http://www.opendkim.org/libopendkim/dkim_flush_cacheFor further information, refer to http://www.opendkim.org/libopendkim/dkim_libfeatureFor further information, refer to http://www.opendkim.org/libopendkim/dkim_signFor further information, refer to http://www.opendkim.org/libopendkim/Returns a Mail::OpenDKIM::DKIM object. dkim_verifyFor further information, refer to http://www.opendkim.org/libopendkim/Returns a Mail::OpenDKIM::DKIM object. The memclosure argument is ignored. dkim_getcachestatsFor further information, refer to http://www.opendkim.org/libopendkim/dkim_set_dns_callbackFor further information, refer to http://www.opendkim.org/libopendkim/dkim_set_key_lookupFor further information, refer to http://www.opendkim.org/libopendkim/dkim_set_signature_handleFor further information, refer to http://www.opendkim.org/libopendkim/dkim_set_signature_handle_freeFor further information, refer to http://www.opendkim.org/libopendkim/dkim_set_signature_tagvaluesFor further information, refer to http://www.opendkim.org/libopendkim/dkim_dns_set_query_cancelFor further information, refer to http://www.opendkim.org/libopendkim/dkim_dns_set_query_serviceFor further information, refer to http://www.opendkim.org/libopendkim/dkim_dns_set_query_startFor further information, refer to http://www.opendkim.org/libopendkim/dkim_dns_set_query_waitreplyFor further information, refer to http://www.opendkim.org/libopendkim/dkim_optionsFor further information, refer to http://www.opendkim.org/libopendkim/dkim_libversionStatic method.dkim_ssl_versionStatic method.dkim_getcachestatsStatic method.dkim_getresultstrCalls C routine of same name.dkim_sig_geterrorstrCalls C routine of same name.dkim_mail_parseCalls C routine of same name.EXPORTMany DKIM_* constants, e.g. DKIM_STAT_OK are exported.SEE ALSOMail::DKIMhttp://www.opendkim.org/libopendkim/ RFC 4870, RFC 4871 REPOSITORY<https://github.com/infracaninophile/Mail-OpenDKIM.git>DEPENDENCIESThis module requires these other modules and libraries:Test::More libOpenDKIM 2.10 (http://www.opendkim.org/libopendkim/) C compiler NOTESTested against libOpenDKIM 2.10.3.Only portions of Mail::DKIM::Signer interface, and the support for it, have been implemented. Please report any bugs or feature requests to "bug-mail-opendkim at rt.cpan.org", or through the web interface at <http://rt.cpan.org/NoAuth/ReportBug.html?Queue=Mail-OpenDKIM>. I will be notified, and then you'll automatically be notified of progress on your bug as I make changes. The signature creation rountines have been tested more thoroughly than the signature verification routines. Feedback will be greatfully received.
