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

NAME

       opendkim-testkey - DKIM filter installation test

SYNOPSIS

       opendkim-testkey [-d domain] [-s selector] [-k keypath] [-v] [-x configfile]

DESCRIPTION

       opendkim-testkey verifies the setup of signing and verifying (private and public) keys for use with opendkim(8).

       The  test  program  will read a domain name and selector from the command line, configuration file or a key table, then query and parse the
       resulting DKIM key(s), reporting any errors found.

       If a key path is also provided, the test program will read the private key named and attempt to confirm that the private key  specified	by
       keypath (or in the key table) and the public DKIM key retrieved match.

OPTIONS

       -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 will be found.  This parameter must be provided either explicitly, or in the configuration file, or via a KeyTable  (see
	      opendkim.conf(5) for details).

       -k keypath
	      Specifies the path to the private key file which should be used for this test.  This parameter is optional

       -s selector
	      Names  the  selector within the specified domain whose public key should be retrieved and tested, comparing it to the private key if
	      provided.  This parameter must be provided either explicitly, or in the configuration file, or via a KeyTable (see  opendkim.conf(5)
	      for details).

       -v     Increases the amount of output (verbosity) of the program.  May be specified multiple times for increased output.

       -x conffile
	      Names a configuration file to be parsed.	See the opendkim.conf(5) man page for details.	The only values used are Domain, Selector,
	      KeyFile, KeyTable, TrustAnchorFile and UnboundConfigFile.  The default is /etc/opendkim.conf.

NOTES

       The test program will also complain if a private key file is readable by anyone other than the user executing the program.

VERSION

       This man page covers the version of opendkim-testkey that shipped with version 2.6.8 of OpenDKIM.

NAME

       Mail::DKIM::PrivateKey - a private key loaded in memory for DKIM signing

SYNOPSIS

	my $key1 = Mail::DKIM::PrivateKey->load(
		      File => "/path/to/private.key");

	my $key2 = Mail::DKIM::PrivateKey->load(
		      Data => $base64);

	# use the loaded key in a DKIM signing object
	my $dkim = Mail::DKIM::Signer->new(
		      Key => $key2,
		    );

CONSTRUCTOR

   load() - loads a private key into memory
	my $key1 = Mail::DKIM::PrivateKey->load(
		      File => "/path/to/private.key");

       Loads the Base64-encoded key from the specified file.

	 my $key2 = Mail::DKIM::PrivateKey->load(Data => $base64);

       Loads the Base64-encoded key from a string already in memory.

	 my $key3 = Mail::DKIM::PrivateKey->load(Cork => $openssl_object);

       Creates a Mail::DKIM::PrivateKey wrapper object for the given OpenSSL key object. The key object should be of type Crypt::OpenSSL::RSA.

METHODS

   cork() - access the underlying OpenSSL key object
	 $openssl_object = $key->cork;

       The returned object is of type Crypt::OpenSSL::RSA.

   sign_digest()
       Cryptographically sign the given message digest.

	 $key->sign_digest("SHA-1", sha1("my message text"));

       The first parameter is the name of the digest: one of "SHA-1", "SHA-256".

       The second parameter is the message digest as a binary string.

       The result should be the signed digest as a binary string.
