Mail::DKIM::PublicKey(3)				User Contributed Perl Documentation				  Mail::DKIM::PublicKey(3)

CONSTRUCTOR
   fetch() - retrieve a public key record from DNS
	 my $public_key = Mail::DKIM::PublicKey->fetch(
			     Protocol => "dns",
			     Selector => "brisbane",
			     Domain => "example.com",
			   );

       If the public key is found, a Mail::DKIM::PublicKey object is returned, representing the information found in DNS.  If the public key does
       not exist in DNS, then "undef" is returned.  If a DNS error occurs while fetching the key, then this method will "die".	If the public key
       was found, but is not valid (e.g. it is "revoked"), then this method will "die".

METHODS
   granularity() - get or set the granularity (g=) field
	 my $g = $public_key->granularity;

	 $public_key->granularity("*");

       Granularity of the key. The value must match the Local-part of the effective "i=" tag of the DKIM-Signature header field.  The granularity
       is a literal value, or a pattern with a single '*' wildcard character that matches zero or more characters.

       If no granularity is defined, then the default value, '*', will be returned.
