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 DKIMSignature
       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.
