Mail::DKIM::PublicKey.3pm

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.
