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.
