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.

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.
