NAME

Mail::DKIM::PrivateKey − a private key loaded in memory for DKIM signing

VERSION

version 1.20230911

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.
