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

VERSION
       version 1.20200907

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.
