NAME

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

CONTENTS

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.
