Mail::DKIM::PrivateKey.3pm

NAME

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.
