Mail::DKIM::PrivateKey(3) User Contributed Perl Documentation Mail::DKIM::PrivateKey(3)

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.
