NAME

       RDF::Crypt::Role::DoesEncrypt - scrambling methods

DESCRIPTION

   Object Methods
       "encrypt_model($model)"
           Returns an encrypted serialisation of the data.

           The encryption works by serialising the data as RDF/XML, then encrypting it with
           "encrypt_text".

       "send_model_by_email($model, \%opts)"
           This method only works on objects that were constructed using "new_from_webid".
           Encrypts the model for the holder of the WebID, and sends it to an address specified
           in the WebID profile using foaf:mbox.

           Options:

           •   sendmail - hashref of options for Mail::Transport::Sendmail. The mere presence of
               this hashref will trigger Mail::Transport::Sendmail to be used as the delivery
               method.

           •   smtp - hashref of options for Mail::Transport::SMTP. The mere presence of this
               hashref will trigger Mail::Transport::SMTP to be used as the delivery method.

           •   from - email address for the message to come from.

           •   subject - message subject.

           •   filename - filename for encrypted attachment.

           •   headers - hashref of additional mail headers.

           Returns a the message's Message-ID, or undef if unsuccessful.

       "encrypt_text($str)"
           Encrypts a literal string which may or may not have anything to do with RDF.

           The return value is a base64-encoded string. The base64-decoded value consists of: (1)
           an initialisation vector, sixteen bytes shorter than the size of the key; (2) a 16-bit
           big-endian signed integer indicating the length of padding which was added to the
           payload of the message during encryption; (3) the payload, encrypted using cipher-
           block chaining with OAEP, with block length sixteen bytes shorter than the key size.
           These three parts are concatenated together in that order.

   Required Methods
       This role does not implement these methods, but requires classes to implement them
       instead:

       "encrypt_bytes($str)"
           Scrambles an octet string.
