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:

"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.
