Resource description framework (rdf) is a standard model for data interchange on the web.

rdf-crypt provides a variety of objects and methods for cryptographically manipulating (encrypting, decrypting, signing and verifying) rdf graphs using rsa and webid.

rdf-crypt uses a role-based architecture. classes like rdf::crypt::encrypter are in fact very slim wrappers around collections of roles. most of the interesting behaviour is documented in the role modules.
