A Signer object is created using an \s-1RSA\s0 private key. The object can be used to sign multiple \s-1RDF\s0 graphs. The signature should be independent of the \s-1RDF\s0 serialisation used, so that Turtle and \s-1RDF/XML\s0 files containing equivalent triples should generate the same signature.

RDF::Crypt::Signer can also be used to verify signatures using the private key of the signer.
