NAME

       RDF::Crypt::Signer - signs RDF graphs with RSA

SYNOPSIS

        use 5.010;
        use File::Slurp qw< slurp >;
        use RDF::Crypt::Signer;
        use RDF::TrineX::Functions qw< parse >;

        my $sign = RDF::Crypt::Signer->new_from_file(
           '/path/to/private-key.pem'
        );

        my $raw    = slurp '/path/to/important.ttl';
        my $graph  = parse '/path/to/important.ttl';

        my $detached_sig                   = $sign->sign_model($graph);
        my $turtle_with_embedded_signature = $sign->sign_embed_turtle($raw);

DESCRIPTION

       A Signer object is created using an RSA private key. The object can be used to sign
       multiple RDF graphs. The signature should be independent of the RDF serialisation used, so
       that Turtle and RDF/XML 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.
