=head1 NAME
RDF::Crypt::Verifier - verifies signed RDF graphs
=head1 SYNOPSIS
use 5.010;
use File::Slurp qw< slurp >;
use RDF::Crypt::Verifier;
use RDF::TrineX::Functions qw< parse >;
my $verify = RDF::Crypt::Verifier->new_from_file(
'/path/to/public-key.pem'
);
my $graph = parse '/path/to/important.ttl';
my $signature = slurp '/path/to/important.ttl.sig';
say "graph is trusted"
if $v->verify_model($graph, $signature);
=head1 DESCRIPTION
A Verifier object is created using an RSA public key. The object can be used
to verify signatures for multiple RDF graphs.
