SYNOPSIS

    #You’ll probably instantiate this class using Parser.pm
    #or PrivateKey’s get_public_key() method.

    #cf. JSON Web Algorithms (RFC 7518, page 5)
    #These return 1 or 0 to indicate verification or non-verification.
    $pbkey->verify_RS256($message, $sig);
    $pbkey->verify_RS384($message, $sig);
    $pbkey->verify_RS512($message, $sig);

    my $enc = $pbkey->encrypt_raw($payload);

    #----------------------------------------------------------------------

    my $der = $pbkey->to_der();
    my $pem = $pbkey->to_pem();

    #For use in creating PKCS #10 CSRs and X.509 certificates
    my $pub_der = $pbkey->to_subject_der();

    #----------------------------------------------------------------------

    $pbkey->size();                 #modulus length, in bits
    $pbkey->modulus_byte_length();

    #----------------------------------------------------------------------
    # The following all return instances of Crypt::Perl::BigInt,
    # a subclass of Math::BigInt.
    # The pairs (e.g., modulus() and N()) are aliases.
