How to use the binary.ByteString.wrap function in binary

value: function(algorithm) {
        var {ByteString} = require('binary');
        var md = java.security.MessageDigest.getInstance(algorithm || 'MD5');
        var b = ByteString.wrap(md.digest(this.toByteString()));
        var buf = [];

        for (var i = 0; i < b.length; i++) {
            var j = b[i];
            if (j < 16) {
                buf[buf.length] = '0';
            }
            buf[buf.length] = j.toString(16);
        }
        return buf.join('');
    }, writable: true
});

        finalUrl: String(response.getFinalUrl()),
        statusCode: response.getResponseCode(),
        headers: headers
    }
}
