function memoize(func) {
  var cache = {};

  return function memoized() {
    var key = arguments.length === 1 &&
              typeof arguments[0] === 'string' ?
                arguments[0] : JSON.stringify(arguments);
    var cached = cache[key];
    return  cached !== undefined? cached :
            cache[key] = func.apply(this, arguments);
  };
}

exports.normalizePubKey = memoize(normalizePubKey)
