Why hash() just return string rather than object?

[moslemezzati]

First of all many thanks for your lib, I have a problem to work with your module. when I use hash() it returns a string that has a object for example

pw.hash(body.password, function (err, hash) {
      if (err) {
        console.error(err);
        return;
      }
console.log(type of hash) // string
}

but I need hash.hash

It returns a string for database storage and retrieval. The verify function validates using the string. If you need to access the object, you can do so by converting the string to an object with JSON.parse(string).
