由于有人决定downvote我，我做了一些更多的研究。有没有办法，你会从这些散列获得的电子邮件地址。你需要找到另一种方法来检索您的联系人和有emailadresses。到目前为止，我没有发现任何sollution做到这一点。

我发现一些非免费服务，会给你你所需要的。比其他，似乎只有大公司能得到的所有联系人的emailaddresses。我想从微软的安全利益和销售该选项是很大一笔钱。

下面是一个服务，你可以使用：

有一个愉快的一天。

I am new to stackeoverflow. I am trying to retrieve email address of contacts from Hotmail in asp.net.But its giving email hashes.

How can i get the email address of the contacts?below is the response i get from the API.

{
   "id": "contact.ca49847541d000000000000000000000000", 
   "first_name": abc, 
   "last_name": xyz, 
   "name": "test@test.net", 
   "gender": null, 
   "is_friend": true, 
   "is_favorite": false, 
   "user_id": "XXXXXXX4d520c", 
   "email_hashes": [
      "abbfa2d656170aa1b4bd596047b98f0a2cc7b106ccfd83434e6caff01c2bdd77"
   ], 
   "updated_time": "2011-11-12T08:15:26+0000"
}

Some more information:

A hash is not designed to be "decoded", The point is for you to be able to check it against an email address or addresses you already have.

Because someone decided to downvote me, I did some more research. There's no way you'll get the email addresses from these hashes. You need to find another way to retrieve your contacts and there emailadresses. So far, I did not find any sollution to do this.

I've found some non-free services that will give you what you need. Other than those, it seems only big companies are able to get the emailaddresses of all the contacts. I guess Microsoft benefits from security and sells this option for big money.

Here's one service you can use:

UPDATE: OpenContacts.NET is open-source library for importing contacts from popular web-mail services. Now supports: GMail, Yahoo! Mail, Live (Hotmail).

Have a nice day.
