Windows Store application (Windows Runtime) has provided rich support on cryptography and PKI programming. We can use the built-in classes to perform common crypto operations like symmetric & asymmetric encryption, digital signing, hashing, etc… (see reference below):

 

#Crypto and PKI application capabilities (Windows)

https://msdn.microsoft.com/en-us/library/windows/apps/hh464922.aspx

 

And the Windows SDK sample collection has also provided a detailed sample to demonstrate various crypto programming cases supported in Windows Store application.

 

#CryptoWinRT sample

https://code.msdn.microsoft.com/windowsapps/CryptoWinRT-54ff3d9f

 

However, the document and sample haven’t provided more information about how we can connect the crypto code to the X509 certificate which is usually used in PKI based crypto programming scenario. In a recent thread, someone has asked the question about how to load the public key from a x509 certificate (with RSA sha1 algorithm) and perform asymmetric encryption/signing with the key (see thread below):

 

https://social.msdn.microsoft.com/Forums/en-US/winappswithhtml5/thread/17e1467a-2de7-47d2-8d8c-130518eaac68

 

At first, I think the solution should be quite straightforward and might be resolved by a simple built-in function. But after some research, I found that there is no built-in class/method (in the current Windows Store/Windows Runtime library) which can directly extract the public key (or key pairs) from a given X509 certificate (.cer or .pfx file). Therefore, in this blog entry, I’ll try summarizing two approaches we can use for performing asymmetric encryption by using the public key from an x509 certificate in Windows Store application.

 

Pre-extract the public key in x509 certificate and save it in file (or code) for windows store app

In this case, we need to write some standard .NET code to extract the public key data from X509 certificate and save it (for later using in windows store app). Here is the sample code (in a standard .NET Winform app) for extracting and displaying the public key (in base64 format):

 

private void btnFindCert_Click(object sender, EventArgs e)

{

    var store = new X509Store(StoreName.My, StoreLocation.LocalMachine);

    store.Open(OpenFlags.ReadOnly);

 

    var certs = store.Certificates.Find(X509FindType.FindBySubjectName, txtSubjectName.Text, false);

 

    if (certs.Count <= 0)

    {

        MessageBox.Show("No Certificate found!");

        return;

    }

 

    var cert = certs[0];

    var sb = new StringBuilder();

 

    sb.AppendFormat("\r\nSubject Name:{0}\r\nThumbprint:{1}\r\nIssuer:{2}\r\n", cert.SubjectName.Name, cert.Thumbprint, cert.Issuer);

         

    var pubKeyStr = Convert.ToBase64String(cert.GetPublicKey());

    sb.AppendFormat("\r\nPublic Key (can be used in WinRT):{0}\r\n", pubKeyStr);

 

 

    txtOutput.AppendText(sb.ToString());

 

    store.Close();

}

 

 

After getting the public key data (bytes), we can directly load it in Windows Store app through AsymmetricAlgorithmProvider.importPublicKey method. Here is the complete code for loading the public key (bytes) and use it for data encryption in Windows Store app (javascript):

 

document.getElementById("btnEncryptByRawKey").addEventListener("click", function () {

 

                // Get from the WinFormCertTool

                var pubKeyStr = "MIGJAoGBAN34SRLiTkVvaUXXhLir3eGmEzV8M8x1Qf+WX6U67ML6tyzWN3oaMya94C1/G5VaG4fut9LpR/047rjuCJFZ3fItgOZXJJqzP6cX4lqVLj954IBQAJMrzzZrGhmBLuPjx9DcISYG+v0DlAj9gstxPPGFwjG2yJK9ADG/hIsi84OZAgMBAAE=";

                var pubKeyBytes = cryptoNS.CryptographicBuffer.decodeFromBase64String(pubKeyStr);

 

                var alg = cryptoNS.Core.AsymmetricKeyAlgorithmProvider.openAlgorithm(cryptoNS.Core.AsymmetricAlgorithmNames.rsaPkcs1);

                var pubKey = alg.importPublicKey(pubKeyBytes, cryptoNS.Core.CryptographicPublicKeyBlobType.pkcs1RsaPublicKey);

 

                var dataToEncrypt = document.getElementById("txtDataToSecure").value;

                var dataBytes = cryptoNS.CryptographicBuffer.convertStringToBinary(dataToEncrypt, cryptoNS.BinaryStringEncoding.utf8);

                var encryptedBytes = cryptoNS.Core.CryptographicEngine.encrypt(pubKey, dataBytes, null);

                var encryptedData = cryptoNS.CryptographicBuffer.encodeToBase64String(encryptedBytes);

 

                txtOutput.value = "Encrypted data:" + encryptedData;

                console.log(txtOutput.value);

 

            });

 

Manually parse the X509 certificate content (.cer file) and extract the public key in Windows Store app

If we cannot pre-extract the public key information from certificate and have to load the key info in Windows Store app directly, then we have to manually parse the X509 certificate data (.cer file). Thanks for Carlos who has provided a helper class which can be used in Windows Store app (in a Windows Runtime library) for extracting public key from x509 certificate binary content:

                count++;

            } while (fFinished == false);

 

            return dwNums;

        }

 

 

    }

}

 

 

Then, we can use this class in our Windows Store app to extract public key (from a given x509 certificate file) and perform RSA encryption (see javascript code below):

 

document.getElementById("btnEncryptByCertFile").addEventListener("click", function () {

 

    // Use file picker to select a x509 certificate file (.cer file)

    var openPicker = new Windows.Storage.Pickers.FileOpenPicker();

    openPicker.viewMode = Windows.Storage.Pickers.PickerViewMode.list;

    openPicker.fileTypeFilter.replaceAll([".cer"]);

 

    openPicker.pickSingleFileAsync().then(function (file) {

        return Windows.Storage.FileIO.readBufferAsync(file);

    }).done(

        function (buffer) {

                            

            var isBase64Cert = document.getElementById("rdCertBASE64").checked;

 

            var certStr = "";

            if (isBase64Cert) {

 

                // Base 64 format cer, need to extract the binary part

                certStr = cryptoNS.CryptographicBuffer.convertBinaryToString(cryptoNS.BinaryStringEncoding.utf8, buffer);

                certStr = certStr.replace("-----BEGIN CERTIFICATE-----", "");

                certStr = certStr.replace("-----END CERTIFICATE-----", "");

                certStr = certStr.trim();

 

 

            } else {

                // For DER binary format .cer file

                certStr = cryptoNS.CryptographicBuffer.encodeToBase64String(buffer);

            }

 

            // Extract the public key from cert binary

            var pubKey = RSACertLib.RSAUtils.getCryptographicPublicKeyFromCert(certStr);

 

            

            var dataToEncrypt = "This is an apple!";

            var bytesToEncrypt = cryptoNS.CryptographicBuffer.convertStringToBinary(dataToEncrypt, cryptoNS.BinaryStringEncoding.utf8);

 

            var encryptedBytes = cryptoNS.Core.CryptographicEngine.encrypt(pubKey, bytesToEncrypt, null);

            var encryptedData = cryptoNS.CryptographicBuffer.encodeToBase64String(encryptedBytes);

 

            txtOutput.value = "encryptedData:" + encryptedData;

            console.log("encryptedData:" + encryptedData);

        },

        function (err) {

            txtOutput.value = err;

            console.log(err);

        }

    );

 

});

针对这样的情况，我们计划专门为团购爱好者打造一个简单，快速，统一的团购信息浏览和查找途径；并且主要考虑了针对用户在一些新型智能移动设备上的使用体验。随着微软公司新发布的Windows 8 操作系统逐渐在PC和移动平板中广泛应用，我们将首先推出基于Windows 商店应用的“团购信息汇“应用程序。该程序将方便用户在Windows 8系统的PC或者移动设备中从各大主流团购站点中获取和查找最新的团购信息。

当前版本的团购信息汇应用程序将支持大众点评网，美团网，拉手网，F团，糯米网，嘀嗒团，爽团网和满座网这八大知名的团购网站。

 

 

 

同时Windows 8 应用商店程序的横竖屏多样化的视角使得用户可以很方便地在各种模式下切换团购站点。

 

更为重要的的是，团购信息汇程序将会覆盖20多个国内的大城市（包括北京，上海，广州，杭州，南京，郑州等）以满足尽可能多的团购爱好者。用户可以很方便地在应用程序中随时切换想要关注的城市。

 

 

每当用户选择了具体的团购站点以及关注的城市后，便可以在相应的团购列表中浏览所有相关的团购信息。所有团购信息都将根据时间定期刷新，用户也可以随时根据需要手工刷新信息。

 

 

与团购站点导航界面类似，用户在Windows 8 设备上可以根据需要在各种不同的视角模式中浏览团购信息。如在手持平板中纵向地浏览。

 

 

或者是通过Windows 8 应用程序独有的侧边贴靠模式在系统浏览器中同步查看团购网站上的原始信息。

 

 

为了便于用户快速的查找自己感兴趣的团购信息，应用程序在所有模式下都提供了搜索功能。这样用户可以通过关键字来快速地定位到包含特定内容的团购信息。

 

 

如今的互联网已经是Social的世界，用户可以方便的在各种不同的网站或者应用程序间（通过电脑或者是各种移动设备）分享和交流各种信息和话题。作为一款坚固移动设备的应用，团购信息汇同样集成了信息分享功能。用户可以随时将自己发现的团购信息通过设备上的其他互联网应用分享给朋友.

 

 

比如我们可以很方便地把某条特定的团购信息通过新浪微博分享给朋友。

 

 

对于Windows 8 的用户来说，动态此贴一定不会陌生。通过动态磁铁我们可以第一时间在屏幕上获得Windows 商店应用的最新动态信息。团购信息汇同样提供了动态磁铁提示功能，用户可以在还没打开应用程序时就了解到一些最新的团购信息；文字+图片结合的动态磁铁无疑也使得我们的系统桌面更加的丰富多彩。

 

 

总的来说，团购信息汇将致力于成为团购爱好者浏览和查找团购信息的好帮手。同时，对于当前的初始版本，其中一定会存在着诸多的缺陷和不足；因此我们非常欢迎大家随时向我们提供宝贵意见和建议；也希望团购信息汇能够在广大团购爱好者和用户的帮助和鼓励中不断成长。

If you are developers of IT Professionals who often access Microsoft online forums like MSDN, TechNet and Office 365, you can now make the access on your palms through your smart mobile phones.





Surely, this Mobile service is still far from full-fleged and powerful as it supports readonly to the forums content. However, we will try out best to keep moving and make it better and better. Meanwhile, if you have any good ideas for improving this, please feel free to tell us.
