Network Programming in .NET

I was following the excellent tutorial by Marin Todorov at http://www.raywenderlich.com/20734/beginning-passbook-part-1 , to create passbook (.pkpass) files from the command line – in order to understand what was going on, rather than depending on third party services to generate them.

However, the tutorial requires a mac, so I adapted it to work from windows as follows;

Download GNUWIN32 http://sourceforge.net/projects/gnuwin32/

—–Generate CSR———-

openssl genrsa -out passbookprivatekey.key 2048

Had to use template openssl.conf (https://www.tbs-certificats.com/openssl-dem-server-cert-thvs.cnf)

set OPENSSL_CONF=%cd%\openssl.cnf

openssl req -new -key passbookprivatekey.key -out PassbookCSR.certSigningRequest -subj “/emailAddress=you@domain.com, CN=Company, C=GB”

> send to apple, and get pass.cer back.

—–Convert CER to P12—–

openssl x509 -inform der -in pass.cer -out pass.pem

openssl pkcs12 -export -out pass.p12 -inkey passbookprivatekey.key -in pass.pem

password XXXX
—- And finally, create signature —-

openssl pkcs12 -in pass.p12 -clcerts -nokeys -out passcertificate.pem -passin pass:XXXX

openssl pkcs12 -in pass.p12 -nocerts -out passkey.pem -passin pass:XXXX -passout pass:XXXX

Download Apple AppleWWDRCA.cer

openssl x509 -inform der -in AppleWWDRCA.cer -out AppleWWDRCA.pem

openssl x509 -inform der -in pass.cer -out pass.pem

openssl smime -binary -sign -certfile AppleWWDRCA.pem -signer passcertificate.pem -inkey passkey.pem
-in manifest.json -out signature -outform DER -passin pass:XXXX

In the new iOS 9 Apple has decided that HTTP is too insecure for communications outside of your app… If you try to make one, you get this error:

Failed to load resource: The resource could not be loaded because the App Transport Security policy requires the use of a secure connection.

So, you can go and get a HTTPS security cert for your server – perhaps the best option – or you can add this to your info.plist

<key>NSAppTransportSecurity</key>
<dict>
<key>NSAllowsArbitraryLoads</key>
<true/>
</dict>

I discovered this when using http://www.remotelogcat.com on a Phonegap / Cordova iOS app.

SPF or “Sender Policy Framework” is a technique that aims to prevent email sender spoofing, and ultimately cut spam, it means that senders without a properly configured SPF record may be considered spam.

But if your business sends out email, and you want to make sure it isn’t marked as spam at your destination, then you might need to look at your SPF records.

The first step is to look at the headers of a received email, by a client that handles SPF, i.e. Gmail, and if you see something like spf=softfail ( domain of transitioning does not designate as permitted sender) , this means SPF is not configured correctly.

So, lets say, you know the sender is going to have IP address 1.2.3.4 – i.e. your outbound SMTP server. and your sender email is whatever@me.com – you need to then add a DNS TXT record to the domain me.com with the text

v=spf1 ip4:1.2.3.4 ~all

For the host “@” (non-www)

Then try sending the email again, and view the headers on the message, and it should say

Received-SPF: pass (google.com: domain of whatever@me.com designates 1.2.3.4 as permitted sender) client-ip=1.2.3.4;

This will come into play big time if you use Direct to MX software, or Amazon SES

Open developer tools, click console, type a non-existent variable – then click on

Uncaught ReferenceError: sdgdsg is not defined
at <anonymous>:2:1
at Object.InjectedScript._evaluateOn (<anonymous>:905:140)
at Object.InjectedScript._evaluateAndWrap (<anonymous>:838:34)
at Object.InjectedScript.evaluate (<anonymous>:694:21)

then the @ VM links

and you get;

Just this morning, we finally had our app “Under the crypt” accepted by Apple. It’s available for $0.99 cents and is available for Mountain Lion (64 Bit) or higher. It was designed with Xamarin – a .NET based cross platform app development system, – it is a port of a Phonegap app, that was previously available for Blackberry and Android on the Amazon app store. Thanks goes to to @veubeke, @UlrikeErdmann, and Tyber Zann for programming support!

If a HTTP call fails with a HTTP 500 error, and throws a WebException, you know something’s gone wrong, but sometimes the response from the server can explain more about what screwed up. I found myself writing this code over and over again, so here’s a single method that handles it;

private static string GetExceptionDetails(WebException exception)
{
string strResult = “”;
if (exception.Response != null)
{
var responseStream = exception.Response.GetResponseStream();
if (responseStream != null)
{
using (var reader = new StreamReader(responseStream))
{
strResult = reader.ReadToEnd();
}
}
}
return strResult;
}

Hope this helps solve your web related problems!

Printing an image using Xamarin turned out to be much easier than I thought, I loaded the image from a URL into an NSImageCell using;

                string strUrl = “http;// Some Url with an image“; // ?
                NSUrl url = new NSUrl (strUrl);
                this.imgCell.Image = new NSImage (url);

Then to print it, I used the command;

    partial void printButton (Foundation.NSObject sender) {
            NSPrintOperation p = NSPrintOperation.FromView(this.imgCell.ControlView);
            p.RunOperation();
        }

Really surprised how easy that turned out to be!

Here’s a generic way to use a webservice to send email, and it’s been tested with Amazon SES. Proxying email like this saves exposing your own IP address to recipients, to avoid problems with your ISP, or main hosting provider.

Here’s the code;

using System.Net.Mail;
using System.Text;
using System.Threading;
using System.Web.Services;

/// <summary>
/// Summary description for EmailProxy
/// </summary>
[WebService(Namespace = “http://emailProxy.org/&#8221;)]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
// To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line.
// [System.Web.Script.Services.ScriptService]
public class EmailProxy : WebService {

[WebMethod]
public void SendEmail(string smtpHost, string username, string password, int port, string to, string from, string subject, string body) {

var client = new SmtpClient
{
Port = port,
Host = smtpHost,
EnableSsl = true,
Timeout = 10000,
DeliveryMethod = SmtpDeliveryMethod.Network,
UseDefaultCredentials = false,
Credentials = new System.Net.NetworkCredential(
username,
password)
};
var mm = new MailMessage(from, to, subject, body)
{
BodyEncoding = UTF8Encoding.UTF8,
IsBodyHtml = true,
DeliveryNotificationOptions = DeliveryNotificationOptions.OnFailure
};
client.Send(mm);
Thread.Sleep(1000);
}

}
