ssl certificate installation - wp 8.1 SL - silverlight

I've installed ssl certificate (which I downloaded from a webbrowser) via email on the device. Unfortunately, after the installation I still can't open the page in IE without warning ('It looks like the security certificate wasn't issued by a trusted certificate authority...').
I have to install my custom certificate properly, because without it I can't provide https connection between my wp 8.1 silverlight app and my web service. I tried .p7b, .peb, .cer and .cert certificates.
Any suggestions?

Untrusted certificates only work for email inboxes, not for apps. Either use HTTP or a paid cert.

Google API certificate issue via Restful Adapter

We are facing a SSL certificate issue while executing Token create Interface from SAP side.
For that while troubleshooting we got new 3 SSL certificates from SAP chain verifier, for this please find attached screenshot.
We downloaded those certificates and found out that the Root certificate is not trusted, also the intermediate certificate is different as per chain verifier. We are attaching all certificates in the zip file, please check.
If possible can you please provide a valid SSL certificate for Google token create API. So we can resolve this issue.

How to get corporate SMIME certificates automatically into Mozilla Thunderbird?

If I use the corporate Outlook, I can choose to enrypt email messages without manually managing certificates.
In Thunderbird, I have to download and import a certificate for each recipient.
Is there a possibility to let Thunderbird download X.509 certificates (.cer files) from the same central place as Outlook does?

How to fix codenameone ios push error : P12 password is missing

I am getting this error while pushing notifications to iOS device from server:
Exception while generating certificate data, probably P12 password is missing: java.lang.IllegalArgumentException: Passwords must be specified.Oracle Java SDK does not support passwordless p12 certificates
I am sending all required parameters including the P12 certificate url & password provided by CN1.
How do I diagnose or fix this issue ?
The P12 certificate was generated using the CN1 wizard and I got an email with a link to it and the password. The push request is sent from a ASP.Net MVC application running on IIS web server. Android requests sent from the same server work just fine.

Is it possible to use SSL with a custom domain on app engine without own certificate?

I have an app engine app and I enabled SSL for it (without an own certificate) and it works for the appspot-url like https://myApp.appspot.com. Now I want to use my custom domain like myDomain.com with SSL (e.g. https://myDomain.com). Is this possible without an own certificate like with the appspot domain? I followed this guide (https://developers.google.com/appengine/docs/ssl?hl=de) and it talks about uploading a certificate. Is that an optional or a mandatory step?
Because if I try to access my domain, I always get an SSL error
Uploading a certificate is mandatory if you want to use SSL for a custom domain. You can find details on SSL handshake at [1].

Is it possible to use client certificates with HTTPS requests from Windows Phone 7?

I need to invoke a REST-based service from Windows Phone 7.
The service only accepts the request if the following conditions are satisfied:
The request must happen over HTTPS/SSL
The request must be authenticated with a client X509 certificate
I don't control the service, so I can't change the authentication requirements.
On the full framework, we can do things like this:
HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(uri);
request.ClientCertificates.Add(accessCertificate);
However, the ClientCertificates property isn't available in Silverlight 4, and neither do any of the X509 classes from the System.Security.Cryptography.X509Certificates namespace seem to be available.
Is it really impossible to make Client Certificate-based HTTPS requests from Windows Phone 7?
Client certificates are not supported by the 3rd party WP7 SDK currently.
Confirmation here for your reference.
Problems with client certification authentication on WP7
Whilst it's possible to install certs on the device through email (referenced in an exhcange integration solution), your app won't use them.
There are only 2 ways to install 3rd party certificates on the device and neither can currently be done through code:
Installing certificates via Windows®
Internet Explorer®
A certificate can
be posted on a website and made
available to users through a
device-accessible URL that they can
use to download the certificate. When
a user accesses the page and taps the
certificate, it opens on the device.
The user can inspect the certificate,
and if they choose to continue the
certificate is installed on the
device.
Installing certificates via email
The certificate installer on
Windows Phone 7 supports .cer, .p7b,
and .pfx files. When installing
certificates via email, make sure your
mail filters do not block .cer files.
Certificates that are sent via email
appear as message attachments. When a
certificate is received, a user can
tap to review the contents and then
tap to install the certificate.
Typically, when an identity
certificate is installed the user is
prompted for the passphrase that
protects it.
You'll have to get the user to perform one of these actions before the app will work with the certificate.
From Windows Phone 7 and Certificates_FINAL_121610.pdf
So you can us oAuth for authentication and pass the token in the request header. If you check out acs.codeplex.com you can see how this is done using the Azure ACS system. I realize you may not be using Azure, but the reference app may help. I would also search for oAuth and Windows Phone 7, I have found a few examples that way too.
As far as SSL, you should be able to do that through the browser with out any issue. You can also open any https Url using an HttpWebRequest, etc.
