I have an application in C++ that needs to transmit data securely via web services to our web server.
VPN was the first choice, but out network administrator informs us that we will not support the IPSEC protocols available on Windows Mobile.
Currently we have tried implementing a SSL connection, but found we don't have the libraries for that.
Alternatively, we have been trying PocketPutty to create a SSH tunnel, but that only has a GUI interface, and we're not sure how to get that to work via programming code.
Thank you
OpenSSL supports Windows CE.
SSL 2.0 has been supported since at least CE 5.0.
SecureBlackBox is also supported.

I tried to build a server for integrating the webrtc native APIs in an native app, but I am not sure about how the server should be configured, like the ICE/STUN/TURN, signaling, media server etc..
So far as I know is the open source project: https://github.com/priologic/easyrtc
Can anybody give some recommendations?
Thanks
In a WebRTC infrastructure, there are several things involved. The client part is written in JavaScript and runs on the browser.
But as you said it is a server side part. First there is a ICE/STUN/TURN server that it's used for a client to discover its public IP address if it is located behind a NAT. Depending on your requirements could not be necessary to build/deploy your own server, but use an already public (and free) existing one - here's a list. You can also deploy an open source one like Stuntman.
Then it comes the signaling part, used by two clients to negotiate and start a webrtc session. There is no standard here and you have a few options.
You can use an XMPP server with a Jingle extension. You can deploy an existing XMPP server, like OpenFire or Tigase
You can also use SIP, a protocol much more encountered for VoIP. You can use JAIN-SIP or SIP Servlets.
Or you can develop your own signaling protocol using something like websockets.
The server side options that I was giving you were Java based ones, but you can find similar for other infrastructures too.
STUN/TURN is required. Use public ones (not absolutely stable) or get a Ubuntu machine ans install from the source: https://code.google.com/p/rfc5766-turn-server/
Signaling is trivial. You just forward messages between peers. Just build a simple chat server.
Media server is whole different story and require sophisticated client-server configuration.
My web host has made my server more secure and is now requiring connection via FTP over SSL/TLS but they will not accept SSL3.0, only TLS1.0 or higher.
This rules out Dreamweaver CS6, Komposer, Microsoft Web Expressions 4.0.
Filezilla works, so all is not lost, but it makes it a two program process (develop in Dreamweaver, cross to Filezilla to upload)
Does anyone know of a Windows 7 program that can connect via FTP using TLS v1.0 or higher instead of SSL3.0
Any suggestions greatly appreciated
Cheers, Al.
I have found a program called CoffeeCup HTML Editor.
It connects using TLSv1.0
I'm sure there are others, but this is the first one I found that I got to work and I am using it now.
I'm trying to make my store app communication with desktop app through websockets.
I know we can make metro app as a client and do WinRT way of communicating over.
For the desktop server part, i'm planning to write a dll that will contain server code and receive metro texts being sent over.
Can someone please tell if this is possible and how to write server code in a dll and if so should we be using winhttp for wbesockets in server side ?
Windows Store (WInRT) apps are executing in a sandbox which isolates them from network communication with other applications on the local machine (localhost). That being said, this protection can be disabled using CheckNetIsolation.exe. Visual Studio automatically does the same for debugging purposes, allowing you to call e.g. a web service on your local machine during development.
As for the desktop side; to communicate with web sockets client, you can make advantage of WinHTTP. There's a working example on MSDN.
Keep in mind, though, that any application communicating with localhost will not be certified for Windows Store and will require several additional steps to install it:
The Windows Store application package will need to be sideloaded since it won't be published in Windows Store.
Any desktop component it communicates with will need to be installed separately the same way as any other desktop application.
Using CheckNetIsolation.exe loopback exemption will need to be added for the Windows Store app.
If you can avoid it, I definitely suggest you don't try communicating directly with a desktop application from you Windows Store app.
I need to implement a server running on Windows CE 5.0 that shall communicate on a secure connection. To implement a secure connection SSL looks like a good choice.
The Windows CE 5.0 Winsock implementation allows to implement all the SLL stuff using the Winsock Secure Sockets. But the problem is that the referred site states:
SSL does not support the following Winsock functionality ... "Calls to the accept function".
How can I implement a SSL secured server when accept will not work? What other options do I have to implement a secure connection to a Windows CE 5.0 device?
Edit: My current application implementation is in C++. So I would prefer an approach that use the Windows API or a C++ library.
We ported the Mentalis Secure Socket Library to the Compact Framework for when we needed SSL. It was fairly painless, though not without its bugs.
MatrixSSL supports Windows CE:
MatrixSSL™ is an embedded SSL and TLS implementation designed for
small footprint applications and devices. Available is a fully
supported, commercial version as well as an open source version that
is available for download. MatrixSSL allows secure management of
remote devices. Several secure embedded Web servers also use MatrixSSL
for their encryption layer.
MatrixSSL has been ported to operating systems including
FreeRTOS, Bare Metal, eCos, VxWorks, uClinux, eCos, FreeRTOS, ThreadX,
WindowsCE, PocketPC, Palm, pSOS, SMX, BREW, MacOS X, Linux and
Windows.
I want to create an application that acts as a vnc client which is connected to multiple servers at once. First and foremost, how do I access the VNC protocol in vb.net (make a client/server, output the display etc)? Second, how can a single client connect to multiple servers?
Thanks for the help! I take it there are no VncServer or VncClient components in the .net framework?
A .net vnc client library can be downloaded here. There are instructions in the documentation for creating c# and vb.net applications.
I don't know any component in the .net framework which can do this for you. My suggestions:
Implement one of the VNC protocols yourself in .net
Encapsulate a vnc client application.
Each time you start a client, it connects to a server, so in order to connect to 2 servers, start 2 clients.
