Hi, thank you

Is it possible to use this namespace as standalone? eg: Do I have to install OpenCF? Do you have any sample

My first goal is to use .NET CF only

tks & regards

You have a couple of options if you don't want to deploy the entire Smart
Device Framework. You can either deploy just the OpenNETCF.dll which
contains the Cryptography namespace, or you can take the source code for the
functionality you require and build your own custom dll.
More detail on the three deployment methods here:-

Casey's original article on Cryptography has a sample smartphone
application.

the above posts tell you how to get crypto alone.

for web services, you should use WS-Security standard to encrypt the
messages:

or just use SSL

or you could use your own ad hoc WS encryption like this:
