Hi,

For my diploma thesis, I'm trying to establish a connection between a
webservice and a PocketPC and to exchange RSA encrypted data. Since I'm
using C# and .net CF does not support the Cryptography namespace, I'm
using the OpenNETCF implementation.

Everything works, but I have a question; currently, my PDA application
reads the server's public key from a text file (which is not nice but
works). However, for secure replying to the PDA, I'd need to store a
private key within the PocketPC. Storing private keys in textfiles is
obviously not the way to do it - MS recommends to use a keycontainer
(whatever that is?). OpenNETCF does not support the CspParameter class
which is needed to work with keycontainers.

Therefore, does anybody know any other way to create a keycontainer or
otherwise store a private key securely on a PocketPC? Or did I get
something terribly wrong?

Thank you for any hint!

Regards,

Roland
