Thanks for your comments, they clarified a lot.

I started from the most simple one and added some enumerations that are required by the classes, a patch can be seen in my github tree. They should go without any testing, I checked the values match values in .NET, but if someone else wants to check I wouldn't mind.


Next I should move to the Serializable classes CngKeyBlobFormat and CngProvider that are very similar to CngAlgorithm and CngAlgorithmGroup. I can probably also get the needed unit tests from there.

CngKeyCreationParameters, CngProperty, CngPropertyCollection and CngUIPolicy are also very simple classes but need their own unit tests. Then ECDiffieHellman, ECDiffieHellmanPublicKey and ECDsa classes are just abstract wrappers for the actual Cng classes.

Finally CngKey, ECDiffieHellmanCng, ECDiffieHellmanCngPublicKey and ECDsaCng all might need to depend on the actual elliptic curve implementation and are quite much trickier. I'll probably get back to it later, but if the first patch seems ok I'll continue forward. Of course any comments or suggestions are welcome.
