I need to export private key from Windows store. What should I do if the key is marked as non-exportable? I know that it is possible, program jailbreak can export this key.

To export key I use `Org.BouncyCastle.Security.DotNetUtilities.GetKeyPair()` that exports key from `(RSACryptoServiceProvider)cryptoProv.ExportParameters(true)`. Exported key I use in `Org.BouncyCastle.Cms.CmsSignedDataGenerator` for CMS signature.

I need solution for .Net, but any solution will be useful. Thank you.
