http://msdn.microsoft.com/en-us/library/ms229943%28v=VS.90%29.aspx

I've created a certificate, but when i run the program i have this error in the Decrypt method: "Unable to retrieve the decryption key"

I've read somewhere that there is a bug in this sample because the Encrypt method don't save the decryption key. The problem is that i don't understand how can i resolve the problem.

Can you help me please?

The crypted Xml obtained is:

I suppose the problem is that doesn't exists the keyName.

I've generated the certificate as: makecert -sk Abc -n "CN=Abc" -sr localmachine -e 06/22/2011 Abc.cer
