Store private key in assembly

[Guest Cuervo]

Hi! I want to know if there's any way to store a private key into an

assembly. I want to encrypt the comunication between

COM object and .Net object and to do this I want to use a simetric

algorithm, and both objects need to know the private key.

Using Reflector tool is very easy to know the private key.

How can I protect this information inside the assembly????? Code ofuscation

is the unique way to protect the key????

Thanks
