How to control access the assemblies?

[RA]

Hi

I have a csharp assemblies that communicates between themselves. They are
not installed in the GAC. How can I limit access between the assemblies to
be only for those assemblies and not some other unknown assembly?

Thanks,
Ronen

Add a link demand to your classes that requires a specific public key for
assemblies that link to your class. Relace PublicKey with the public key
that you're requiring.
[StrongNameIdentityPermission(SecurityAction.LinkDe mand, PublicKey = "...")]
public class MeMeOnlyMe
{
}

The only problem with adding a public key and using this method is that
anybody can use that public key and can extract it from you assembly.
Normally if you want to do something like this only one assembly is
required, because two assemblies that can only communicate with each other
might as well be one assembly.

But you can always create a custom authentication scheme between the same
assemblies or set up a secure connection using sockets. Or do many things.
If you could post more about what you are trying to accomplish we might be
able to help you more.

Huh? Sure anybody can extract the public key, but they can only sign an
assembly with it if they also have the private portion - and presumably
you've kept *that* private.

Assembly factoring is orthogonal to the identity of the person(s) creating
the assembly. My current app has 5 developers and 20+ assemblies.
