篡改强大的命名程序集有多难？

Question

Assume I have a .NET assembly which is strong named. Only I have access to the private key. I then distribute the assembly to some client system.

How hard is it for the client to modify the assembly? Ie: what would they need to do to modify my assembly?

Answer 1

强命名不会阻止修改程序集，但它确实会阻止其他引用强命名程序集的应用程序无意中使用修改后的版本。

Answer 2

It's no different from modifying a non-strongly typed assembly. The only real difference is that they would have to run the strong name utility (sn.exe) in order to use the modified assembly.

Answer 3

As others have said, its very easy.

One technique you can use is to use the public key (or token) of your assembly to encrypt important information (such as algorithm parameters, connection strings, etc) in your assembly. This way if the public key has been changed or removed, the decryption will fail and your assembly would no longer run correctly. Obfuscators such as Crypto Obfuscator use this technique as one part of the protection.
