Is it possible to get private assembly key?

Question

Hi,

Is it possible to get private assembly key in .NET using only public token?

Thanks, Alexey Z.

No, because otherwise signing assemblies would be pointless.

The developer of the Assembly keeps their private key secret so that any user of a signed Assembly can be sure it comes from who it claims to be from, preventing spoofing attacks.

If it becomes practical to calculate private keys from public keys a lot of security measures - not just the signing of .NET Assemblies - will become worthless overnight.
