.NET - providing sign certificate with 3rd party libraries

I want sell some .NET library and I want provide "edition" with full source c开发者_如何转开发ode.

Should I provide the sign certificate with the source code or should users-developers sign it with their own?

IMHO you should not provide your private key because that's what guarantees that the code is written by yourself. If you provide your key it's like giving your identity to others and you may be responsible for some bad code you never wrote.
