aas-n/reauthx ? reverse-engineered prompt

Build me a small Python security testing tool based on krbrelayx that adds an optional bypass mode for SMB signing checks, so I can test whether a target still accepts a relay when signing is enforced.

I want it to work like the existing relay flow, but with one extra flag for the bypass, plus the helper scripts for checking the target, creating the DNS name, and doing the cleanup. Keep it simple and practical, with a clear README that explains how to install it, what the new flag does, and a basic end to end example using a test lab. If you need to, look up the current docs for any dependencies or related tools online.
