I'm glad to see this issue. I have had similar needs recently, involving some domestic application scenarios. When using domestically produced hardware, in many scenarios we hope to use password libraries that have passed the commercial password inspection of the National Password Management Office. This requires the password library of the entire system to be domestically produced. This has been supported in domestically produced hardware and CSV virtualization technology, but it doesn't seem like rats-tls has similar support yet. This makes it a weak point. I am also trying to make some modifications, but it is not very smooth because I don't have enough knowledge of the entire rats-tls project. I hope we can make some plans, explore together, and learn together.
