How to create your own private key?


i am wondering how it is possible to create your own private key.

I know, that the Chia Application allows the creation of a private key, but that isn’t what I want. With the app creating my private key, I have no control over the key. I want to create my private key by myself, like I can to with ETH, for example. So the questions that I have are:

  1. Which algorithm does Chia use for the key creation?
  2. How can I import my own private key into the application?
  3. How do I export the existing private key and reimport it?

Thank you very much in advance for your answer.
