How do I find out my private key?

Based on a chip that generates a private key during the AngPao creation process, using a hardware random number generator. The entropy for the random number is taken from the chip’s physical sensors. The key never leaves the chip in an unencrypted state or after it is activated. The chip’s primary purpose is to keep the key safe and secure.
This means that no one can ever find out your private key. The secret is safe, even from you the owner.
