The NGRAVE "Perfect Key" is a combination of two parts that are mathematically combined into a single key:
- a random part of bits that is generated by the chip;
- a random part of bits that comes from your biometrics (your fingerprint) and your surrounding light (proven to be a powerful source of randomness).
When this key is made, you as a user can still change parts of the key in a smart interaction process. That way, you can be sure that even NGRAVE has no idea of what the value of your key might be.
