[Enhancement] Combine camera entropy with dice roll entropy

[nervetrip]

I would use Krux for seed generation if it supported combining multiple sources of entropy. Right now I don't use it for seed generation. Maybe if I had a wall of lava lamps I'd feel safer. And yes, I know I'm overly paranoid. 😆

This would mean adding additional external entropy on top of the camera entropy. Allow users to add dice rolls or coin flips to the camera entropy. Combining multiple sources of entropy is best, as I don't trust any seed generation implementation or random number generator on its own.

Coldcard supports this. It generate RNG entropy for a good starting entropy. Then you can add dice rolls to it. That way, even if the CC's RNG is exploited at some point, seeds are still safe. It is also safer than only using dice rolls (rolling too few dice is very dangerous) since they are combined with the entropy of the RNG.

Currently, I pick CC to generate seeds over Krux any day. But with this enhancement, I would use Krux.

Hi, this suggestion seems to align with the seedXOR feature suggested here: #384
