1. Peter (as switck) wrote the broken #ifndef guard in libngu (Jan 2021).

2. Peter (as doc-hex) integrated libngu into #Coldcard firmware and changed seed generation to use it (March 2021).

3. The combination caused ngu.random.bytes() → MicroPython Yasmarang software PRNG (seeded from UID + timers) instead of the hardware TRNG.

Result: seeds with ~40 bits effective entropy on Mk2/Mk3 (and ~72 bits on later models that mixed in some secure-element data), which "attackers" later brute-forced.

I never imagined my life could change this much until Craig came into the picture. Turning my $10,000 into over $90,000 through crypto and stock trading gave me more than financial freedom—it gave me hope and confidence. I finally walked away from my 9-to-5 job, and the journey is still growing. F...

I invested $30,000 and grew it to $95,000 with Mr. Craig's guidance. What impressed me most wasn't just the outcome but the knowledge I gained along the way. His teaching is straightforward and focused on long-term improvement. I highly recommend checking out his page if you want to become a better ...
