Entropy source: Flux counts from the bright star Betelgeuse that has been displaying anomalous fading and unpredictable patterns. Aggressive keyboard mashing.
Time taken: ~15-20 hours
Side channel defenses: Peformed ceremony on a USB boot Kali Linux. Directly transcribed flux counts of the star, never recorded.
Postprocessing:
- Deleted challenge and response files.
- Erased Kali Linux session
