Entropy sources: My entropy cocktail recipe: took random words and numbers from people, has them, and concat put random symbols in between.
Time taken: ~ 20 hours
Side channel defenses: Running in isolation area (on dacha). Closed all the applications, services, and daemons on the laptop and switched off the connection to the internet.
Postprocessing:
- Rebooted the laptop, then transferred the files to an external hard drive, plugged that into a different laptop, and uploaded them to the remote server.
