How do lava lamps help with encryption?

Lava lamps are used to generate truly random numbers, which are essential for encryption. Cloudflare's 'LavaRand' system captures the unpredictable movement of lava lamps and uses it to generate random numbers. This randomness is crucial for creating secure encryption keys and nonces. The use of physical phenomena like lava lamps provides a high level of entropy, making it difficult for attackers to predict the generated random numbers.
