[Cryptography] Lava Lamps Can Actually Create Secure File Encryptions - Here's How

[Aram Perez]

As far as data encryption goes, you wouldn't expect a bunch of lights to help secure anything — certainly not some '70s-style lava lamps. But as it turns out, the exact opposite is true. Cloudflare, the major infrastructure company that props up large portions of the internet, actually uses 100 lava lamps for SSL encryption. The blueprint, integral to secure encryption, is randomness. The encryption "key" is what unlocks the data for secure systems and allows it to be read. By keeping keys random, you can essentially keep would-be hackers guessing, preventing unauthorized parties from accessing the systems or data the encryption protects. This is a lot like how encrypted messaging apps work, minus the psychedelic decor.
