I wrote an article in a similar vein a month ago: Becoming physically immune to brute-force attacks.

Stuffing the planet into a 100%-efficient furnace isn’t enough to crack a 256-bit key.

I’m building off those ideas in what will be a little collection of programs that measures and generates passwords given physical constraints of a brute-force attacker (energy, power, mass, etc). The collection isn’t really a collection yet; it currently contains almost one complete program: https://sr.ht/~seirdy/MOAC

Edit: URL typo

we can determine quite accurately how much heat would be released by a computer that brute-forced a 128-bit cipher. The results are profoundly silly: it’s enough to boil the oceans and leave the planet as a charred, smoking ruin.

I wasn’t expecting that haha. :D
