Verifiable brute force strength Below are table of various projects that can completely exhaust n-bits of keyspace. In other words, counting completely and fully from 0 to 2ⁿ-1. This Gist implies no discussion about how this is relevant to quantum computing using Grover's algorithm, meet-in-the-middle or birthday attacks, or anything of the like. It's strictly a Gist about raw speed, measuring the result in bits. If you know of other noteworthy and verifiable brute force searching projects, please reach out to me on Mastodon, and reference this Gist. Fastest rates as of 2026-01-05 This is a table of the fastest rates collected from the rest of the tables below. Project 2ⁿ/sec. 2ⁿ/hr. 2ⁿ/day 2ⁿ/wk. 2ⁿ/mo. 2ⁿ/yr.
