Beamsplitter – Hash function that uses only S-boxes
:gem: Beamsplitter - A new (possibly universal) hash that passes SMHasher. Built mainly with a random 10x64 S-box. Also in NodeJS - DO-SAY-GO/beamsplitter
Beamsplitter – Hash function that uses only S-boxes launched on January 18, 2020 with 18 votes, #745 of 3,486 launches that month and more than 75% of that year's launches. The site was still online in September 2026, 6 years on.
In plain words
Beamsplitter is a cryptographic hash function that relies exclusively on S-box operations for its computation. Launched in 2020, it is designed for developers and cryptography enthusiasts interested in alternative hash function architectures. The implementation is available on GitHub. The approach of using only S-boxes distinguishes it from conventional hash functions that typically employ multiple cryptographic primitives and operations.

Hey folks. Last year I was fortunate enough to sign a deal to write a book with my favorite technical publisher, The Pragmatic Bookshelf. When I started out as an Engineering Manager many years ago, I found that there wasn't a huge amount of material that specifically and practically helped me understand how to do my job. When you learn to program there's all of these amazing tutorials, examples and guides, but what was there for new managers? In response to this, a couple of years ago I started a blog over at https://www.theengineeringmanager.com which got a decent amount of…
