Show HN: Rscrypto, pure-Rust crypto with industry leading public benches

A new project called rscrypto arrived waving a very big flag: one Rust-based security library to do nearly everything, from passwords to signatures, while staying small, portable, and apparently very, very fast. The creator says the whole point is avoiding the usual mess of different tools for different devices, plus less dependence on outside system libraries. In plain English: one box of security parts instead of a junk drawer full of mismatched pieces.

But the real fireworks were in the comments, where the crowd did what the internet does best: turn a product launch into a live cross-examination. One skeptical commenter zoomed in on the phrase “constant-time” like a detective spotting a typo in a ransom note, basically asking, “Cool claim — so which parts are not safe in that special timing-related way?” Another wanted the full backstory: where did the speed gains come from, why build a new library at all, and why not help existing projects instead? Ouch.

Then came the most deliciously brutal jab: the readme has “strong LLM smells.” Translation for normal people: it reads like it may have been polished by AI, and that instantly put the community into side-eye mode. The subtext was clear: if the sales pitch feels machine-made, people will start asking whether the code is too. So yes, the benchmark bragging got attention — but the real show was the classic open-source drama of speed vs trust, bold claims vs receipts, and builders vs skeptics.
