The pattern of downloading and executing installation scripts without verifying them has bothered me for a while. I started messing around with a way to verify the checksum of scripts before I execute them. I've found it a really useful tool for installing things like Rust or Deno. It's written entirely as a shell script, and it's easy to read and understand what's happening. I hope it may be useful to someone else!

Made this using Power BI and the Crypto Watch API. Started making this in November 2021, but never got around to publishing it, so that is the reason for the 'FOMO' in the title - probably a good thing if you 'missed out' on the crypto hype late last year. Now it serves as a way to see how much you 'saved' by not putting in money. Hope someone finds it fun!

I built this machine so I could generate Bitcoin keys that I could trust. Air-gapped and simple to use and understand (mechanical). The Satoshi 9000 demo: https://youtu.be/bJiOia5PoGE The key value proposition of the machine is that it generates analog randomness in the physical world and converts it into digital (1’s and 0’s) randomness. Seamlessly. But it occurs to me that it may have other uses beyond crypto keys for your own use, such as: * Randomized clinical trials. Clinical trials need a high degree of transparency for ethical reasons; also, for legal reasons should it…

LoopMix128 is a fast C PRNG I wrote for non-cryptographic tasks. GitHub (MIT): https://github.com/danielcota/LoopMix128 Highlights: * ~0.37 ns/value (GCC 11.4, -O3 -march=native), 98% faster than xoroshiro128++ and PCG64. * Passes TestU01 BigCrush & PractRand (32TB). * Guaranteed 2^128 period. * Proven injective (192-bit state) via Z3 SMT solver; allows parallel streams. * Core requires only stdint.h. Seeking feedback on design, use cases, or further testing.

Hi HN, I made Keepr, a simple offline CLI password manager for developers who prefer keeping secrets local and working entirely in the terminal. Everything is stored in an encrypted SQLCipher database, protected by a master password. A time-limited session keeps the vault unlocked while you work, so you don’t need to re-enter the password constantly. Keepr never touches the network. It includes commands to add, view, search, update, and delete entries, plus a secure password generator and clipboard support. Technical details: - AES-256 via SQLCipher - PBKDF2-HMAC-SHA256 (1.2M iterations) for…

Wrote this to learn more about the `chumsky` parser combinator library, rustyline, and the `ariadne` error reporting crate. Such a nice DX combo for writing new languages. Still a work in progress, but I thought I'd share :)
