GitHub - DavidEGrayson/ruby_ecdsa: This gem implements the Elliptic Curve Digital Signature Algorithm (ECDSA) almost entirely in pure Ruby.

A (Relatively Easy To Understand) Primer on Elliptic Curve Cryptography

Elliptic Curve Cryptography (ECC) is one of the most powerful but least understood types of cryptography in wide use today. At CloudFlare, we make extensive use of ECC to secure everything from our customers' HTTPS connections to how we pass data between our data centers.

ATProto Ruby SDK

A set of libraries for building and accessing AT Protocol services in Ruby

Thomas Larsen on Twitter / X

We found another cyberattack by internal OpenAI agents, this time targetting @rubygems. They: 1) gained arbitrary remote code execution on rubydoc. 2) developed a novel exploit to steal user API keys (but we do not know if they succeeded). They used package names including… https://t.co/IxqLAto2XA pic.twitter.com/48BW4lmg76— Thomas Larsen (@thlarsen) September 11, 2026

The Pulse: RoR creator sparks new “death of coding by hand” debate

37signals – the creator of Ruby on Rails (RoR) – moves over to agents generating nearly all its code. Also: Amazon and Meta struggle to hire engineers, code reviews will probably also go away and more

Composite ML-DSA for use in X.509 Public Key Infrastructure

This document defines combinations of US NIST ML-DSA in hybrid with traditional algorithms RSASSA-PKCS1-v1.5, RSASSA-PSS, ECDSA, Ed25519, and Ed448. These combinations are tailored to meet regulatory guidelines. Composite ML-DSA is applicable in applications that uses X.509 or PKIX data structures that accept ML-DSA, but where the operator wants extra protection against breaks or catastrophic bugs in ML-DSA, and where EUF-CMA-level security is acceptable.

In the open source world, the popular programming language Ruby is experiencing a fierce controversy over critical infrastructure control.

ATProto in Practice #1: Identity

I’m starting a new blog post series that I’ve named “ATProto in Practice”. I want to go through some practical tasks that you’re likely to need when working with the protocol, using Ruby and my Ruby gems for the examples. These will (hopefully) be a bit shorter than my standard book-length blog posts here 🫠
