I feel like if you get the title of Distinguished Engineer as a cryptographer, something has gone horribly wrong. #INDCCA

A bit over two years after starting to work on it... Go is officially FIPS 140-3 certified 💥 csrc.nist.gov/projects/cry... I am pretty confident Go is now one of the most—if not the most—seamless and complete FIPS 140-3 compliance solutions... with a single env var, out of the box.

Two papers came out last week that suggest classical asymmetric cryptography might indeed be broken by quantum computers in just a few years. That means we need to ship post-quantum crypto now, with the tools we have: ML-KEM and ML-DSA. I didn't think PQ auth was so urgent until recently.

A Cryptography Engineer’s Perspective on Quantum Computing Timelines

The risk that cryptographically-relevant quantum computers materialize within the next few years is now high enough to be dispositive, unfortunately.

Using an age keyserver as a demo, this article demonstrates how to add a transparency log to a centralized service step-by-step. We use Tessera for the tlog, VRFs for privacy, and the Witness Network. It all takes just 500 lines to integrate! The result of years of work making tlogs accessible.

Building a Transparent Keyserver

We apply a transparency log to a centralized keyserver step-by-step, in less than 500 lines, with privacy protections, anti-poisoning, and witness cosigning.

One month ago, I earned my master's degree in cybersecurity. Working on my thesis was deeply rewarding, and I received a final grade that exceeded any expectations I had when I began this journey two years ago. Thank you to all the great people who make cryptography open and welcoming to anyone.

A photo of me standing on a sunlit brick walkway, wearing a black suit and white shirt, smiling, and topped with a laurel graduation wreath. I am holding a bouquet (blue hydrangeas and red roses) and a red diploma folder. In the background are grass, trees, a streetlight, and parked cars.

Hand holding a dark red hardbound master's thesis against a plain white wall, with gold-embossed logos and text on its cover. At the top, the cover shows Università degli Studi di Padova and Dipartimento di Matematica logos. In the middle, the title reads "Fuzzy Searchable Symmetric Encryption: Design and Implementation of a Novel Scheme Toward Real-World Applications." Below the title is written "Master Candidate: Simone Ragusa", "Supervisor: Prof. Nicola Laurenti", and "Academic Year 2024/2025".
