Cryptography A Researcher Just Broke a 15-Bit Elliptic Curve Key on a Quantum Computer. Here's Why That Should Concern You. On April 24, 2026, Project Eleven awarded 1 BTC to researcher Giancarlo Lelli for breaking a 15-bit elliptic curve key on publicly accessible quantum hardware. Here's what that means, why the trajectory matters more than today's number.
Web Servers How Authentication Actually Works Authentication is a cornerstone of contemporary applications. Virtually every app demands user login, identity verification, and secure sessions. Though it's ubiquitous, many developers implement authentication without a complete understanding of it's inner workings. This article breaks down authentication step-by-step, explaining the core concepts used in most
Cybersecurity Google and Cloudflare Set a 2029 PQC Deadline. The Rest of Big Tech Did Not. Two papers dropped at the end of March. Both said the same thing in different ways: the quantum threat to elliptic curve cryptography is closer than we thought. How close? The kind of close that made Google set an internal deadline five years ahead of what the US government asked
Artificial intelligence Claude Mythos Hacked Every Major OS, Escaped Its Sandbox, and Emailed a Researcher Eating a Sandwich. We Need to Talk. I use AI as a tool. I'll say that upfront. Claude helps me write frontends faster. It handles search queries that Google stopped being useful for three years ago. I hand it boilerplate I've written by hand a thousand times and I get time back. That&
Cryptography Featured Implementing RSA, AES-GCM, and a TLS 1.3 Handshake from Scratch in Python A deep-dive into the full cryptographic stack powering every HTTPS connection — RSA-OAEP, AES-GCM, ECDHE key exchange, and a working TLS 1.3 handshake simulation, all built in pure Python from first principles.
Cybersecurity Your HTTPS Is Toast (But Google Has a Plan): Merkle Tree Certificates and the Post-Quantum Web RSA-2048 can be broken with fewer than 100,000 qubits. What that means for TLS, certificate infrastructure, and the post-quantum transition already underway.
Cybersecurity What is Encryption? The Math That Keeps Your Data Private Encryption transforms readable data into unreadable ciphertext that only someone with the right key can reverse. It's what makes HTTPS, messaging apps, banking, and password storage work. Here's how it actually functions.
Cryptography Understanding & Creating RSA Digital Signatures In this article, I am going to show you what to learn from the first articles to turn it into real world, production safe usage. This article is going to cover one last major concept before we get into the real world usage of RSA: create unforgeable digital signatures. The
Cryptography Implementing RSA from Scratch in JavaScript Please note that it is essential for me to emphasize that the code and techniques presented here are intended solely for educational purposes and should never be employed in real-world applications without careful consideration and expert guidance. At the same time, understanding the principles of RSA cryptography and exploring various
Cryptography Understanding How to Use Cryptography in Java I will explain the Java Cryptographic Architecture (JCA) for a better understanding of how it works. The JCA is designed to simplify the creation of protocols like encryption, hashing, digital signatures, and key generation for Java developers Now let's take a look at how the API works for
Cryptography Featured RSA in Python Part 3: Defending Against Side-Channel and Timing Attacks Learn how timing attacks can extract RSA private keys from a working implementation, and how to defend against them with constant-time operations and blinding techniques in Python.
Cryptography A Small Introduction to RSA Encryption & the Mathematics RSA Encryption has always been amazing to me. It allows you to publish an encryption key – also known as e – without having to compromise your decryption key – known as d. One amazing feat that I find the most interesting is that generally in practice that e is usually always the
Cryptography Featured RSA in Python Part 2: Random Prime Generation and Text Encryption Extend your Python RSA implementation with 1024-bit cryptographically secure random prime generation using the PWS primality test, plus full plaintext encryption and decryption.
Cryptography Featured Implementing RSA in Python from Scratch Build RSA encryption in Python from first principles. Covers the Extended Euclidean Algorithm, modular exponentiation, key generation, and working code you can run.
