VeraCrypt Done Right: The Practical Guide That Prevents Lockouts, Data Loss, and False Confidence
VeraCrypt is easy to use badly. You can choose an unnecessarily complicated cipher cascade, forget a custom PIM, leave the only copy of a keyfile on…
How AI could make it harder for governments to use hacking tools
AI is proving effective at finding and exploiting vulnerabilities. Some say this will make it harder for governments to use hacking tools and spywar…
A Secure and Efficient Image Encryption Scheme Based on Chaotic Systems
Chaotic systems have become one of the most practical foundations for image encryption because they generate sequences that are deterministic yet be…
Going Dark: Why Law Enforcement Hacking Is the New Surveillance Frontier
Going Dark: Why Law Enforcement Hacking Is the New Surveillance Frontier A provocative essay by cryptography engineer Matthew Green titled "Going Da…
Foxy Mail Wire: an open format for compressed & encrypted email
Internet mail still moves as MIME over IMAP and SMTP. That’s fine for delivery — bad if you want smaller messages or real end-to-end privacy of the…
Off-the-Record Messaging: Where Deniable Encryption Started
In 2004, three researchers published a paper with a pointed subtitle: "Why Not To Use PGP." Their argument was that encrypting instant messages with…
TLS Interception: How Corporate Proxies Read Your Encrypted Traffic
The padlock in your browser tells you the connection is encrypted. It does not tell you who is on the other end of that encryption. On millions of c…
rclone crypt: encrypt files client-side before they touch any cloud
If you want files encrypted before they ever reach a cloud provider — so the provider only ever sees ciphertext — rclone crypt is the simplest tool…
How We Encrypt X Auth Tokens: AES-256-GCM in Practice
When you build a tool that stores authentication tokens for other people's social media accounts, you have exactly one job before anything else: mak…
How I built an E2EE chat in Go + React (with AI agent support)
🚀 Try it now: Open the Arthas web app — create a room, share the code, chat with E2EE. No signup needed. TL;DR — Try It in 2 Minutes No signup requi…
laravel-crypto: libsodium, no compromises, and per-user encryption
Laravel's default cipher is AES-256-CBC . That is a 25-year-old design with no built-in authentication — the MAC is bolted on separately by the fram…
EU Chat Control: What Client-Side Scanning Actually Means for Encryption
The EU's proposed Chat Control regulation would require messaging providers to scan your messages for illegal content before encryption, on your dev…
Matrix: The Open Protocol for Federated Encrypted Messaging
Signal works well when everyone involved trusts the same company. Matrix is built for the case where they don't — where organizations want to run th…
Building an Experimental TypeScript Cipher Inspired by 8 Dimensions
Over the last few days, I started an experimental study on cryptography with the goal of better understanding concepts such as symmetric encryption…
