Ekko – post-quantum E2EE layer for Instagram, WhatsApp, Telegram Web

In plain words

Ekko is a browser extension that adds post-quantum end-to-end encryption to existing messaging platforms like Instagram, WhatsApp, and Telegram Web. Designed for privacy-conscious users concerned about data harvesting and corporate access to communications, it encrypts messages without requiring users to switch to alternative messengers. The extension allows people to maintain their existing social networks while gaining additional encryption security on top of closed-source platforms.

From the sources

Ekko encrypts messages locally before they travel through the apps people already use, so you can keep conversations private without asking everyone to switch messengers. Join early access.

Your DMs are not as private as you think. Ekko seals them with post-quantum encryption inside Instagram, WhatsApp, Telegram and the apps you already use. Claim your handle before someone else does.

Post-quantum encryption, right where you already type. No new messenger, and nobody to talk into switching. Animated demonstration: Ekko seals a one-to-one message on the sender's device and opens it in the recipient's chat. Across all your messengers. In your browser today. In your keyboard next. Keys are generated on your device, sealed by your passphrase. Grab @you , or stay completely anonymous. Your private key never leaves your device. Ekko only publishes the public key people need to reach you. It never uploads the key that opens your messages. The mark sits at the end of the box. It names who it is sealing to, checks their key, and the words leave encrypted. In your browser today,…from useekko.app

In the maker’s words, at launch

Hi everyone, I am a big privacy activist and the amount of privacy concerns in the internet with the discussions around European Chat Control, Meta removing e2ee in Instagram and corporations harvesting personal data for AI training is on the rise. The closed source social media companies keep managing and storing…

  This is a project I made to learn more about crypto. I've also written a [post](https://vaktibabat.github.io/posts/ecurvechat/) that explains all the crypto concepts and algorithms used in the project, and how I implemented them. I'd be very glad for any feedback about both the code and the post :)

  I replaced a $120k bowling center system with $1,600 in ESP32s▲2,935

  I might be the only SRE on Earth with his own bowling center. It's a more in-depth gig than you'd think. My family and I bought an abandoned 8-lane bowling center in the rural mid-west. In our small town there weren't many recreation options for families. You've heard of a food desert? This is an R&R desert. It had been abandoned for a good reason. The roof leaks, the electrical system was constantly surging, and my 70-year-old bowling equipment (still) doesn't work perfectly. The system that keeps your score is particularly interesting to me. It's the thing you watch during your game, but…

  Bento - An entire PowerPoint in one HTML file (edit+view+data+collab)▲1,033

  Over the past few months, our team has been building more and more slidedecks using web frontend technologies with coding harnesses like Claude Code, but a common complaint is to make even small edits we need to edit the code either manually or via the harness. To avoid this loop, I ended up creating Bento, a single HTML file with everything you need in a slide tool including animations and shared editing. There's no install or cloud login, everything works offline. The default deck is around 560 KB and it doesn't need to fetch anything once you got it. Open it in a browser and then you can…

  Getting GLM 5.2 running on my slow computer▲937

  A few days ago I found myself trying out GLM 5.2 and was really positively impressed. The capabilities and security I was getting from this LLM are similar to those I've gotten from models like Claude or GPT, and this really surprised me. But then I thought, "I wonder how it would work on a normal computer like mine," and above all, "I wonder if it would work without going into OOM on a computer like mine." So I started working with the help of agents to test this possibility. I started converting the model to int4, understanding MTP usage, and if possible implementing DSA for long context.…

  OpenSEO▲928

  Hello! For the last 2 months, I've been building OpenSEO. It's a user friendly UI wrapping the DataForSEO API which has high quality SEO data for keywords, backlinks, AI SEO and competitor research. Instead of paying $100+ per month, you buy DataForSEO credits and pay only for usage. The coolest thing about the project so far has been hearing about what people are building on top of it. People are using coding agents to quickly integrate with Google Search Console, Google Ads and building their own AI SEO and reporting features. Many were already building their own custom solutions around…
