EVA Locker is a next-generation, client-side Zero-Knowledge cloud encryption platform designed to make uncompromising privacy effortless for everyone.
Built around a strict Zero-Knowledge and End-to-End Encryption (E2EE) model, all cryptographic operations occur directly in the user's browser via WebAssembly and Web Crypto API. Your master keys and files are encrypted client-side using AES-256-GCM and derived with Argon2id (Memory-Hard KDF) before ever leaving your device. It is mathematically impossible for our servers to read, decrypt, or inspect your data.
Under the hood, our high-performance backend infrastructure is built with Bun, ensuring ultra-low latency, blazing-fast streaming, and resilient data storage. While the internal engineering is advanced, the user interface remains intuitive, modern, and accessible to non-technical users alike.
The core architecture is already operational and entering its final polish. If you believe in accessible, independent, and verifiable privacy tools, join our Patreon to support development, infrastructure costs, and the upcoming public launch.

Finally, a platform that takes zero-knowledge architecture seriously instead of treating it like a marketing buzzword. The client-side cryptographic pipeline is rock-solid—key derivation and local encryption execute cleanly without degrading UI responsiveness. It strikes the exact sweet spot between uncompromising cryptographic guarantees (true E2EE, zero server-side trust) and a seamless, modern developer experience. Highly recommended for teams handling sensitive telemetry or proprietary datasets. It’s a shame it was set up on Netlify, because if there’s too much traffic and you run out of credits, you have to wait
We’re delighted that you like our app.
As for Netlify, we’ve been using it as a stopgap – that is, it certifies the keys – but of course, as the project grows, we’ll move to a proper domain.
It's incredible how intuitive and easy to use this app is, even though at first I didn't know some of the terms written on some pages. Luckily, in the end I managed to find an alternative to many software that you really need to have some expertise to use.
That is why we have chosen this simplicity precisely to make our software accessible to everyone
This project is very easy to use, then the plasma graphics are beautiful 🔥
We’re pleased that you like the graphics
It’s not bad considering how well it’s been optimised; I’d recommend it for its speed and security 😊
Thank you for your review ❤️
I really like the Plasma interface, and especially how smooth it is even beyond the PWA’s main function. 😁
Thank you for your review 💕
