Hi everyone, I wanted to share a project I've been working on called SHUNYAKEY. It is an enterprise-grade, browser-based file and text encryption vault designed with a strict Zero-Trust approach. The application processes absolutely everything locally on your device meaning you can literally turn on Airplane Mode and use it safely. Zero data ever leaves your device. Live App & Source Code
Live Tool: https://snigdhosaha.github.io/sh...
GitHub Repository: https://github.com/snigdhosaha/s... Key Features & Highlights
Gold-Standard Security: Uses robust **AES-256-GCM** authenticated symmetric encryption via the native browser Web Crypto API.
Brute-Force Protection: High-security key derivation with **500,000 iterations by default (customizable up to 1,000,000).
Smart Large File Support (Chunked Mode): Handles massive files smoothly without crashing your browser window.
Custom Extension: Encrypted files safely export under a unique, proprietary .KALADRI file extension.
Zero Dependencies: Built entirely with pure vanilla HTML, CSS, and modern JS. No third-party servers or tracking. I would love to get your thoughts on the UI layout (themed around the defensive concept of Chakravyuh), code performance, or any edge cases you might find. Let me know what you think! Thank you.
