Add vnsh — Encrypted Sharing extension

[raullenchai]

Summary

• Adds vnsh — Encrypted Sharing to the extensions list
• vnsh is a zero-knowledge encrypted sharing tool for developers: AES-256-CBC encryption happens entirely client-side, the server never sees keys or plaintext, and links auto-expire in 24 hours
• Open source (MIT) — GitHub | Website

Details

vnsh solves the "Context Injection" problem in LLM workflows by letting developers securely pipe sensitive local context (logs, diffs, configs, images) into AI agents via ephemeral, encrypted URLs. The Chrome extension provides a browser-based viewer that decrypts content purely on the client side using the key embedded in the URL fragment (which is never sent to the server).

Key privacy properties:

• Zero-knowledge architecture — the server only stores encrypted binary blobs and never sees decryption keys
• Client-side encryption — AES-256-CBC encryption/decryption happens in the browser via WebCrypto
• Ephemeral by design — all shared data auto-expires after 24 hours
• No analytics or tracking — strict Content Security Policy, no external scripts
