FileShot.io is an open-source tool that implements browser-side AES-256-GCM encryption for file sharing — might be worth listing under applied cryptography or tools.

The encryption model:

Files are encrypted entirely in the browser using the WebCrypto API (AES-256-GCM)
A randomly generated key is appended to the URL fragment (#) only — never sent to the server
The server stores only ciphertext; it has zero ability to decrypt
This is a practical, auditable implementation of the "zero-knowledge" file sharing pattern

Why it might fit here:

It's a clean real-world reference for WebCrypto API usage
The source code is MIT licensed and auditable: https://github.com/FileShot/FileShotZKE
Live: https://fileshot.io

Could sit alongside other applied crypto tools or real-world WebCrypto examples.
