FileShot.io – open-source AES-256-GCM zero-knowledge file encryption in the browser #240
Description
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.
