#webcryptoapi — Public Fediverse posts

Local-Only File Encryption with JavaScript.

I've been exploring the #WebCryptoAPI and I'm impressed!

When combined with the #FileSystemAPI, it offers a seemingly secure way to #encrypt and #store files directly on your device. Think #localstorage, but with #encryption!

I know #webapps can have #security vulnerabilities since the code is served over the web, so I've #OpenSourced my demo! You can check it out, and it should even work if #selfhosted on #GitHubPages.

* This is NOT a product. It's for #testing and #demonstration purposes only.
* It has NOT been reviewed or audited. Do NOT use for sensitive data.
* The password encryption currently uses a hardcoded password. This is for demonstration, not security.
* This is NOT meant to replace robust solutions like #VeraCrypt. It's just a #proofofconcept to show what's possible with #browser #APIs.

I’m working towards something for #secure / #private / #simple #P2P #filetransfer. It isnt as “simple” as it could be, im still working on it, but ive got it down to:

Zero-installation as a #PWA

Zero-registration by using local-only storage

#P2P-authentication using #WebCryptoAPI

Fast #datatransfer using #WebRTC, #syncthing, #croc, #sphynctershare and countless others. the key difference in my approach is that its a #webapp thats ready to go without any "real" setup process. you just need a browser.

I’m aware there are things like #SFTP and several other established protocols and tools. I started doing this because I was learning about #WebRTC and it seems suprisingly capable. This isnt ready to replace any existing apps or services.

(Note: I know you guys are typically interested in #opensource code. this project is a spin-off from a bigger project: https://github.com/positive-intentions/chat)

Let me know what you think about the app, features and experience you would expect from a tool like this.

SUPER IMPORTANT NOTES TO PREVENT MISLEADING:

These projects are not ready to replace any existing apps or services.

These projects are not peer-reviewed or security audited.

The chat-app is #opensource for transparency (as linked above)... but the file-app is not open souce at all (especially spicy when not reviewed or audited.).

All projects behind positive-intentions are provided for testing and demo purposes only.

Native support for ed25519/x25519 in the browser would be a huge step forward for in-browser/client-side cryptography.

Looks like Google is holding up our ability to use it in production.

(Firefox and Safari both have support enabled by default.)
