Javascript cryptography in the wild (github.com)

in my messaging app, javascript cryptography is the backbone of security so its important for it to be reliable. i would like to introduce you to my decentralized chat app:

https://github.com/positive-intentions/chat

i created thin wrapper around browser-based cryptography functions provided by the browser. it is using webpack 5 module federation to import it at runtime.

https://github.com/positive-intentions/cryptography/blob/staging/src/stories/components/Cryptography.tsx

with this i think i can effectively create encrypted p2p, which i hope to be a step towards true security (but it will take a while to get there).

(note: my app is an experimental unstable proof-of-concept. it is provided for demo and testing purposes.)

Bookmarked and will revisit when work isn’t so crazy. Looks interesting!

I've wanted to do that for years! Good job on actually doing it :)
