Is there any plans to add WebCrypto API to React-Native?

[pedrouid]

A lot of quick hacks and libraries try to either polyfill or build their own solutions for crypto but browsers already have a good library that is super performant for cryptography.

Is there any plans to add WebCrypto API to the React-Native environment?

[pedrouid]

The most used and supported library currently is react-native-crypto but it requires rn-nodeify which is not an ideal solution and it feels like it should be built-in into react-native.

However if it was I think the API shouldn't use the NodeJS Crypto module API but the WebCrypto API which is supported by all major browsers. In my view, the react-native environment should aim to match the browser environment as much as possible and I think this would be a great addition

I am not sure if it makes sense to make this a part of Web Core. Why not have a "recommended" community support library for Web Crypto ?

[pedrouid]

Why not? Most APIs that are available on browsers are supported or provide alternatives. Fetch API is available. LocalStorage API is available as AsyncStorage. How is WebCrypto API different?

I personally would like having WebCrypto added, even though I can see the benefit of having it in a separate module as well...

Deno is also in the process of adding it, and I really like the idea of many JavaScript runtimes that are compatible with each other.

I started working on react-native-webcrypto but it only supports Android currently...

edit: I also implemented getRandomValues() here, it's stable for both iOS and Android 🎉

I agree with @TheSavior and @axemclion that our current focus is to reduce the surface area instead of adding to it. @LinusU I would recommend you to build out your third-party dependency as you are doing now. Maybe eventually we could move it to react-native-community, and officially recommend it in the documentation for people who would like to use this feature.
