Crypto in Expo app?

🐛 Bug Report

Hi,

I’m using crypto-js to handle AES encryption in my Expo app. Not sensitive data, but still, better be safe than sorry. Recently, I noticed that crypto-js, which was working fine, stopped working since (I guess) I upgrade to Expo 37, throwing this error:

The package at "node_modules/crypto-js/core.js" attempted to import the Node standard library module "crypto". It failed because React Native does not include the Node standard library. Read more at https://docs.expo.io/versions/latest/introduction/faq/#can-i-use-nodejs-packages-with-expo
Failed building JavaScript bundle.

Any idea how I can keep using an AES encryption in Expo?
