Do you need the Expo plugin for this library to work with Expo?

Question is in the title but I tested it and it seems like you don't need the expo plugin in the app plugin's config but just wanted to double check?

Also, the installation instructions are a bit confusing for Expo. Do you also need to install react-native-quick-base64 and react-native-nitro-modules for Expo apps? I did just in case but its a bit unclear.

Yeah, installing both was the right call. nitro-modules and quick-base64 are real peerDependencies (nitro >=0.31.2, quick-base64 >=3.0.0) with no optional flag, so the lib won't work without them. npm 7+ auto-pulls them on a fresh npm install, but that's not guaranteed: with --legacy-peer-deps nitro-modules didn't get installed for me, so listing all three explicitly like the RN snippet does is the safe move.

The expo plugin is the part you can skip for basic crypto. expo and expo-build-properties are marked optional in peerDependenciesMeta, and the config plugin (app.plugin.js) only does two things: an Xcode 16.x build workaround, and enabling libsodium when you pass sodiumEnabled. So you don't need it in your app.json plugins unless you hit those iOS build issues or want the sodium algorithms.
