expo-standard-web-crypto
Advanced tools
A partial implementation of the W3C Crypto API for Expo
This package provides a partial polyfill of the W3C Crypto API for Expo. Namely, Crypto#getRandomValues() is implemented. See the W3C Crypto specification for the API documentation.
First follow the instructions for installing expo-crypto, which is required by this package. Then install this package.
npm install expo-standard-web-crypto
There are two ways to use this package: you can import a Crypto instance or you can globally define crypto. Some code may expect the latter.
Importing a Crypto instance:
import crypto from 'expo-standard-web-crypto';
Globally defining crypto:
import { polyfillWebCrypto } from 'expo-standard-web-crypto';
polyfillWebCrypto();
// crypto is now globally defined
In either case, if your runtime environment already defines crypto globally, this package uses that instance instead of providing its own.
Contributions are very welcome! Please refer to guidelines described in the contributing guide.
