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.
