node-expo-crypto

The package node-expo-crypto provides the same interface of expo-crypto. So Thus, you can implement mocks that work as expected even in the Node environment.

const crypto = require('node-expo-crypto');

const digest = await crypto.digestStringAsync('sha256', 'hello');
console.log(digest); // 2cf24dba5fb0a30e26e83b2ac5b9e29e1b161e5c1fa7425e73043362938b9824

This package also contains default mocks for Jest testing framework. For details on how to configure, see below.
