推荐答案

Crypto是一个节点js模块，运行React Native时-它使用Javascript Core。加密不包括在其中。当我安装crypto时，我使用了以下软件包：

Crypto is a node js module, when React Native is run - it uses Javascript Core. Crypto isn't include within this. When I installed crypto I used the following package:

https://www.npmjs.com/package/react-native-crypto

说明：

npm i --save react-native-crypto
# install peer deps 
npm i --save react-native-randombytes
react-native link react-native-randombytes
# install latest rn-nodeify 
npm i --save-dev tradle/rn-nodeify
# install node core shims and recursively hack package.json files 
# in ./node_modules to add/update the "browser"/"react-native" field with relevant mappings 
./node_modules/.bin/rn-nodeify --hack --install
rn-nodeify will create a shim.js in the project root directory
// index.ios.js or index.android.js
// make sure you use `import` and not require!  
import './shim.js'
// ...the rest of your code

在您的index.js文件中导入 shim.js 。

Import shim.js in your index.js file.

完成加密后应该可以使用，如果仍然无法使用，则必须在App.js文件中创建一个const，如下所示：

When you have done that crypto should be made available, if it still doesn't work I had to create a const in my App.js file like so:

export const cryp = require('crypto');

并将其导入所需的组件中。

And import it into the components you need.

更新

我为此做了一个全新的构建，如下：

I've done a fresh build for this, I followed the below:

本机初始化TestApp

按照以上有关加密的说明进行操作。

Follow the instructions above for Crypto.
