tweetnacl 在 React Native 中不返回 PRNG 错误

Question

我在 React Native 中使用 nacl

我只是在下面写下代码。

它在 randombytes 变量中不返回 PRNG 错误。

  const test = nacl.box.keyPair();

这也是我的 package.json 。

  "dependencies": {
    "@react-navigation/material-bottom-tabs": "^6.2.15",
    "@react-navigation/native": "^6.1.6",

我以前也遇到过同样的问题。在研究过程中我发现内部nacl使用nacl.randomBytes()。但是，实际实现会根据您使用的平台而有所不同。因为node它调用了crypto.randomBytes()ReactNative 环境中未定义的 。

要使用naclReactNative，您需要自己提供定义。您可以通过安装react-native-get-random-values软件包并添加

import 'react-native-get-random-values'

到index.js

这将提供nacl的定义crypto.randomBytes()。
