node.js - TypeError : crypto__WEBPACK_IMPORTED_MODULE_5__. generateKeyPairSync 不是函数

Question

我安装了 Node.js v12.13.0，但仍然出现以下错误。我已经检查了很多关于此的问题，但所有问题的解决方案都是更新的 Node 版本。

Uncaught TypeError: crypto__WEBPACK_IMPORTED_MODULE_5__.generateKeyPairSync is not a function

从堆栈跟踪来看，这段代码似乎正在浏览器中运行。 crypto.generateKeyPairSync API 仅在 Node.js 中可用。基本上，它只能在服务器端使用，不能在前端使用。
你需要类似 Web Crypto API 的东西，内置于现代浏览器中。 Here is an example RSA key pair generation:

let keyPair = window.crypto.subtle.generateKey(
  {
    name: "RSA-OAEP",
    modulusLength: 4096,
    publicExponent: new Uint8Array([1, 0, 1]),
    hash: "SHA-256"
  },
  true,
  ["encrypt", "decrypt"]
);
