Node.js provides an implementation of the standard Web Crypto API.Node.js提供了标准Web Crypto API的实现。

Use require('node:crypto').webcrypto to access this module.使用require('node:crypto').webcrypto访问此模块。

const { subtle } = require('node:crypto').webcrypto;

(async function() {

  const key = await subtle.generateKey({
    name: 'HMAC',
    hash: 'SHA-256',
    length: 256
  }, true, ['sign', 'verify']);

  const enc = new TextEncoder();
  const message = enc.encode('I love cupcakes');

  const digest = await subtle.sign({
    name: 'HMAC'
  }, key, message);

})();
