Question

我曾经在登录和注册功能中使用以下代码：

var crypto = require('crypto');
... ...
this.hash = crypto.pbkdf2Sync(password, this.salt, 1000, 64).toString('hex');

我已经注册了用户。

昨天，我更新了npm，现在显示错误：

events.js:182
      throw er; // Unhandled 'error' event
      ^

TypeError: The "digest" argument is required and must not be undefined
    at pbkdf2 (crypto.js:635:11)
    at Object.exports.pbkdf2Sync (crypto.js:628:10)

    at _combinedTickCallback (internal/process/next_tick.js:131:7)
    at process._tickCallback (internal/process/next_tick.js:180:9)

所以有人知道我应该向digest提供crypto.pbkdf2Sync论证吗？我希望注册用户/密码仍然有效。

来自crypto.pbkdf2Sync的node.js文档：

const crypto = require('crypto');
const key = crypto.pbkdf2Sync('secret', 'salt', 100000, 512, 'sha512');
console.log(key.toString('hex'));  // '3745e48...aa39b34'

您还需要指定编码算法sha512这是digest parameter，请参阅文档中的最后一个参数。

我应该提供什么“消化”论点？
