我应该提供什么“摘要”论点？

Question

我以前在登录和注册功能中有如下代码：

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

而且我已经注册了用户。

昨天更新了npm，现在报错：

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)

那么有人知道我应该向crypto.pbkdf2Sync 提供什么digest 参数吗？我希望注册的用户/密码仍然有效。

Answer 1

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。
