我应该提供什么“消化”论据？

我以前在login和注册function中有以下代码：

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 model.UserSchema.methods.validPassword (/opt/myapp/models/Users.js:35:23) at /opt/myapp/config/passport.js:16:23 at model.Query.<anonymous> (/opt/myapp/node_modules/mongoose/lib/model.js:3745:16) at /opt/myapp/node_modules/kareem/index.js:277:21 at /opt/myapp/node_modules/kareem/index.js:131:16 at _combinedTickCallback (internal/process/next_tick.js:131:7) at process._tickCallback (internal/process/next_tick.js:180:9) 

那么有没有人知道我应该提供给crypto.pbkdf2Sync digest参数？ 我希望注册用户/密码仍然有效。

Answer 1

从crypto.pbkdf2Sync 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algorithmsha512这是digest parameter请参阅文档中的最后一个参数。
