关于java：由crypto.pbkdf2对象创建的解密密码

Decrypt Password Created by crypto.pbkdf2 Object

我在javascript上运行以下代码，在NodeJ上运行：

encryptPassword: function(password) {
if (!password || !this.salt) return '';
var salt=new Buffer(this.salt, 'base64');
return crypto.pbkdf2Sync(password, salt, 10000, 64).toString('base64');
}

如何实现解密功能？
它可以是Java或javascript。

谢谢！

PBKDF2是一种单向哈希算法。无法解密生成的哈希。您可以在此处了解更多信息。

A one way hash performs a bunch of mathematical operations that
transform input into a (mostly) unique output, called a digest.
Because these operations are one way, you cannot ‘decrypt’ the output-
you can’t turn a digest into the original input.

如果要使用PBKDF2来存储和比较密码，您可能会对pbkdf2库感兴趣。它使密码的生成和比较容易：

var pbkdf2 = require('pbkdf2');
var p = 'password';
var s = pbkdf2.generateSaltSync(32);
var pwd = pbkdf2.hashSync(p, s, 1, 20, 'sha256');
var bool = pbkdf2.compareSync(pwd, p, s, 1, 20, 'sha256');
