可靠的实现PBKDF2-HMAC-SHA256为JAVA [英] Reliable implementation of PBKDF2-HMAC-SHA256 for JAVA

问题描述

对于JAVA，有没有可靠的PBKDF2-HMAC-SHA256实现？

Is there any reliable implementation of PBKDF2-HMAC-SHA256 for JAVA?

我曾经用bouncycastle加密，但是没有提供PBKDF2WithHmacSHA256'。

I used to encrypting by bouncycastle but it does not provides PBKDF2WithHmacSHA256'.

我不想自己写加密模块。

I do not want to write crypto module by myself.

你可以推荐任何替代库或算法with bouncycastle）

Could you recommend any alternative library or algorithm (if i can stick with bouncycastle)

（这里是bouncycastle支持算法的算法）
http://www.bouncycastle.org/specifications.html

(here are algorithms that bouncycastle supports algorithm) http://www.bouncycastle.org/specifications.html

推荐答案

使用BouncyCastle类：

Using BouncyCastle classes directly:

PKCS5S2ParametersGenerator gen = new PKCS5S2ParametersGenerator(new SHA256Digest());
gen.init("password".getBytes("UTF-8"), "salt".getBytes(), 4096);
byte[] dk = ((KeyParameter) gen.generateDerivedParameters(256)).getKey();
