Java等效于C＃的Rfc2898DerivedBytes [英] Java equivalent of C#'s Rfc2898DerivedBytes

问题描述

我想知道有没有人试图做一个相当于

$ pre> Rfc2898DeriveBytes key = new Rfc2898DeriveBytes（secret，saltValueBytes）;
byte [] secretKey = key.GetBytes（16）; Java中的


秘密是一个字符串（密码），而saltValueBytes是一个字节数组的盐。

我尝试过的东西，但似乎不能包装我的

解决方案

我发现这个实现通过Google搜索，但我从来没有使用过。

RFC 2898的免费Java实现
/ PKCS＃5 PBKDF2

似乎没有小而自由的
可用的Java实现RFC
2898 / PKCS＃5可用。小的

给定HMACSHA1在

我的代码是一个洁净室实现

I was wondering if anyone have tried to do an equivalent of

Rfc2898DeriveBytes key = new Rfc2898DeriveBytes(secret, saltValueBytes);
byte[] secretKey = key.GetBytes(16);

in Java. Where secret is a string(password), and saltValueBytes is, well, a salt in byte array.

I've tried stuff, but can't seem to wrap my head around it.

解决方案

I found this implementation by means of a Google search but I have never used it.

A free Java implementation of RFC 2898 / PKCS#5 PBKDF2

There seems to be no small and freely available Java implementation of RFC 2898 / PKCS#5 available. Small as in only a few source files, with trivial compile and no dependencies, free as in LGPL.

Given the availability of HMacSHA1 in the standard SUN JCE cryptographic provider, such an implementation is quite simple and can be derived from the RFC description quite literally. My code is a clean-room implementation with only the RFC as its basis.
