问题描述

I noticed that there are two bouncycastle provider libraries for Java; bcprov and bcprov-ext. How do they differ? How do I choose which to use?

推荐答案

bcprov 通常是您想要的库。

bcprov-ext 包含一些晦涩的加密算法，自v1.4.0以来就不再是主要版本的一部分。

bcprov-ext includes some obscure crypto algorithms that haven't been part of the main release since v1.4.0.

这在最新发布页面中进行了简要说明：

This is briefly explained on the latest releases page:

从1.40版开始，应许多用户的要求，从常规jar文件中删除了一些加密算法的实现。名称形式为 *-ext-* 的罐子仍包含这些罐子（当前列表为：NTRU）。

From release 1.40 some implementations of encryption algorithms were removed from the regular jar files at the request of a number of users. Jars with names of the form *-ext-* still include these (at the moment the list is: NTRU).

NTRU似乎是此算法。就我个人而言，我以前从未听说过它。

NTRU seems to be this algorithm. Personally I'd never heard of it before...
