如何实现IDEA？ [英] How to implement IDEA?

问题描述

我必须创建一个应用程序，它可以使用IDEA（国际数据加密算法）在Java或C＃中加密和解密文本文件。我知道在Java有内置的JCE（Java加密扩展），但如何进一步，任何人都可以给我一些建议吗？

I have to make an application which can encrypt and decrypt text file using IDEA(International Data Encryption Algorithm) in java or C#. I know that in java there is inbuilt JCE(Java Cryptography Extension) but how to proceed further, will anybody please give me some suggestions?

谢谢。

推荐答案

您可以尝试使用 BouncyCastle ，可用于Java和C＃。但是，根据此注意，您需要获得适合IDEA支持的正确jars（假设Java） / a>：

You could try to use BouncyCastle, which is available for Java and C#. However, you'll need to get the right jars (assuming Java) for IDEA support, according to this note:

从版本1.40开始，IDEA加密算法的实现
从常规jar中删除
文件在
请求的一些用户。具有格式 -ext - 仍然
的Jars
包括IDEA实现。

From release 1.40 the implementation of the IDEA encryption algorithm was removed from the regular jar files at the request of a number of users. Jars with names of the form -ext- still include the IDEA implementation.

EDIT （添加指针示例）：
我没有尝试，但我认为 DESExample 可以通过替换 DESedeEngine 与am IDEAEngine （类似于其他类）。

EDIT (added pointer to example): I haven't tried, but I think that the DESExample could be adapted to do what you want, probably by replacing the DESedeEngine with am IDEAEngine (and similar for other classes).
