修改ZipFile类以将编码文件用作zip文件

The idea is to encrypt a jar file, actually to encode it inorder to make it impossible to open with zip utility software (eg: winzip, winrar or ...).

这个想法是加密一个jar文件,实际上是为了编码它,以便无法用zip实用软件打开它(例如:winzip,winrar或......)。

For encoding the jar file, i have just increment every byte of jar file for test purpose. then i want to read the encoded jar file as ZipFile to work with its data like a real jar file.

为了编码jar文件,我只是增加了jar文件的每个字节以供测试。然后我想读取编码的jar文件作为ZipFile来处理它的数据,如真正的jar文件。

Now the problems is that when i initialize a ZipFile, it needs an reference of file, which the ZipFile class always consider that the file is a Zip file; but actually it is not.

现在的问题是,当我初始化ZipFile时,它需要一个文件的引用,ZipFile类总是认为该文件是一个Zip文件;但实际上并非如此。

i want to change the read(...) method of ZipFile or any other method that deals with the input stream, to perform the decoding while reading the data from stream.

我想更改ZipFile的read(...)方法或任何其他处理输入流的方法,以便在从流中读取数据时执行解码。

if any body can help with this solution or have any suggestion please tell me.

如果有任何机构可以帮助解决这个问题或有任何建议请告诉我。

you could use the stream version of ZipFile, ZipInpuStream. it does not care the stream you supplied is modified or not.

你可以使用ZipFile的流版本,ZipInpuStream。它并不关心您提供的流是否被修改。
