解密加密文件并在Java中执行 [英] Decrypting an encrypted file and executing in Java

问题描述

我目前正在一个可以对文件进行加密和解密的项目。我正在用Java开发它。

这是它的工作原理（简化）：

1. 首先，我读取文件并将其转换为字节数组


2. 然后我加密字节数组并将其写回文件

当我想要运行加密文件时，我做的相反，就像这样：

1. 我读取加密文件并将其转换为字节数组


2. 然后我解密字节数组并将其写回文件。

所以文件被转换回原来的形式。

我的问题是，我不想将解密的字节数组作为文件写入磁盘。

通过运行它，我的意思是执行它，因为它是一个Win32可执行命令。

提前感谢

解决方案

我会说你的选择在这里是有限的，因为你依赖Windows开始这个过程。 Java是跨平台的，可能无法以您想要的方式挂接到Windows中。

在纯Java领域之外，您可以创建一个ramdisk，并将EXE写入Ramdisk，或者跨桥到.NET，如这个答案（和答案内的问题链接）。

I am currently working on a project where i can encrypt and decrypt files. I am developing it in Java.

This is how it works (simplified):

1. First I read the file and convert it to a byte array
2. Then I encrypt the byte array and write it back to a file

When I want to run the encrypted file, I do the opposite, so like this:

1. I read encrypted file and convert it to byte array
2. Then I decrypt the byte array and write it back to a file.

So the file is converted back to its original form.

My problem is, I do not want to write the decrypted byte array as a file to the disk.

Is there a way to do this? I want to run the decrypted byte array directly in memory. By "running" it, I mean executing it, because it is a Win32 executable crypter.

Thanks in advance, Onur

解决方案

I'd say that your options are limited here, because you are dependent on Windows starting the process. Java, being cross-platform, probably doesn't have the ability to hook into Windows in the way you want.

Straying outside the realms of pure Java, you could create a ramdisk and write the EXE to the Ramdisk, or perhaps bridge across to .NET, as described in this answer (and question links inside that answer).
