推荐答案

可能，你会发现它很难：

1）JPG是一种有损压缩算法，它会抛弃眼睛无法看到的数据 - 所以如果你试图隐藏一个在其中，原始数据恢复良好的可能性一点也不好 - 或者隐藏数据将立即显而易见......

2）EXE文件通常非常大：图像文件通常很小。把一些大东西藏在一个小东西里就像试图把一个谢尔曼水箱隐藏在厨房橱柜里 - 人们一定会注意到橱柜的尺寸比你想象的大6米......



但这是你的问题，不是我的...而且一个非常简单的谷歌会找到你这个：http://www.dreamincode.net/forums/topic/27950-steganography/ [ ^ ] - 它帮了我。

Probably, you're going to find it hard:
1) JPG is a lossy compression algorithm, which "throws away" data the the eye "can't see" - so if you try to hide an exe in it, the chances of a good recovery of the original data are not good at all - or the "hidden" data will be immediately obvious...
2) EXE files are generally quite large: image files are generally quite small. Hiding something large in something small is rather like trying to hide a Sherman tank in a kitchen cupboard - people are bound to notice the cupboard is 6 metres bigger in all dimensions than you would expect...

But it's you problem, not mine... And a very simple Google would have found you this: http://www.dreamincode.net/forums/topic/27950-steganography/[^] - it did me.
