一个自动条形码打印程序-an automatic barcode printing program

参考了电脑爱好者2000第10期的一篇关于将文件隐藏于位图中的文章，本程序还有许多可以改进的地方，例如可以加入CRC校验，加密,多线程等内容。-reference to the 2000 resolution computer enthusiasts 10 of a document on Bitmap hidden in the article, there are many procedures can be improved, for example, can join the CRC, encryption, such as multithreading.

对所需要保密的文件进行加密，代码简洁易懂。-right by the need for confidentiality of documents encrypted code easy to read.

把信息隐藏到图片中，比加密更安全-hidden message to the pictures, more secure encryption

DES(Data Encrypton Standard) 算法的实现网上已经有很多，本人在此讲述的是在DES算法加密过程中如何查看16迭代过程中生成的Ki,Li,Ri,Fi,Si等，这样可以当做一个DES加密对照器，这样可以方便的发现你在加密过程中出现的错误! -DES (Data Encrypton Standard) algorithm has been achieved online many, I would like to speak on is the DES encryption algorithm to see how the process 16 iterative process of generating Ki, Li, Ri, Fi, Si, etc., can serve as a control device DES encryption, this can easily find you in the process of encryption the mistakes!
