MD5_RSA

des经典加密算法，实现数据交互过程中的保密(des classical encryption algorithm, data confidentiality during the interaction)

整体思路 用createkey.java 文件来产生秘钥，用jiami.java 文件来实 现加密，用jiemi.java 文件来实现解密,用BigInteger.java 来实现 大数的表示及运算，用rsa.java 来实现前端图形界面显示。有关函 数见五个文件里的具体实现。 (The overall outlook createkey.java document used to generate secret keys, used to achieve jiami.java file encryption, used to achieve jiemi.java documents declassified by BigInteger.java to achieve expression of large numbers and calculations, using rsa.java to achieve front-end graphical interface display. Related functions, see the five concrete realization of the document.)

MD5加密算法，可以加密包含二进制数据的数据块，生成16字节MD5加密数据。(MD5 encryption algorithm to encrypt data blocks that contain binary data, generates a 16-byte MD5 encrypted data.)

C++ implementaion for RSA together with the Wiener attack. It uses NTL library for big numbers

说明：  混合加密系统，支持多种加密方式混合加密系统，支持多种加密方式(Hybrid encryption system)

VB文件加密器（异或加密）,有需要的就下载吧。(VB file encryption (XOR encryption), there is a need to download it.)

VC++下MD5运行和使用示例,可以正常使用MD5算法(VC MD5)

壳代码，对于学习壳编写的同学具有一定的参考价值，绝对经典(Shell code, written for students to learn the shell has a certain reference value, an absolute classic)

自己动手写加壳程序，按照文档一步一步来，做你自己的加壳程序！(Packers to write himself, according to the document step by step, do your own packers!)

一个用vc编写的aes算法实现，含有128，192，256三种钥匙长度的(a prepared using vc Orangk'aes algorithm, containing 128,192,256 length of the three key)
