Encryption

Themida的另类破解 附件提供的一个程序是用汇编写的PE信息小工具，用Themida1855加密，加密选择RISC-64 processor，全选加密可选项，并对部分API函数使用VM加密，入口虚拟系数选择15。

用于加密vbs和bat代码,可用于保护自身的资料和代码发送给别人试用，防止被盗取劳动果实，并且附加解密文件，以免原文件丢失代码遗失(Used to encrypt VBS and bat code, can be used to protect their own data and code sent to others for trial, to prevent the stolen fruits of labor, and add decrypted files, so as to avoid losing the original file code.)

说明：  RSA算法matlab实现,说明：由于能力有限，我并没有编写产生大素数的程序，在实验时就采用手动的写如两个不同的较小的素数。(RSA algorithm matlab implementation, note: Due to limited capacity, I do not have a large prime numbers prepared by the procedure, in the experiments on the use of manual writing, such as two different smaller prime number.)

用Visual c++实现数字图像迭代混沌加密-Using Visual c++ Realize digital image iterative chaotic encryption

说明：des算法的实现代码 */ 能够实现56位或56*n密钥的des算法，可以通过该程序提供的接 进行数据的加密，保证数据在传送过程的安全性-Description: des algorithm realize the code*/can be achieved 56 or 56* n keys des algorithm, can be provided through the program access data encryption to ensure data security during transmission of

RSA加密算法，实现对文字的加密，将文字转化成数字后用RSA原理进行加密(This is RSA encryption algorithm)

创建一个经过加密的软件系统信息文件，在软件启动时会校验这些信息，判断是授权用户在使用该软件。-create an encrypted document information system software, the software will start checking the information, and judgment is authorized users in the use of the software.

说明：  可视密码实现，生成4个密钥图片，任意两个叠加会生成明文(visual cryptographic implementation, generating four key pictures, any two superposition will generate plaintext)

一种比较简单的加密方法，存成Form1.frm,就可以打开了(This is a simple encryption algorithm)
