FileEncrypt

md5算法,采用c++实现的md5_16位实现-md5 algorithm, used to achieve the c-achieving md5_16

用于加密图像和解密图像，可以实现图像的简单加密解密，界面友好(Used to encrypt the image and the decrypted image, you can achieve the image of a simple encryption decryption, the friendly interface)

Des VB类库-Des VB Class

自己写的一份RSA算法。可正常执行。控制台程序。(Write your own copy of the RSA algorithm. Can be performed normally. Console program.)

本文件实现的是对水印的加密及解密，有3种方式，猫脸变换，混沌置乱和zigzag置乱。(The file contains sseveral functions, which can encrypt and decrypt the watermark,including Arnold Transform,chaotic and zigzag. )

一个周期3的多表代替密码，第1个表由密钥字法产生（密钥字自拟），第2个表由洗牌法产生（注意，字母a~z与数字0~25一一对应），第三个表由公式法产生（数学公式自拟，注意它须是Z26上的一个一一变换）(a cycle of three multi-table instead of passwords, a table by key word method, (key word from the intended), Table No. 2 produced by shuffling method (note, a letter with a number of z ~ 0 ~ 25 he gathers), 3rd tables generated by the formula (from the proposed mathematical formula, it should pay attention to the Z26 is a transformation on January 1))

说明：  一种64位的DES加密代码，可以使用挂在APB上(dec enc key to 64 bit rate)

说明：  能够用MATLAB实现DES算法加密，包含密钥生成和S盒的生成函数(DES algorithm can be encrypted with MATLAB, including key generation and S-box generation function.)
