DES

DES加密的MFC实现,主要包括两部分组成，有字符串加密和文件加密两种模式，实现了3DES功能，让加密更安全(including string and files by DES)

VB6.0调用Windows系统的API计算MD5码。这个代码跟网上流行的代码相比，具有代码简洁，维护方便，运行效率高等优点。运行速度比用纯VB6实现的快得多。(VB6.0- Call Windows system API calculate MD5 code. This code is compared with the popular online code, with code simple, easy maintenance, high efficiency. Runs faster than pure VB6 realize faster.)

RSA加密算法的C预言实现，对一张灰度图进行加密，然后再解密(RSA encryption algorithm in C prophecy fulfilled, encrypt and then decrypt a grayscale)

基于LSB的信息隐藏技术——MFC——编译已经通过运行正常(LSB-based Information Hiding- MFC- has been compiled by running the normal)

一个袖珍的vc++加密软件，同时还可以解密，加密文件的范围挺大的，几乎所有文件都可以加密，输入密码并解密，好像不是真正意义的加密，只不过是用文件额外加密的方法进行加密，较早时候的程序，不过编译还是顺利的。 (A pocket-sized vc++ encryption software, but also can decrypt encrypted files the scope of getting bigger, almost all the files can be encrypted, enter the password and decrypt the encryption does not seem real, but the file is an additional method of encryption to encrypt Earlier procedures, but the compiler is still smooth.)

说明：  六种加密算法源码，包括CRC32校验，DES加密，MD5，rsa数字签名，RSA演示，简单加密(Six encryption algorithm source code, including the CRC32 checksum, DES encryption, MD5, rsa digital signature, RSA presentation, simple encryption)

DES加密方法加密BMP图像，CBC方式实现。(DES encryption methods encryption BMP image, CBC way.)

AES加解密C语言源代码，可直接运行通过，方便大家借鉴学习(AES encryption and decryption of C language source code, can be directly run by, we facilitate learning from)

一种加密算法,可以直接对密文进行操作，而不需要知道相应的明文。(homomorphic encryption)

加密算法RSA，DSA等，用C++实现，内附加有详细的说明(Encryption algorithm RSA, DSA, etc., using C++ Realize, with additional detail has)
