VC++实验QQ加密相册查看器,输入QQ号即显示相片,源码宝贵,请速下载:-)(VC experimental QQ encryption album viewer, the importation of QQ, which indicates that the photographs, source of valuable information to offer is urged to download :-))

今天我们学习了des对称加密算法这是一个des算法的C++实现(This is a des !)

基于vc++的音频加密软件的设计通过查阅资料对当今比较广泛使用的音频加密算法进行选择，并对其中的三种算法进行其性能方面的比较，找出其中加密性能较好(Audio encryption software design based on VC++through access to information is widely used for today s audio encryption algorithm to choose, and the three kinds of algorithms are compared, and its performance to find out one encryption)

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.)

以C++语言在微机上实现了美国数据加密标准DES。可随微机软盘任意路径下的任何文件，加密，加密文件可在软、硬盘任何目录下或在网络中传送；另一方面可对软、硬盘中的任何文件进行解密，解密后的文件除在末尾多出几个空格符外与原文件完全相同，绝不影响EXE文件，COM文件或数据库文件的使用。密钥有加密者在键盘输入8个字符。(In c++ language microcomputer to U.S. data encryption standard DES. With the computer floppy disk arbitrary path of any of the files, encryption, encrypt files can be in soft, hard disk any directory or in the network transmission On the other hand, soft, hard disk to the any classify documents, the decrypted file in the end in a few more the space appears with the original documents are all the same, never affect EXE file, COM file or database files use. Key there are JiaMiZhe in keyboard input 8 characters. )

椭圆曲线加密算法，设置服务器一步的源代码(elliptic curve encryption algorithm, the step to set up the server source code)

在实现AES基础上，用C编写CMAC算法并调试通过。输入数据进行CMAC验证。(In the realization of AES based on the CMAC algorithm written in C and debugging. CMAC input data validation)

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)

实现对单文件的DES加密解密，不限制大小，DES加密部分自写，非调用，用于学习DES原理。(The realization of the single document DES encryption and decryption, no limit to the size, DES encryption part self written, non call, for learning DES principle.)
