md5算法，实现给一个512bir数据块加密，程序有详细的注释，

文件加密技术一例给文件加密的技术很多,其中又分为不同等级,以适合不同场合的需要.这里给出最简单的文件加密技术,即采用文件逐字节与密码异或方式对 文件进行加密,当解密时,只需再运行一遍加密程序即可.-file encryption technology to the case file encryption technologies lot, which will be divided into different levels, to suit the needs of different occasions. Here is the most simple file encryption technology, which adopts a case-by-byte file with the password or different ways to document encryption, decryption, only re-running again encryption procedures.

组播密钥的批次更新算法，基于LKH的单次密钥更新方案和Batch Rekeying方案的原理、结构和密钥更新过程等。并着重对 Batch Rekeying 方案的性能与单次密钥更新方案作了简单的比较。 通过比较和分析得到结论:定时更新的Batch Rekeying 方案在更新开销上比单次更新更有优势 -Multicast key batch update algorithm, Based on the LKH single Rekeying program and the program Batch Rekeying principle, Rekeying structure and processes. And Batch Rekeying focused on the performance of the program with a single Rekeying program with a simple comparison. By comparing and analyzing conclusions : regularly updated Batch Rekeying program in the updated overhead than a single update more advantages

是当今比较新的算法MD5，比DES和DES5都要加密好，是dll文件，在自己写的程序中加入它，就可以直接用了，全是意接口的形式-Is the relatively new algorithm MD5, should DES5 than DES and encryption, and is a dll file, written in their own process to join it, can be directly used, the interface is intended to form ~ ~ ~ ~

RSA的加密算法的应用DEMO 也是用来加密的。-RSA encryption algorithm application DEMO also is uses for to encrypt.

本次实现采用流水线结构，分析子密钥与原始密钥的直接关系，利用组合逻辑同时产生16个子密钥，总体上既兼顾了效率，又不占用太多资源，经仿真测试，完全通过。

汇编程序写的Hash校检程序，分享源码，支持SHA1和MD5两种，支持拉拽，支持剪切板的复制和比对，有进行条，自动计算耗时 （使用了不太精确的计时器），速度还是可以的，大概就这样。
