这是一个获取ACCESS 数据库密码的强悍软件, 适用于ACCESS2-This a password access to the Access database software intrepid apply to ACCESS2

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 ~ ~ ~ ~

对于简单的由单一的线性移位寄存器，获得一串01比特序列，通过BM算法可以得到生成此01比特串的最小线性多项式（在二元域上）。

从一个随机文件读取256字节数据形成数据区DArea，再应用洗牌法所给的方法生成0~255的一个全排列DTab。试分别写出"求DArea中全部数据经 （1）以DTab为S-盒； （2）以DTab为P置换 -from a random file read 256 byte data area DArea form data, re-shuffling in law application to the formation of 0 ~ 255 DTab a full array. Try to write were "seeking DArea by which all data (1) DTab S-boxes; (2) DTab replacement for the P

本文介绍了在JAVA开发环境中如何对文件和数据进行有效的加密，特别是里面API的调用-This paper presents the Java development environment and how to document effective data encryption, in particular inside the API ca
