LZ77压缩/解压缩算法

设f(x)=1+x+x2+x5+x27，试分别写出实现下列移位寄存器的程序： 以f(x)为联接多项式的DSR； 以f(x)为联接多项式的LFSR。 可供选择的联接多项式： f1(x)=1+x+x4+x6+x30； f2(x)=1+ x3+ x31； f3(x)=1+ x6+ x31； f4(x)=1+ x7+ x31； f5(x)=1+ x13+ x31； -Let f (x) = 1 x x2 x5 x27, respectively try to write the following Shift Register : f (x) connected to the DSR polynomial; f (x) for connectivity polynomial LFSR. Connection options polynomial : f (x) = 1 x x4 x6 x30; F2 (x) = 1 x3 x31; f3 (x) = 1 x6 x31; f4 (x) = 1 x11 x31; f5 (x) = 1 x13 x31;

大名鼎鼎的DES加密算法，内有html文档做出详细解释-famous DES encryption algorithm, which is html files provide a detailed explanation

文件加密方法，非常简洁重要的代码 java-File encryption method is very simple and important code java

我写的利用IDEA算法的加密程序，并含文件切割和合并功能。-I write using IDEA algorithm encryption procedures, and documents containing cutting and consolidation functions.

一解码程序，挺好的东东，不过是用汇编写的，希望能对大家有所帮助。其中还有一个是hcs系列芯片的接收程序。-a decoding procedure very well, the Eastern, but is the compilation was made in the hope that it can be helpful to everyone. Among them were a series of chips is hcs reception procedures.

不错的希尔代码，希尔是一种经典的加密算法，加密可以通过一线形变换，脱密再做依次逆变换。密钥就是变换矩阵本身。-good code Hill, Hill is a classic encryption algorithms, encryption can transform line shape, followed again from close inverse transform. Key is the transformation matrix itself.

我根据comp430s改写的DLL源码，可在多线程下使用。还带有DES加密算法函数 -DLL source which is overwirted by comp430s, can be used in multi-thread.Attached by DES encryption Algorithm

数据库安全至关重要，尤其是Access数据库，由于其加密算法过于简单，使得Access单靠密码无法保证其安全，本代码通过改变数据库头文件实现对Acess数据库的加密。-Database security is crucial, especially the Access database, because of its too simple encryption algorithm, making Access a password alone can not guarantee their safety, the code by changing the header file database achieve Acess database encryption.
