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.

设f(x)= 1×X2 X5 X27,分别尝试写下面的移位寄存器…
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;

MD5算法的实现。MD5以512位分组来处理输入的信息,且每一分组又被划分为16个32位子分组,经过了一系列的处理后,算法的输出由四个32位分组组成,将这四个32位分组级联后将生成一个128位散列值。
-MD5 algorithm. MD5 to 512 groups to deal with the importation of information and each group was also divided into 16 groups of 32 seats, After a series of processing, the output from the algorithm 4 32 subgroups, 4 32 this group will generate a cascade 128 hash value.
