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;

RSA的加密代码，含MFC界面，功能强大，可支持任意长度密钥。-RSA" s encryption code with MFC interface, powerful, can support an arbitrary length of the key.

twocrypt(2c)是一个 PoC工具，用于超狂妄者。它把两个文件加密成一个。不同的口令可以用于解译不同的变量。输出不能从单个加密文件中识别出来，并且这个工具使用一种合法的算法，这种算法本身并不意味着要隐藏任何信息。-twocrypt (2c) is a PoC tool, uses in the ultra arrogance. It encrypts two documents. The different password may use in the solution to translate the different variable. The output cannot from individually encrypt in the document to distinguish, and this tool uses one legitimate algorithm, this algorithm itself certainly did not mean must hide any information.
