RSA算法的C++实现。公钥加密算法中使用最广的是RSA。RSA算法研制的最初理念与目标是努力使互联网安全可靠，旨在解决DES算法秘密密钥的利用公开信道传输分发的难题。-RSA algorithm is the C++ implementation. Public key encryption algorithm is the most widely used is RSA. RSA algorithm is developed by the original idea and objective is to make the Internet safe and reliable, aimed at resolving the DES algorithm is a secret key transmitted using the open channel distribution problems.

今天我们学习了des对称加密算法这是一个des算法的C++实现-This is a des !

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;
