MISTY 加密算法 二进制兼容的加密算法,加密匙可到128位

在Visual C++ 6.0下利用Rijndael算法进行任意文件加密，一个rijndael加密算法的使用实例，虽然图形界面做得比较粗糙，但是程序本身有很多值得参考和学习的地方- 6.0 carries on the free document encryption in Visual C using the Rijndael algorithm, a rijndael encryption algorithm use example, although the graphical interface does quite roughly, but procedure itself has the very multiple-valued reference and the study place

这是密码学软件源码,一个小程序的源码,caser密码-This is the source cryptography software, a source of small procedures, caser password

AES加密软件，用于加密当前文本框中的内容。使用的是美国国家标准（也被ISO所采纳）最新加密算法AES。-AES encryption software, encryption for the current contents of the text box. The use of the American National Standards (also adopted by the ISO) the latest encryption algorithm AES.

一个不错的文件加密系统，对你工作的安全大大加强。-a good file encryption system, you have the right security greatly enhanced.

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;

修正了原CMd5类的CaculateStr函数的严重错误，并且转到新的C++类库。此类已经经过验证，文件和字符串均能得到正确结果，支持Unicode（Unicode时不需要转换）-amendment of the original CMd5 CaculateStr function of the type of serious errors and to the new C Class. Such has been validated, documents, and the string to get the correct result, Unicode support (Unicode does not need conversion)
