DES加密算法C语言实现，我以将它成功的移植到Nios处理器上

高级加密算法实现AES,已经被美国NIST机构采用-advanced encryption algorithm AES, the United States has been using NIST agencies

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;

在原作者Jim Gillogly代码的基础上修改优化，并实现C++改写。实现了DES加密。当然，密钥可在源文件中修改，或提供修改的接口函数。-the originator Jim Gillogly code revision on the basis of optimization, and to achieve C rewritten. Implementation of DES encryption. Of course, the key in the source documents changes, or amendments to provide the interface function.
