DES

仿射 suanfa daima 加密 解密(affine suanfa daima affine )

用C/C++实现加解密算法及其应用：DES（或AES）和基于DES（或AES）的CMAC。(With C/C++ achieve encryption and decryption algorithm and its application: DES (or AES) and based on DES (or AES) of CMAC.)

此为Keeloq算法的解密C代码，keeloq最常用于无线门锁装置。(KeeLoq is a proprietary hardware-dedicated NLFSR-based block cipher. The uni-directional command transfer protocol was designed by Frederick Bruwer, PhD, CEO at Nanoteq (Pty) Ltd)

sha256计算代码，非常好用的代码，大家可以用这个代码直接计算哈希值，sha256实现 依次执行 SHA256Init、 SHA256Update SHA256Final 三个函数即可得到sha256结果(sha256 sourse code，Is very usefull)

MD5是一种被广泛使用的“消息-摘要算法”。实际上就是一个单项散列函数。(MD5 is a widely used " message- digest algorithm." Is actually a single hash function.)

说明：  idea算法VC++源码，包含系列文件 idea.h idea.cpp ideadlg.h ideadlg.cpp resource.h stdafx.h stdafx.c(idea algorithm VC++ source, including the series of documents idea.hidea.cppideadlg.hideadlg.cppresource.hstdafx.hstdafx.c)

这只是标准DES算法的例子,必须在WINDOWS环境下编译.(This is just the standard DES algorithm, which must be compiled in the WINDOWS environment.)

基于VB的M5数学密码算法源码,有需要的就下载吧。(VB-based M5 mathematical algorithm source code, there is a need to download it.)

对txt文件的加密解密，采用c++编写。(The encryption and decryption of the txt file, using c ++.)

支持椭圆曲线运算的大数运算库和源程序，头文件和静态库可以使用。(Support for elliptic curve operations of large numbers arithmetic library and source code, header files and static libraries can be used.)
