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.)

AES加解密C语言源代码，可直接运行通过，方便大家借鉴学习(AES encryption and decryption of C language source code, can be directly run by, we facilitate learning from)

一个袖珍的vc++加密软件，同时还可以解密，加密文件的范围挺大的，几乎所有文件都可以加密，输入密码并解密，好像不是真正意义的加密，只不过是用文件额外加密的方法进行加密，较早时候的程序，不过编译还是顺利的。 (A pocket-sized vc++ encryption software, but also can decrypt encrypted files the scope of getting bigger, almost all the files can be encrypted, enter the password and decrypt the encryption does not seem real, but the file is an additional method of encryption to encrypt Earlier procedures, but the compiler is still smooth.)

检测CRC编码 看CRC编码在传输后是否有错误 有变动 (Detection CRC codes to see whether the CRC coding errors in the transmission there is a change)

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 !)

二进制文件操作工具 可以对二进制文件合并、分拆、加密、解密的工具，再对两个可执行文件进行合并后，显示第一个文件的信息，并且正常使用，第二个被忽略。(Binary file binary file manipulation tools can merge, split, encrypt, decrypt tool, and then the merger of two executable files, show the first file, and normal use, the second is ignored.)

本源代码，综合了DES，RSA,MD5等几种加密的方法于同一工程中，可以让读者对各种加密方法的实现通过代码实现过程的比较，更好的理解几种软件加密方法(Source code, a combination of DES, RSA, MD5 encryption method, such as several in the same project, will allow readers to a variety of encryption methods to achieve the realization of the process through code comparison, a better understanding of several software encryption methods)

基于LSB的信息隐藏技术——MFC——编译已经通过运行正常(LSB-based Information Hiding- MFC- has been compiled by running the normal)

rsa 实现代码，运用大数算法#include "afx.h" #include "Integer.h" #include <string> #include <iostream> using namespace std //构造大数对象并初始化为零 CInteger::CInteger() { m_nLength=1 for(int i=0 i<BI_MAXLEN i++)m_ulValue[i]=0 } //解构大数对象 CInteger::~CInteger() { } /*大数比较 调用方式：N.Cmp(A) 返回值：若N<A返回-1；若N=A返回0；若N>A返回1 */ int CInteger::Cmp(CInteger& A)(#include "afx.h" #include "Integer.h" #include <string> #include <iostream> using namespace std //构造大数对象并初始化为零 CInteger::CInteger() { m_nLength=1 for(int i=0 i<BI_MAXLEN i++)m_ulValue[i]=0 } //解构大数对象 CInteger::~CInteger() { } /*大数比较 调用方式：N.Cmp(A) 返回值：若N<A返回-1；若N=A返回0；若N>A返回1 */ int CInteger::Cmp(CInteger& A))
