test_main.cpp

一个叫尹学渊的人写的DES的程序,注释的非常详细.适合那些对C++不是很精通的人.

#include <stdio.h>
#include "yxyDES.h"
//主函数中只有密钥初始化,加密,解密这几个函数
void main()
{
	yxyDES* my_des = new yxyDES();  //密钥初始化
	char temp[32] = {0};
	my_des->InitializeKey("security");   
	//用到InitializeKey和CreateSubKey函数
	printf("key is : security \n");
	my_des->EncryptAnyLength("computer");  //加密
	printf("set plaintext : computer \n");
	printf("after encrypt : %s \n",my_des->GetCiphertextAnyLength());
	printf("now,decrypting...\n");
	my_des->DecryptAnyLength("379cb171b20d7a23");  //解密
	printf("after decrypt : %s \n",my_des->GetPlaintextAnyLength());
	getchar();
}
