sample.c

使用c语言实现的DES加解密算法。控制台程序。

#include "stdio.h"
#include "des.h"



void main()

unsigned char m_bit[8]={'a','b','b','x','y','z','m','n'} ;/*uncode*/

unsigned char e_bit[8]={0x0,0x0,0x0,0x0,0x0,0x0,0x0,0x0} ;/*encode*/
/*Sample Data*/
int i=0 ;

//printf("\nThis is a sample for DES function by Atan 1998/02/28") ;
//printf("\nPassword is : [ZWgjVgn") ;
printf("\nUncryption Data:") ;
