使用开源代码CSHA1 - A，计算文件和字符串SHA1

void GetSHA()
{
int iIndex = -1;
CSHA1 sha1;
do
{
printf("输入数字选择想校验SHA1的类型：\nFile is 1 \nString is 2 \nExit is 3 \r\n");
scanf("%d",&iIndex);
if (iIndex == 1)
{
TCHAR str[] = {0};
printf("请输入文件名全路径或者直接拖到DOS窗口\n");
scanf("%s",str);
sha1.HashFile(str);
sha1.Final();
TCHAR tszReport[41];
sha1.ReportHash(tszReport, CSHA1::REPORT_HEX_SHORT);
_tprintf(_T("\r\n File hashed to:\r\n "));
_tprintf(tszReport);
_tprintf(_T("\n"));
}
if (iIndex == 2)
{
char chTemp[128] = {0};
printf("请输入字符串\r\n");
scanf("%s",chTemp);
sha1.Update(reinterpret_cast<const unsigned char*>(chTemp), strlen(chTemp));
sha1.Final();
std::basic_string<TCHAR> strReport;
sha1.ReportHashStl(strReport, CSHA1::REPORT_HEX_SHORT);
_tprintf(_T("\r\n String hashed to:\r\n "));
_tprintf(strReport.c_str());
_tprintf(_T("\r\n"));
//          std::cout<<"Hash is :["<<hex<<strReport.c_str()<<"]"<<endl;

}
sha1.Reset();
} while (iIndex != 3);
}
