基于字符串加密的MD5算法，VS2008 VC++，多字节编译工程。主要代码如下，实现了ANSI字符串加密与Unicode字符串加密。
运行效果如下：
核心代码：
void CEncryptByMd5Dlg::OnButtonOk()
{
// TODO: Add your control notification handler code here
UpdateData(true);
unsigned int len=0;
char *cTemp =NULL;
if(m_bType==0)
{
len=m_sText.GetLength();
cTemp=(char*)(LPCTSTR)m_sText;
}
else
{
len=CStringW(m_sText).GetLength()*2;
cTemp=(char*)ANSI2UNICODE(m_sText);
}
char *cIdentity;
CMd5A md5;
cIdentity = md5.MDString(cTemp,len);
m_sEncrypt = CString(cIdentity);
if(m_bUpper==TRUE)
{
m_sEncrypt.MakeUpper();
}
else
{
m_sEncrypt.MakeLower();
}
UpdateData(false);
}
void CEncryptByMd5Dlg::OnBnClickedBtnCompare()
{
// TODO: Add your control notification handler code here
UpdateData(true);
if(m_sEncrypt==m_szMD5_2)
{
MessageBox(_T("密文比较结果相同!"),_T("比较相同"),MB_OK|MB_ICONINFORMATION);
}
else
{
MessageBox(_T("密文比较结果失败！"),_T("比较不同"),MB_OK|MB_ICONERROR);
}
UpdateData(FALSE);
}
void CEncryptByMd5Dlg::OnEnChangeEdit1()
{
// TODO: If this is a RICHEDIT control, the control will not
// send this notification unless you override the CDialog::OnInitDialog()
// function and call CRichEditCtrl().SetEventMask()
// with the ENM_CHANGE flag ORed into the mask.
OnButtonOk();
// TODO: Add your control notification handler code here
}
char * CEncryptByMd5Dlg::Unicode2ANSI(CString strSource)
{
if (strSource.IsEmpty()) return NULL;
char *pBuffer = NULL;
int nBufferSize = 0;
#ifdef _UNICODE
nBufferSize = WideCharToMultiByte(CP_ACP, 0, (LPCTSTR)strSource, -1, NULL, 0, NULL, NULL) + 1;
pBuffer = new char[nBufferSize];
memset(pBuffer, 0, sizeof(char)*nBufferSize);
WideCharToMultiByte(CP_ACP, 0, (LPCTSTR)strSource, -1, pBuffer, nBufferSize, NULL, NULL);
#else
nBufferSize = strSource.GetLength() + 1;
pBuffer = new char[nBufferSize];
memset(pBuffer, 0, sizeof(char)*nBufferSize);
strcpy_s(pBuffer, nBufferSize, (LPCTSTR)strSource);
#endif
return pBuffer;
}
wchar_t * CEncryptByMd5Dlg::ANSI2UNICODE(CString pData)
{
int nLength = MultiByteToWideChar(CP_ACP, 0, pData, -1, NULL, 0);
wchar_t *pwBuffer = new wchar_t[nLength + 1];
memset(pwBuffer, 0, sizeof(wchar_t)*(nLength + 1));
MultiByteToWideChar(CP_ACP, 0, pData, -1, pwBuffer, nLength);
return pwBuffer;
}
void CEncryptByMd5Dlg::OnBnClickedCheckUpper()
{
OnButtonOk();
// TODO: Add your control notification handler code here
}
void CEncryptByMd5Dlg::OnBnClickedRadio1()
{
OnButtonOk();
// TODO: Add your control notification handler code here
}
void CEncryptByMd5Dlg::OnBnClickedRadio2()
{
OnButtonOk();
// TODO: Add your control notification handler code here
