Re: STATUS_STACK_BUFFER_OVERRUN encountered

Hi I am calling a function from MFC dll in C# application.
This function work with C++ application but when I was calling from C#
application terminates unexpectedly.

can anyone tell me why this happening?

I am pasting my source code here
---------------------------------------------------
C# code
--------------
       private void button1_Click(object sender, EventArgs e)
       {
           string strPassWord = textBox1.Text;
           string strHash = "";
           PasswordHash(strPassWord,ref strHash);
           MessageBox.Show(strHash);
       }

-----------------
PasswordHash function in my MFC regular statically linked to MFC dll
C++ code

bool __stdcall PasswordHash(LPCTSTR lpPassword, LPTSTR lpszHash)
{
AFX_MANAGE_STATE(AfxGetStaticModuleState());
CString strPassword(lpPassword);
bool bReturn = false;
HCRYPTPROV hCryptProv;
HCRYPTHASH hHash=NULL;
BYTE pbHash[16];
DWORD dwHashLen= 16;
DWORD cbContent= strPassword.GetLength() * sizeof(TCHAR);
BYTE* pbContent= (BYTE *) strPassword.GetBuffer(cbContent);

if(CryptAcquireContext(&hCryptProv, NULL, NULL, PROV_RSA_FULL,
CRYPT_VERIFYCONTEXT | CRYPT_MACHINE_KEYSET))
{
if(CryptCreateHash(hCryptProv,CALG_MD5,0, 0, &hHash))
{
if(CryptHashData(hHash, pbContent, cbContent, 0))
{
if(CryptGetHashParam(hHash, HP_HASHVAL, pbHash, &dwHashLen, 0))
{
LPTSTR lpTmp = lpszHash;
for (int i = 0; i < 16; i++)
{
const size_t nlen = sizeof(pbHash[i])+2;
_stprintf_s(lpTmp,nlen,_T("%02X"),pbHash[i]);
lpTmp += 2;
}
bReturn = true;
}
}
}
}
CryptDestroyHash(hHash);
CryptReleaseContext(hCryptProv, 0);
return bReturn;
}
