RFC-1321 describes the MD5 steps and includes the original reference implmentation.
http://www.rfc.net/rfc1321.html[^]
I assume you want to do this for educational purposes. Otherwise it would be better to use Microsoft cryptographic service providers.

MD5 is a hash, it only goes from plain-text to hashed data. It does not go the other way. If you want to go back and forth, you need to look at cryptography, not hashing.

You could also use GetEnvironmentVariable:
TCHAR tcDirName[_MAX_PATH];
GetEnvironmentVariable(_T("userprofile"), tcDirName, _MAX_PATH);
This environment variable is set when the user logs on.
Note that it is not always on the same drive as the system (C .
Hope that helps.

Thanks for your reply, is there any specific win32 API who will do this job. As i need to use this in win32 API programming, not in MFC or higher framwork.

Yes, use
GetUserProfileDirectory - retrieves the path to the root directory of the specified user's profile.
For e.g. C:\Documents and Settings\Nibu
A function which uses ths API to return current process user home dir...
#include "Userenv.h"
#pragma comment(lib, "userenv.lib")
CString GetUserHomeDir()
{
TCHAR szHomeDirBuf[MAX_PATH] = { 0 };
HANDLE hToken = 0;
VERIFY( OpenProcessToken( GetCurrentProcess(), TOKEN_QUERY, &hToken ));
DWORD BufSize = MAX_PATH;
VERIFY( GetUserProfileDirectory( hToken, szHomeDirBuf, &BufSize ));
CloseHandle( hToken );
return CString( szHomeDirBuf );
}
Then there are other functions too which might interest you, like...
GetAllUsersProfileDirectory
GetDefaultUserProfileDirectory
GetProfilesDirectory
Look up these in MSDN for more information.

Is the given code correct?
I am wondering about the return instruction, in which a CString object is created:
return CString( szHomeDirBuf );
In my opinion this object will be already destroyed while the function returns.
When accessing from caller, the object is already invalid.
CString res = GetUserHomeDir();
Am I wrong?

hi, well, im currently using visual studio 2003 to compile or attempt to compile a Half life 2, AKA. a source mod, but i get 2 errors and im having trouble getting rid of them so i can compile the *.dll file, i get these errors as follows:
Error C2062: Type 'void' unexpected
Error C2447: '{': missing function header (old-style formal list?)
the code seems to be correct and should work but those 3 errors are prohibiting me from compiling the *.dll file, any help would be great apreaciated.
(i have attached the small block of code that the errors point too)
CWeaponDualies( void )
{
m_flSoonestPrimaryAttack = gpGlobals->curtime;
m_flAccuracyPenalty = 0.0f;
m_fMinRange1 = 24;
m_fMaxRange1 = 1500;
m_fMinRange2 = 24;
m_fMaxRange2 = 200;
m_bFiresUnderwater = true;
}

What happens when you remove void ?
|
|
|
|
|
it removes 1 of the errors, thanks for pointing that error out, but i still get this error:
Error C2447: '{' missing function header style (old-style formal list?)
|

Check if the function has an appropriate function declaration.
Google for the error "C2447". There are several solutions to solve this.

Weird problem I have this function (is a function changed I used it to another purpose)
void browseFolder(TCHAR *path, TCHAR *initial)
{
WIN32_FIND_DATA FindFileData;
HANDLE hFind=INVALID_HANDLE_VALUE;
TCHAR dir[MAX_PATH];
TCHAR aux[MAX_PATH];
StringCchCopy(aux, MAX_PATH, path);
StringCchCat(aux, MAX_PATH, TEXT("\\*"));
hFind= FindFirstFile(aux,&FindFileData);
do
{
if (FindFileData.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY)
{
if((_tcscmp (FindFileData.cFileName, _T(".")) != 0) && (_tcscmp (FindFileData.cFileName, _T("..")) != 0))
{
StringCchCopy(dir, MAX_PATH, path);
StringCchCat(dir, MAX_PATH, TEXT("\\"));
StringCchCat(dir, MAX_PATH, FindFileData.cFileName);
browseFolder(dir,initial);
}
}
else
{
TCHAR pathFileName[MAX_PATH];
StringCchCopy(pathFileName, MAX_PATH, path);
StringCchCat(pathFileName, MAX_PATH, TEXT("\\"));
StringCchCat(pathFileName, MAX_PATH, FindFileData.cFileName);
CString szMessage;
szMessage.Format(_T("%s"),pathFileName);
_tprintf(_T("%s\n"),szMessage);
DeleteFile(szMessage);
}
}
while (FindNextFile(hFind, &FindFileData) != 0);
hFind= INVALID_HANDLE_VALUE;
_tprintf(path);
RemoveDirectory(path);
}</dir>
The function delete all the files but lives the folders intact I cannot understand why. Seems like they are in use and they cannot be deleted....
