std::wstring hashStr(L"4727b105cf792b2d8ad20424ed83658c");
//....
byte digest[16];
How can I get my md5 hash in digest? My answer is:
wchar_t * EndPtr;
for (int i = 0; i < 16; i++) {
std::wstring bt = hashStr.substr(i*2, 2);
digest[i] = static_cast<BYTE>(wcstoul(bt.c_str(), &EndPtr, 16));
}
You need to read two characters from hashStr
, convert them from hex to a binary value, and put that value into the next spot in digest
-- something on this order:
for (int i=0; i<16; i++) {
std::wstring byte = hashStr.substr(i*2, 2);
digest[i] = hextobin(byte);
}
C-way (I didn't test it, but it should work (though I could've screwed up somewhere) and you will get the method anyway).
memset(digest, 0, sizeof(digest));
for (int i = 0; i < 32; i++)
{
wchar_t numwc = hashStr[i];
BYTE numbt;
if (numwc >= L'0' && numwc <= L'9') //I assume that the string is right (i.e.: no SGJSGH chars and stuff) and is in uppercase (you can change that though)
{
numbt = (BYTE)(numwc - L'0');
}
else
{
numbt = 0xA + (BYTE)(numwc - L'A');
}
digest[i/2] += numbt*(2<<(4*((i+1)%2)));
}
