please don't forget to call SetLimit(buffer_limit - 1) after getting ByteBuffer from StringToUtf8N(). e.g.

String test(L"test");
ByteBuffer* out = StringUtil::StringToUtf8N(test);
out->SetLimit(out->GetCapacity() - 1);

according to dev guide, StringToUtf8N() function returns ByteBuffer and "The buffer's limit is the length of the string plus one and the starting position is 0". so your buffer should be "-1"

Eureka, it works now ! Thanks, man!

Hi, Levan !

voila:

String XXXXXXXXXXX::LeftPadZero(String s, int wantedLen) {
    int prependCount = (wantedLen - s.GetLength()); 
    if (prependCount <= 0) return s; // nothing to do
    //==
    String sPreffix = "0";
    for (int i=1; i < prependCount; i++) sPreffix = "0" + sPreffix;
    return sPreffix + s;
}

// hashing
String XXXXXXXXXXX::MD5(String s) {
    ByteBuffer* pInput = StringUtil::StringToUtf8N(s);
    pInput->SetLimit(pInput->GetCapacity() - 1);

    Md5Hash md5;
    ByteBuffer* pOutput = md5.GetHashN(*pInput);
    String sHash;

    {
        int byteCount = pOutput->GetLimit();

        for (int i = 0; i < byteCount; i++) {
            byte b;  pOutput -> GetByte(i, b);
            unsigned int ui = b;
            String sHex;
            sHex.Format(25, L"%02x", ui);
            sHash.Append(sHex);
        }
    }

    delete pInput;
    delete pOutput;

    // should return 32 bytes
    sHash = LeftPadZero(sHash, 32);

    ///
    return sHash;
}
