As you have mentioned c++, here is an answer. Iomanip is used to store ints in hex form into stringstream.

#include 
#include 

std::string hexStr(BYTE *data, int len)
{
     std::stringstream ss;
     ss << std::hex;

     for( int i(0) ; i < len; ++i )
         ss << std::setw(2) << std::setfill('0') << (int)data[i];

     return ss.str();
}
