Re: [boost] [crypto] remove snprintf in message_digest::to_string() for msvc

Hello Chris!

of message_digest. It uses snprintf which isn't readily available in MSVC (vs 2005 at least) so I rewrote it using some bit twiddling:

Actually it uses sprintf, not snprintf. It's possible that the old msvc lib does not promote sprintf to the std namespace so it will not find the std::sprintf() call. I could simply add a using namespace std. I will consider your version though since it should be faster. Kevin
