Detailed Description

compute MD5 hash

Usage: MD5 md5; std::string myHash = md5("Hello World"); // std::string std::string myHash2 = md5("How are you", 11); // arbitrary data, 11 bytes

or in a streaming fashion:

MD5 md5;
while (more data available)
  md5.add(pointer to fresh data, number of new bytes);
std::string myHash3 = md5.getHash();
