Detailed Description

compute SHA3 hash

Usage: SHA3 sha3; std::string myHash = sha3("Hello World"); // std::string std::string myHash2 = sha3("How are you", 11); // arbitrary data, 11 bytes

or in a streaming fashion:

SHA3 sha3;
while (more data available)
  sha3.add(pointer to fresh data, number of new bytes);
std::string myHash3 = sha3.getHash();
