Detailed Description

compute Keccak hash (designated SHA3)

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

or in a streaming fashion:

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