Detailed Description

compute SHA1 hash

Usage: SHA1 sha1; std::string myHash = sha1("Hello World"); // std::string std::string myHash2 = sha1("How are you", 11); // arbitrary data, 11 bytes

or in a streaming fashion:

SHA1 sha1;
while (more data available)
  sha1.add(pointer to fresh data, number of new bytes);
std::string myHash3 = sha1.getHash();
