Example usage:

var multiHashing = require("multi-hashing");

var algorithms = [
  "quark",
  "x11",
  "scrypt",
  "scryptn",
  "keccak",
  "bcrypt",
  "skein",
  "blake",
];

var data = new Buffer(
  "7000000001e980924e4e1109230383e66d62945ff8e749903bea4336755c00000000000051928aff1b4d72416173a8c3948159a09a73ac3bb556aa6bfbcad1a85da7f4c1d13350531e24031b939b9e2b",
  "hex"
);

var hashedData = algorithms.map(function (algo) {
  return multiHashing[algo](data);
});

console.log(hashedData);
