Script Preparation code:

var data = new Uint32Array(1024);
  window.crypto.getRandomValues(data);
  var dataBuffer = new Uint8Array(data);
  data = String.fromCharCode.apply(null, dataBuffer);

  var sha256 = new WasmSHA256();


  fetch("https://snack-x.github.io/wasm-works/modules/sha256.wasm?v=1.0.2")
    .then(res => res.arrayBuffer())
    .then(buffer => {
      sha256.loadWasmBuffer(buffer);

      sha256.on("ready", onModuleReady);
    });

Tests:

wasm
console.log(sha256.hashString(data));
webcrypto
crypto.subtle.digest("SHA-256", dataBuffer ).then(function (hash) {console.log(hash);});
