This document describes a proposal for the window.crypto API.


[Suplemental, NoInterfaceObject]
interface Window {
  readonly attribute Crypto crypto;

interface Crypto {
  void getRandomValues(in ArrayBufferView array);



The getRandomValues method fills array with random data. Specifically, if array is an ArrayBufferView of an integer type (i.e., Int8Array, Uint8Array, Int16Array, Uint16Array, Int32Array, or Uint32Array), then all the elements of array are overwritten with cryptographically random values. If array is not of an appropriate type, getRandomValues throws a TYPE_MISMATCH_ERR. If no cryptographically random values are available, getRandomValues throws a NOT_SUPPORTED_ERR.
