Overview

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

Interface

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

[NoInterfaceObject]
interface Crypto {
  void getRandomValues(in ArrayBufferView array);
};

Methods

getRandomValues

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 (see below). If array is not of an appropriate type, getRandomValues throws a TYPE_MISMATCH_ERR.
