crypto.getRandomValues(typedArray)

• typedArray <Buffer> | <TypedArray>

• 返回：<Buffer> | <TypedArray>

  ¥Returns: <Buffer> | <TypedArray>

生成加密强随机值。给定的 typedArray 填充了随机值，并返回对 typedArray 的引用。

¥Generates cryptographically strong random values. The given typedArray is filled with random values, and a reference to typedArray is returned.

给定的 typedArray 必须是 <TypedArray> 的基于整数的实例，即不接受 Float32Array 和 Float64Array。

¥The given typedArray must be an integer-based instance of <TypedArray>, i.e. Float32Array and Float64Array are not accepted.

如果给定的 typedArray 大于 65,536 字节，将抛出错误。

¥An error will be thrown if the given typedArray is larger than 65,536 bytes.
