The CryptoKey dictionary of the Web Crypto API represents a cryptographic key. Available only in secure contexts.

MDN Reference

class ArrayBuffer

Represents a raw buffer of binary data, which is used to store data for the different typed arrays. ArrayBuffers cannot be read from or written to directly, but can be passed to a typed array or DataView Object to interpret the raw buffer as needed.

  • readonly [Symbol.toStringTag]: string
  • readonly byteLength: number

    Read-only. The length of the ArrayBuffer (in bytes).

  • resize(newByteLength?: number): void

    Resizes the ArrayBuffer to the specified size (in bytes).

    resize(byteLength: number): ArrayBuffer

    Resize an ArrayBuffer in-place.

  • slice(begin: number, end?: number): ArrayBuffer

    Returns a section of an ArrayBuffer.

  • transfer(newByteLength?: number): ArrayBuffer

    Creates a new ArrayBuffer with the same byte content as this buffer, then detaches this buffer.

    MDN

  • transferToFixedLength(newByteLength?: number): ArrayBuffer

    Creates a new non-resizable ArrayBuffer with the same byte content as this buffer, then detaches this buffer.
