Syntax

sha256(value, outputFormat?)

Parameters

• value

  A string, a Uint8Array, a Int8Array, or an ArrayBuffer to hash. If a string, it will be UTF-8 encoded into bytes.

• outputFormat optional

  The format of the hash digest: "hex" or "bytes". Defaults to "hex". If "hex", the return value will be a hex string. If "bytes", the return value will be a Uint8Array.

Return value

A hex string or a Uint8Array representing the hash digest.

Example

sha256("hello")
