• Tested`

Setup

Package is available through npm and yarn

npm install @cryptography/sha256

yarn add @cryptography/sha256

Usage

This package is optimized for small byte inputs (<10kb).

Also, it is highly recommended to run CPU-intensive tasks in a Web Worker.

import sha256 from '@cryptography/sha256'

const hash = sha256('Hello World!')
const bytes = sha256('Hello World!', 'array')

For hashing large files or other data chuncks use stream() to create a hashing stream.

sha256.stream().update('Hello World!').digest();

Faster than forge, sjcl and WebCrypto API in sequence mode.
