sha512

@cryptography/sha512

High-performance synchronous SHA-512 implementation for JavaScript. Optimized for browsers.

Features

• Blazing fast
• Ultra lightweight
• ECMAScript 3-6
• Typed
• Tested

Setup

Package is available through npm and yarn

npm install @cryptography/sha512

yarn add @cryptography/sha512

When you should use @cryptography/sha512

• Hashing small inputs (< 5kb)
• Key derivation functions
• 100% browser support required

⚠️ When you should not use this (WebCrypto API preferred cases)

• Hashing files (> 5kb)
• Concurrent hashing large amount of messages

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 sha512 from '@cryptography/sha512'

// as Uint32Array([0xa8d627d9, ...])
const array = sha512('Hello World!') 

// as hex-string: "a8d627d9..."
const hex = sha512('Hello World!', 'hex')

// as binary string: "Äï�ü�k..."
const raw = sha512('Hello World!', 'binary')

// UInt32Array as input
const buf = new Uint32Array([0xa8d627d9, ...]);
sha512(buf)

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

sha512.stream().update('Hello World!').digest();
