@cryptography/sha256
High-performance synchronous SHA-256 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/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'
// as Uint32Array([0xa8d627d9, 0x3f518e90, 0x96b6f40e, 0x36d27b76, 0x60fa26d3, 0x18ef1adc, 0x43da750e, 0x49ebe4be])
const array = sha256('Hello World!')
// as hex-string: "a8d627d93f518e9096b6f40e36d27b7660fa26d318ef1adc43da750e49ebe4be"
const hex = sha256('Hello World!', 'hex')
// as binary string: "ÄïükYoUH½LÛ,Zß\nNÆêE©¡`M¢"
const raw = sha256('Hello World!', 'binary')
// UInt32Array as input
const buf = new Uint32Array([0xa8d627d9, 0x3f518e90, 0x96b6f40e, 0x36d27b76, 0x60fa26d3, 0x18ef1adc, 0x43da750e, 0x49ebe4be]);
sha256(buf)
For hashing large files or other data chuncks use stream()
to create a hashing stream.
sha256.stream().update('Hello World!').digest();
Benchmarks
Faster than forge, sjcl and WebCrypto API in sequence mode.
2x faster at desktop browsers (benchmarked with Macbook Pro 2016)
4x faster at mobile browsers (benchmarked with iPhone 6S 13.2)
