sha256-uint8array

sha256-uint8array

Fast SHA-256 digest hash based on Uint8Array, pure JavaScript.

SYNOPSIS

const createHash = require("sha256-uint8array").createHash;

const text = "";
const hex = createHash().update(text).digest("hex");
// => "e3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855"

const data = new Uint8Array(0);
const hash = createHash().update(data).digest();
// => <Uint8Array e3 b0 c4 42 98 fc 1c 14 9a fb f4 c8 99 6f b9 24 27 ae 41 e4 64 9b 93 4c a4 95 99 1b 78 52 b8 55>

The interface is a subset of Node.js's crypto module. See TypeScript declaration sha256-uint8array.d.ts for detail.

BENCHMARK

Node.js's native crypto module run faster than others on Node.js. sha256-uint8array runs well both on Node.js and browsers with its smaller footprint.
