stable-sha1

Get a consistent sha1 hash for a JSON object in both browser and node

Inspired by shasum, but unlike shasum it is only 3.6KB once minified and gzipped. It does this by only supporting shasums for objects, not for buffers. It also achieves further savings by assuming a browser with support for JSON and using the relatively lightweight rusha instead of the very large crypto-browserify.

Installation

npm install stable-sha1

Usage

'use strict';

var assert = require('assert');
var sha = require('stable-sha1');

assert(sha({a: 1, b: 2, z: 3}) === sha({z: 3, b: 2, a: 1}));
assert(sha({a: 1, b: 2, z: 3}) !== sha({z: 3, b: 2, a: 2}));
