hash-object

Get the hash of an object

Original version used node-specific node:crypto import syntax which made it incompatible with webpack. Slightly modified it to fit my needs, that's all.

Install

npm install @gummy47/hash-object

Usage

import hashObject from 'hash-object';

hashObject({'🦄': '🌈'}, {algorithm: 'sha1'});
//=> '3de3bc784035b559784fc276f47493d60555fba3'

API

hashObject(object, options?)

The output is deterministic for repeated runs on the same Node.js / browser version. It should also be fairly deterministic across JavaScript engines. However, because the stability of grapheme clusters across Unicode versions is not guaranteed, determinism cannot be guaranteed across JavaScript engines and versions. There are also other factors that can make it nondeterministic, like values with floating point numbers and dates.

object

Type: object

options

Type: object

encoding

Type: 'hex' | 'base64' | 'buffer' | 'latin1'
Default: 'hex'

The encoding of the returned hash.

algorithm

Type: string
Default: 'sha512'
Values: 'md5' | 'sha1' | 'sha256' | 'sha512' | … (Platform dependent)

Don't use 'md5' or 'sha1' for anything sensitive. They're insecure.
