ohash

Super fast hashing library written in Vanilla JS

Usage

Install package:

# npm
npm install ohash

# yarn
yarn add ohash

# pnpm
pnpm install ohash

Import:

// ESM
import { hash, objectHash, murmurHash, sha256 } from 'ohash'

// CommonJS
const { hash, objectHash, murmurHash, sha256 } = require('ohash')

Converts object value into a string hash using objectHash and then applies sha256 with Base64 encoding (trimmed by length of 10).

Usage:

import { hash } from 'ohash'

// "dZbtA7f0lK"
console.log(hash({ foo: 'bar' }))

Converts a nest object value into a stable and safe string for hashing.

Usage:

import { objectHash } from 'ohash'

// "object:1:string:3:foo:string:3:bar,"
console.log(objectHash({ foo: 'bar'}))

Converts input string (of any length) into a 32-bit positive integer using MurmurHash3.

Usage:

import { murmurHash } from 'ohash'

// "2708020327"
console.log(murmurHash('Hello World'))

Create a secure SHA 256 digest from input string.

import { sha256 } from 'ohash'

// "a591a6d40bf420404a011733cfb7b190d62c65bf0bcda32b57b277d9ad9f146e"
console.log(sha256('Hello World'))

Create a secure SHA 256 digest in Base64 encoding from input string.

import { sha256base64 } from 'ohash'

// "pZGm1Av0IEBKARczz7exkNYsZb8LzaMrV7J32a2fFG4"
console.log(sha256base64('Hello World'))
