@tadashi/signature

Generates and verifies signatures

Install

$ npm i -S @tadashi/signature

Usage

Generate

import {generate} from '@tadashi/signature'

const algorithm = 'sha1'
const payload = '{}'
const secret = 'a7fee042a2e1a9fa27cfc6931949ffe1'

const signature = generate(algorithm, payload, secret)
// => sha1=61ca6afb7b2752e106c939df11bbd7ca883b8166

Verify

import {verify} from '@tadashi/signature'

const signature = 'sha1=61ca6afb7b2752e106c939df11bbd7ca883b8166'
const payload = '{}'
const secret = 'a7fee042a2e1a9fa27cfc6931949ffe1'

const isValid = verify(signature, payload, secret)
// => true

API

generate(algorithm, payload, secret)

parameter | type | required | description ----------- | -------------------- | ----------- | ------------ signature | string | yes | Algorithm that will be used payload | string | yes | Data to generate secret | string | yes | Some expression

verify(signature, payload, secret)

parameter | type | required | description ----------- | -------------------- | ----------- | ------------ signature | string | yes | Algorithm used + hash e.g. sha1=61c...675 payload | string | yes | Data used to generate the hash secret | string | yes | The same expression used to generate
