Secret helper library


A simple little library built using Typescript that helps:

  • Create API keys
  • Create salts
  • Create hashes
  • Validates hashes

Check it out on Github:


npm install @subgeniuscorp/secret-helper

Basic usage

const secretHelper = require("@subgeniuscorp/secret-helper"); // Setup const config = { saltLength: 5, // defaults to 30 apiKeyLength: 20, // defaults to 30 }; const sh = secretHelper(config); // Usage const apiKey = sh.generateApiKey(); const salt = sh.generateSalt(); const hash = sh.createHash("some string"); const secretIsValid = sh.validateHash({ hashValue: "jQHg1ed6d0b28cb5be10171f15204b9626990", valueToCompare: "some string", });


When I was working on my leaderboard API project, I noticed I was sharing some helper functions between the Next.js project and the Heroku express.js project. Since the Next and express apps need to make sure they use the same functions, this was a great little use-case to abstract this into an npm package, and build something in Typescript, which I've been putting off for a while.

The library uses Node's crypto module for creating hashes and api keys.
