Crypto

A common set of crypto helpers.

Defines a common interface for crypto implementations between web browsers and Node.js. (Currently only signing/verification and SHA-256 hashing is implemented)

Installation

npm install @casual-simulation/crypto

Usage

// ES6-style imports are required.
// If you are running in an environment that does not support ES Modules,
// then use Webpack or Babel to transpile to the format you want. (like CommonJS)
import { getHash, parsePublicPEMKey } from '@casual-simulation/crypto';

let myHash = getHash('Hello, World');

console.log('Hash: ', myHash);
// Hash: 03675ac53ff9cd1535ccc7dfcdfa2c458c5218371f418dc136f2d19ac1fbe8a5
