Crypto Service

This app provides basic crypto and blockchain-related functions including:

• generating public/private key pairs
• signing transactions
• encrypting / decrypting payloads - supporting both symmetric and asymmetric encryption
• decrypt and re-encrypt with different keys - in a single call

This service is mostly stateless - it holds no user data or keys - but it does hold developer (app) registrations in order to issue api keys

Starting service

• Create .env file in project's root directory - copy .env.example to .env and replace values

• Generate a public/private Key pair for server's use (see .env.example BASE_PUBLIC_KEY, BASE_PRIVATE_KEY)

• Important: Run Node 12.0 or higher on your local machine

• npm run dev

  Runs the service in the development mode
  Open http://localhost:8080 to view it in the browser.

• npm run build

  Builds the app for production into the `dist folder.
  

• npm run start

  Runs the app in production mode. Expects that npm run build has been run.
  

Environment Config

• Configuration and secrets are stored in .env in the root of the app folder
• .env files are never checked-into the github repo (excluded via .gitignore)

Example Code

• examples/helpers.ts provides code you can use to generate auth tokens, etc.

• examples/demo.ts contains example code to call the API endpoints. To run demo code:

  ts-node examples/demo.ts
