• A certificate manager for my applications
• self signed X.509 certificates

• Create certificates
• Read (list all certificates)
• Download a certificate and private key
• Delete a certificate
• View openAPI specs

• SQLite (hosted in the same container)

• Certificates
  • ID
  • name (subject name)
  • certificate
  • PrivateKey

• These don't need database as they are part of the integration tests.
• Frontend is also not unity tested, as E2E testing would be more useful.

• These are needed for database testing

• NodeJS
• Express based HTTP RESTapi
• JavaScript
• Docker with SQLite
• Bash script for starting the docker
• node-forge for certificates

• JavaScript
• HTML
• CSS
• basic form validation, which is also done on the backend for security
• easy to understand user interface for:
  • creating certificate
  • listing the user's certificates
  • deleting the user's certificate
  • downloading a certificate and the private key

• Swagger OpenAPI

• src contains the project
  • Dockerfile for build a Docker image
  • app.js contains the main server code
  • buildandstartdocker.sh builds and starts the server
  • buildandtestDocker.sh builds and runs the tests
  • certapi.yaml openAPI document
  • certs/certs.js has the server certificate utilities
  • db/db.js has the SQLite Database code and SQL commands
  • jest.config.js test environment setup
  • package.json contains NodeJS configuration with needed dependencies
  • public/favicon.ico website icon
  • public/index.html main frontend HTML and CSS is here
  • public/index.js main frontend logic in JavaScript
  • test/integration/database.spec.js has integration test for DB as UT is not sufficient.
  • test/unit/app.spec.js has unit tests for the functions and endpoints for main app.js
  • test/unit/certs/certs.spec.js has unit tests for the certification utilities

• The project has been tested on an m1 Mac and X86 Linux It can be run natively or with docker

server:

cd src
bash buildandstartdocker.sh

Open browser and navigate to: http://localhost:3000

test:

cd src
bash buildandtestDocker.sh

Install NodeJS

cd src
npm install
node app.js

Open browser and navigate to: http://localhost:3000

test:

cd src
npm install
npm test

• shift, option, F does pretty printing in JS
• future ideas:
  • Certificate signing requests to avoid leaking private key
  • MFA and a reverse proxy with multiple users
  • Support for multiple CAs
  • performance tests with K6
