I Turned My University Java Project Into an Open Source Auth Toolkit

I was jobless and needed to build my portfolio. Instead of starting from scratch, I took my university LMS assignment and transformed it into something other developers could actually use.

The Problem

My original project was a basic Java CLI for a class. It worked, but it was not something anyone would star on GitHub.

The Transformation

I restructured it into EduAuth, a lightweight authentication and enrollment CLI that teaches auth patterns while being genuinely useful.

What I Added

  • Proper password hashing with SHA-256 and per-user salt generation
  • UUID based session tokens with configurable timeout
  • Role based access control (STUDENT, INSTRUCTOR, ADMIN)
  • Command pattern architecture for clean CLI design
  • File based JSON persistence
  • 20+ JUnit 5 tests
  • Maven build with executable JAR output

What I Learned

  • Refactoring existing code taught me more about architecture than building from scratch
  • Writing JUnit tests after the fact exposed design flaws I did not notice before
  • Documentation and a clear README matter as much as the code for open source adoption

Try It Out

If you are a student learning Java auth patterns, or you need a simple starter template for CLI authentication, give it a look. Stars and feedback are both welcome.
