Password Management Desktop Application

This was about implementing the security patterns I'd been reading about — hashing, access gating, credential storage — in a real application rather than toy examples.

The app is a desktop password manager built with JavaFX. Users authenticate with a master password (hashed, never stored in plaintext), then manage their credentials through a straightforward CRUD interface backed by MySQL. Jsoup handles any web-scraping needs for site metadata.

The project also served as practice in writing architecture documentation alongside the code. Every design decision — why MySQL over SQLite, how the master password is validated, how the data model constrains access — was documented as it was made, not after the fact.

• ·Credential handling patterns
• ·JavaFX application structure
• ·Relational modeling for credential data
• ·Architecture documentation
• ·JUnit coverage for behavior that should not break quietly
