## Overview

PSS is a local password toolkit with a CLI, a Flask GUI, and an optional encrypted vault. Users generate passwords or passphrases and analyze strength through either interface; vault users create or unlock a vault, then list, add, reveal, or delete entries. Vault storage encrypts entry payloads and protects its data key with password-derived key encryption. The README documents these capabilities; sampled code confirms the GUI, CLI, vault, and cryptographic calls. The password implementation and templates were not sampled, so their internal behavior is not expanded.

Main entry points: [`app.py`](https://github.com/shaikhumaid1/password-security-suite/blob/main/app.py) (Flask GUI), [`pss/vault/store.py`](https://github.com/shaikhumaid1/password-security-suite/blob/main/pss/vault/store.py) (Vault operations), [`cli.py`](https://github.com/shaikhumaid1/password-security-suite/blob/main/cli.py) (Command-line interface), [`pss/core/passwords.py`](https://github.com/shaikhumaid1/password-security-suite/blob/main/pss/core/passwords.py) (Password operations)
