JPassword

Local password manager with Tkinter — generate, encrypt, and organize by profile.

---

JPassword is a desktop password manager: strong random passwords, Fernet encryption, PBKDF2 key derivation from a master password, and multiple profiles (work, personal, etc.) in separate JSON files.

Everything stays on your machine — no cloud sync, no account.

---

Features

Generate	Configurable length, optional symbols
Save / View	Site name + encrypted password per profile
Profiles	Create, rename, delete; switch at login
Settings	Default length and symbol toggle
Security	Master password unlocks per-profile Fernet key

---

Quick start

git clone https://github.com/krwg/j-password.git
cd j-password
pip install -r requirements.txt
python password_manager.py

On first run, create a profile and choose a strong master password. You need it every time you open the vault.

---

How it works

1. Select or create a profile.
2. Enter master password → derives encryption key (PBKDF2).
3. Generate tab — copy a random password.
4. Save tab — store it under a site label (encrypted in {profile}_passwords.json).
5. View tab — decrypt and read entries after login.

Files created locally: profiles.json, *_passwords.json.

Security notes

• Master password — if you lose it, encrypted data cannot be recovered.
• Salt — demo uses a fixed salt; production use should use random per-profile salts (see roadmap in code history).
• Backup — copy profiles.json and *_passwords.json to a safe place.
• Updates — keep cryptography package current.

---

Requirements

• Python 3.x with tkinter (usually bundled on Windows/macOS; on Linux: python3-tk)
• cryptography — see requirements.txt

---

Roadmap

• Per-profile random salts for PBKDF2
• Password strength meter
• Export / import
• Optional browser autofill
