🔐 VaultCLI

A simple C++ command-line password manager with file persistence, encryption, and multithreaded auto-save.

---

Features

• Add / view / search / delete password entries
• Encrypted local file storage (XOR-based)
• Auto-save using background thread
• Thread-safe operations with mutex
• Clean modular C++ design (OOP)

---

Tech Stack

• C++
• STL (vector, string)
• File I/O (fstream)
• Multithreading (thread, mutex)

---

Note

This project uses XOR-based encryption for educational purposes only.
It is not cryptographically secure and should not be used for real-world sensitive data.

---

🚀 Future Improvements

• Replace XOR-based encryption with a secure algorithm (AES-256 or ChaCha20)
• Add proper key derivation from user password (PBKDF2 / Argon2)
• Introduce authenticated encryption (AEAD) to prevent tampering
• Improve secure handling of sensitive data in memory
• Add file integrity checks to detect corruption or modification
• Improve CLI usability and input validation
• Add export/import functionality for vault backups
