Password Manager (C++) — XOR Vault

CLI-based password manager in C++. Stores and retrieves credentials from a vault encrypted using XOR with a user-provided key.

Features

• CLI menu interface
• Store/retrieve credentials
• Password generation
• Vault encryption/decryption using XOR with a user key

Security Note

XOR is not secure cryptography. This project is for learning file handling + basic encryption concepts.

Build & Run

g++ -std=c++17 -O2 -o password_manager src/password_manager.cpp
./password_manager

Future Improvements

• Replace XOR with AES-GCM for real encryption
• Add key derivation (PBKDF2 / Argon2)
• Add integrity checks for the vault
• Add unit tests
• Add better error handling and input validation
