pwstore

pwstore is a CLI password manager written in Rust. It encrypts your credentials using AES-256-GCM and stores them securely in a local file, with a master password protecting access.

---

Features

• Secure password storage using AES-256-GCM
• Argon2-based key derivation from your master password
• CLI interface with subcommands:
  • add: Encrypt and store new credentials
  • show: Decrypt and view stored credentials
  • rm: Delete a saved credential
  • list: List all stored usernames
• Local, offline storage in the default config directory (~/.config/pwstore on Linux, ~/Library/Application Support/com.mattpatchava.pwstore on macOS)

---

Security

• The master password is never stored
• A unique encryption key is derived using Argon2 from the master password and a randomly-generated salt
• Each credential is encrypted individually using AES-256-GCM
