Structure

Each SSH entry contains:

{
  "user": "root",
  "host": "example.com",
  "port": 22,
  "password": "secret",
  "createdAt": "2025-07-01T12:00:00Z"
}

Requirements

• Go 1.21+
• Linux/macOS terminal (TTY supported)

Security Notes

• Master password is never stored.
• Gate objects are encrypted using ChaCha20-Poly1305.
• Key is derived via Argon2id(master password).
