Bud Sudo Tool

Store and use sudo password for automated root commands. Essential companion for skills that need sudo access (like vpn-mesh).

Sudo Tool 🔐

Securely store your sudo password for automated root commands. No more re-entering passwords for every sudo call.

Essential for skills that need elevated permissions — like vpn-mesh which installs WireGuard automatically.

---

Setup (One-time)

# Configure your sudo password (one-time only)
sudo-tool setup

You'll be prompted to enter your sudo password. It's encrypted with OpenSSL and stored in ~/.openclaw/sudo-tool/ — never in plaintext.

---

Usage

# Check if configured
sudo-tool status

# Run any command with sudo
sudo-tool apt update
sudo-tool apt install wireguard-tools
sudo-tool systemctl restart nginx

# Reset (remove stored password)
sudo-tool reset

---

How It Works

1. Setup — encrypts your password with OpenSSL (AES-256-CBC) using a random salt, stores in ~/.openclaw/sudo-tool/.password.enc
2. Use — decrypts password and pipes to sudo -S (reads from stdin)
3. Secure — password never appears in process list, temp files are deleted immediately

---

Security Notes

• Password is encrypted with a random salt — not recoverable without your system
• Uses OpenSSL PBKDF2 for key derivation (100k iterations)
• No plaintext passwords stored anywhere
• Temp files deleted immediately after use

---

Required By

• vpn-mesh — needs sudo to auto-install WireGuard
