ENC Client Documentation

Part of the ENC Ecosystem

📚 Read the Full Documentation

The ENC Client (enc-cli) is your secure gateway to the ENC ecosystem. It allows you to create, manage, and edit encrypted projects from your local machine, seamlessly integrating them with your favorite tools.

🚀 Installation

Prerequisites

• Python 3.8+
• pip
• sshfs (Optional, required for mounting projects)

  Note: If mounting fails, please reinstall sshfs manually: brew install --cask macfuse && brew install sshfs or restore from backup.

Installation

The recommended way to install ENC Client is via pip:

pip install enc-cli

After installing, run the setup command to handle dependencies (like sshfs) and environment configuration:

enc install

This will:

1. Check for sshfs and attempt to install it if missing.
2. Configure your shell PATH if needed.
3. Guide you to the next step (enc config init).

To verify installation:

enc --version

⚙️ Configuration

Before you can login, you need to tell the CLI where your server is located.

1. Initialize Config

Run the interactive configuration wizard:

enc config init

You will be asked for:

• Server URL: The address of your ENC Server (e.g., http://myserver.com:2222).
• Username: Your assigned username.
• SSH Key Path: Path to your private SSH key (e.g., ~/.ssh/id_ed25519).

To view your current configuration:

enc show

2. SSH Key Setup

For a seamless experience, we recommend using an SSH agent or specifying your key in the config.

Using SSH Agent:

ssh-add -K ~/.ssh/my_enc_key

Using Config File: If you set the key path during enc config init, the CLI will automatically use it for all connections.

🔐 Workflow Guide

1. Login

Start your secure session. This establishes the encrypted tunnel.

enc login

2. Managing Projects

Create a New Project:

enc project init <project-name>
# You will be prompted to set a unique password for this project vault.

List Projects:

enc project list
# Shows all your projects and their mount status.

Remove a Project:

enc project remove <project-name>
# WARNING: This permanently deletes the encrypted vault from the server.

3. Editing Code (Mounting)

This is the magic of ENC. You can mount a remote encrypted project to a local folder.

mkdir ./my-work-folder
enc project mount <project-name> ./my-work-folder
# Enter project password when prompted

Once mounted:

• Open ./my-work-folder in VS Code, Vim, or any editor.
• Files you see are plaintext.
• Files written to disk are instantly encrypted and saved on the server.

4. Logout

When you are done, logout to secure your session.

enc logout

Safety Feature: This command automatically detects and force-unmounts any active project connections to ensure no plaintext access remains.

🛡️ Client-Side Monitoring Protocols

The ENC Client employs active monitoring to ensure session security and clean resource management.

1. Project Integrity Monitor

• Function: Continuously verifies that your local mount points are active and valid.
• Behavior:
  • Checks status every 3 seconds.
  • If a mount point becomes invalid (e.g., directory deleted, connection dropped), it automatically triggers a forced unmount cleanup to remove stale handles.

2. Session Watchdog

• Function: Ties your ENC session to your active terminal window.
• Behavior:
  • Runs as a background process monitoring the Parent PID (your shell).
  • Auto-Logout: If you close your terminal window or the shell process terminates, the watchdog immediately triggers a full enc logout.
  • Signal Handling: Captures termination signals (SIGINT, SIGTERM, SIGHUP) to ensure sessions close gracefully even during unexpected shutdowns.
