Encriptar Archivos Linux 14,51€

Necesito implementar encriptación de datos en un servidor Linux para proteger exclusivamente archivos y documentos. Mi objetivo es contar con una solución sencilla y funcional que deje los ficheros cifrados en reposo sin complicar el resto del sistema. Lo que espero recibir: • Revisión rápida del entorno (distro y versión) y selección de la herramienta adecuada — por ejemplo LUKS, GPG o eCryptfs. • Guía paso a paso (o script básico) para instalarla, configurarla y probarla. • Instrucciones claras para añadir nuevos archivos al volumen/contenedor cifrado y para realizar copias de seguridad igualmente protegidas. • Documento breve con comandos clave y cómo revertir cambios si fuera necesario. Valoro una entrega ligera y bien comentada, pensada para que yo mismo pueda reproducirla con facilidad. Hello again, I completely understand your message and deeply value the clarity with which you've outlined your situation and your goals. Please don't apologize for the explanation; it's essential for me to be able to offer you precise and useful help. Seeking maximum privacy for your work and research is completely legitimate and a fundamental right. To facilitate communication with the IT professional who will be helping you, I have structured the response as a set of **clear and direct technical specifications**. These are the steps and configurations you need to implement to achieve your objective. ### Summary of the Technical Solution The comprehensive solution to your problem consists of three distinct parts: 1. **Operating System and Encryption:** Transform your Ubuntu laptop into an **amnestic and encrypted** system using Tails and TrueCrypt/VeraCrypt. This ensures that all your work disappears when you shut down the computer and that your documents are protected. 2. **Browsing and Connecting to DeepSeek:** Use a **disposable and anonymous email address** to create a DeepSeek account, thus avoiding any link to Google. Furthermore, it is crucial to configure the privacy settings within the DeepSeek account itself to prevent your conversations from being used to train the model. 3. **Running the AI Locally (The "Holy Grail" of Privacy):** The most radical and private alternative is not to use the DeepSeek website at all, but rather to **download and run the AI model itself on your computer** without an internet connection. ### Technical Instructions for Your Freelance IT Specialist Below are the detailed instructions you can copy and paste to give to the technician. #### Phase 1: Hardware Preparation and Booting from Tails You will need an external hard drive or a large capacity USB stick (minimum 32 GB, 64 GB or more recommended). 1. **Creating the Tails USB:** * Download the Tails ISO image from the official website: `[login to view URL]` . * Verify the cryptographic signature of the download to ensure its authenticity (Tails has a step-by-step guide for this). * Use a tool like `Etcher` or the `dd` command in another Linux terminal to write the ISO to the USB drive. **Warning:** This process will erase all content on the USB drive. 2. **BIOS/UEFI Configuration:** * Access the laptop's BIOS/UEFI settings (usually by pressing F2, F10, F12, or Del during startup). * Disable **Secure Boot**. * Configure the boot order so that the first device is the USB drive where Tails was written. 3. **First Boot and Encrypted Persistence Configuration:** * Boot the laptop from the Tails USB drive. * Connect to the internet via Tor (Tails will do this by default). * In the Tails welcome screen, set a password for the root user (this is necessary to temporarily install additional software). * Once on the desktop, go to the menu "Applications" -> "Tails" -> "Configure persistent volume". * Create a persistent volume with a **strong and secure password**. This encrypted space (using LUKS, the standard technology on Linux) will store your documents and configurations between sessions. #### Phase 2: Additional File Encryption with TrueCrypt/VeraCrypt Inside Tails' persistent volume (which is already encrypted), you can add an extra layer of security for specific projects using a VeraCrypt container (the successor to TrueCrypt). 1. **Installing VeraCrypt on Tails (temporary):** * In a Tails session, download the VeraCrypt package for Linux from its official website: `[login to view URL]`. * Install it (this installation will be lost upon shutdown, but it's only needed to create the container). 2. **Creating the File Container:** * Open VeraCrypt and select "Create Volume". * Choose "Create a standard VeraCrypt volume". * Select "Select File" and save the file inside your Tails persistent directory (e.g., `/home/amnesia/Persistent/[login to view URL]`). * Choose an encryption algorithm (AES is an excellent and fast option) and a hash algorithm (SHA-512). * Define the size of the container according to your needs. * Set a **different and also very secure password**. * Format the volume. You will now have a virtual encrypted "disk" that you can mount and unmount from VeraCrypt to work with your most sensitive files. #### Phase 3: Configuring Privacy on DeepSeek (Web) To interact with me via the web with the maximum privacy the platform currently allows, you must follow these steps **within a Tails session**: 1. **Creating an Anonymous Email Account:** * Use the Tor browser (included in Tails) to create an account on an anonymous and ephemeral email service like `[login to view URL]` or `[login to view URL]` (without providing any personal data or a recovery phone number). 2. **Registering on DeepSeek:** * Go to the DeepSeek website and register using the anonymous email address you just created. **Do not use Google or any other social network.** 3. **Privacy Settings within DeepSeek (CRITICAL!):** * Once registered and logged into your DeepSeek account, look in the settings for the data privacy option. * Locate the option that says something similar to **"Data for improving the model"** or **"Data for model training"** . * **Explicitly deactivate it.** According to the documentation, this prevents your conversations from being used to train and improve the AI model, although technically the conversations might still be stored on the servers . #### Phase 4: The Definitive Solution: Running DeepSeek Locally with Ollama (Recommended) This is the alternative that would give you total independence from external servers and maximum privacy. It involves running a DeepSeek model directly on your computer, with no need for an internet connection once installed . 1. **Installing Ollama:** * Open a terminal on your system (this can be in a Tails session with persistence, or better yet, on a standard Ubuntu system if you decide not to use Tails for this). * Run the command: `curl -fsSL [login to view URL] | sh` . * This command will download and install Ollama, a tool that simplifies running AI models locally. 2. **Downloading and Running the DeepSeek Model:** * Once Ollama is installed, in the same terminal, run: `ollama run deepseek-r1:8b` . * This command will download the DeepSeek-R1 model with 8 billion parameters (approximately 4.9 GB) and run it. * The first download may take some time, but once completed, you will be able to interact with DeepSeek directly from the terminal, **without an internet connection and with all responses saved locally on your encrypted hard drive (or persistent volume)**. To exit the chat, type `/bye`. ### Summary Table of Tools and Functions | Tool | Primary Function | Key Configuration for Your Case | | :--- | :--- | :--- | | **Tails** | "Amnestic" operating system running from a USB. | Create and configure the **encrypted persistent volume**. | | **VeraCrypt** | File and container encryption. | Create an **encrypted file container** inside the persistent volume. | | **Guerrilla/ProtonMail** | Anonymous and disposable email. | Use it to **register on DeepSeek without linking your identity**. | | **DeepSeek Settings** | Web account privacy adjustments. | **Disable data usage for model training**. | | **Ollama** | Local AI model manager and runner. | Install it and run `ollama run deepseek-r1:8b` for a **local, offline AI**. | ### Final Thoughts and an Important Note The tools you have chosen (Tails and TrueCrypt/VeraCrypt) are the gold standard for privacy and anonymity. A competent technician will be familiar with them. However, it is crucial that you are aware of an important limitation. According to DeepSeek's official privacy policy, even if you disable the training option, the company **does collect data** such as your IP address, device information, unique identifiers, and of course, the content of your conversations while you use their web service. This information is stored on servers located in China and could be subject to that country's laws . **Therefore, the recommendation to run DeepSeek locally with Ollama is not a simple add-on, but the cornerstone of your privacy strategy.** It completely isolates you from that data exchange with DeepSeek's servers. If your technician has questions about the resource consumption when running the model locally (the 8B model can run on machines with 8GB of RAM or more) or about configuring the network in Tails to allow the initial download of the model, feel free to ask me again. I can go into more detail on those technical aspects. You are on the right track to achieving the private and secure work environment you need. Best of luck with the project.
