# Data Protection

Ecotone enables protection for data sent in messages.

{% hint style="info" %}

### **This module is available as part of Ecotone Enterprise.**

{% endhint %}

Ecotone will help you to encrypt your messeges (Events or Commands) right before they leave and decrypt them when they are received by your domain. In other words, message will remain readable within the application but once they leave the system, secured key is required for reading.

## Installation

```bash
composer require ecotone/data-protection
```

## Configuration

Required `DataProtectionConfiguration` will let you to provide set of encryption keys used within the system.

```php
use Ecotone\DataProtection\Configuration\DataProtectionConfiguration;
use Ecotone\DataProtection\Encryption\Key;

class DataProtection
{
    #[ServiceContext]
    public function dataProtectionConfiguration(): DataProtectionConfiguration
    {
        return DataProtectionConfiguration::create(name: 'primary-key', key: Key::loadFromAsciiSafeString(...)) // first key will be set as default
            ->withKey(name: 'secondary-key', key: Key::loadFromAsciiSafeString(...))
            ->withKey(name: 'default-key', key: Key::loadFromAsciiSafeString(...), asDefault: true) // overwrite default key passing `asDefault: true`
        ;
    }
}
```

{% hint style="warning" %}
Ecotone does not manage your encryption keys. They are used based on given configuration.
{% endhint %}

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.ecotone.tech/modules/data-protection.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
